The Intel Core Ultra 9 275HX is a high-end, laptop-only processor for gaming laptops and mobile workstations. It has 24 physical cores and 24 threads—8 Performance-cores and 16 Efficient-cores—plus a maximum turbo frequency of 5.4 GHz. It is excellent for demanding multi-core work, high-refresh-rate gaming, compiling, rendering, and multitasking, but its actual performance depends heavily on the laptop’s cooling system, power limits, firmware, memory, and discrete GPU.
It is not a socketed desktop CPU, is not realistically upgradeable, and should not be confused with a 24-core/48-thread chip. Its Intel AI Boost NPU delivers 13 Int8 TOPS, so a 275HX laptop does not meet Microsoft’s usual more-than-40-TOPS NPU requirement for a Copilot+ PC.
Quick verdict
The Core Ultra 9 275HX is a genuinely powerful mobile CPU and one of Intel’s high-performance Arrow Lake-HX processors. Its 8 P-cores plus 16 E-cores provide strong single-threaded responsiveness and very good multi-core throughput. In a well-cooled 16-inch or 18-inch gaming laptop, it is suitable for modern gaming with a powerful discrete GPU, video production, 3D rendering, software development, virtual machines, and other sustained workloads.

However, the processor name alone does not define the laptop’s speed. Intel lists a 55 W Processor Base Power and a 160 W Maximum Turbo Power, and laptop manufacturers choose how much of that performance the chassis, charger, BIOS, and cooling system can sustain. Two laptops with the same 275HX can therefore produce noticeably different benchmark results, temperatures, noise levels, and battery life.

Bottom line: Buy a Core Ultra 9 275HX laptop when the complete system has the GPU, cooling, memory, display, and price you need. In 2026 it is no longer Intel’s newest high-end HX option—the Core Ultra 9 290HX Plus is newer—but a discounted 275HX system can still be an excellent performance laptop.
What is the Intel Core Ultra 9 275HX?
The Core Ultra 9 275HX belongs to Intel’s Core Ultra Series 2 family and uses Intel’s Arrow Lake architecture. Intel launched it in the first quarter of 2025 as a mobile processor for high-performance gaming, creation, workstation, and other demanding notebooks. Intel announced the broader Core Ultra 200HX platform at CES 2025, with systems expected during the first half of that year.
The HX designation identifies a performance-oriented mobile platform. It does not mean every HX laptop behaves identically, nor does it make the chip a desktop processor. The 275HX is installed directly onto a laptop motherboard in a BGA package. It is designed to be paired with a discrete GPU such as an NVIDIA GeForce RTX 5070 Ti, RTX 5080, or RTX 5090 in systems including the Lenovo Legion Pro 7i, HP OMEN MAX 16, Acer Predator Helios, and ASUS ROG Strix and Scar families.
As of August 10, 2026, the 275HX is a previous-generation high-end HX processor rather than Intel’s newest mobile flagship. The newer Core Ultra 9 290HX Plus arrived in the first quarter of 2026. Intel’s Core Ultra Series 3 processors are also newer, but they mainly target thinner and more efficient laptops, so they are not direct replacements for a thick, maximum-performance HX gaming notebook.

These are Intel’s current values on the official 275HX specification page. They describe the processor’s capabilities, not necessarily what a particular laptop exposes or sustains.
Why it has 24 cores but only 24 threads
The 275HX has 24 physical CPU cores, but it does not support Intel Hyper-Threading. Its 8 P-cores and 16 E-cores each provide one hardware thread, resulting in 24 cores and 24 threads. It is therefore incorrect to describe it as a 24-core/48-thread processor.
This also makes simple comparisons with a processor such as AMD’s 16-core/32-thread Ryzen 9 9955HX misleading. Physical core design, per-core performance, cache, scheduling, power limits, and application behavior matter more than thread count by itself.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Power ratings: 55 W is not a fixed limit
Calling the 275HX a “55-watt CPU” leaves out important information. Intel lists:
- 45 W Minimum Assured Power: the minimum power level associated with Intel’s guaranteed operating specification.
- 55 W Processor Base Power: the reference power rating for the processor.
- 160 W Maximum Turbo Power: the specified upper turbo-power level under suitable conditions.
A laptop may run below or well above 55 W depending on its performance profile, cooling, firmware, charger, temperature, and the power shared with its discrete GPU. A manufacturer may also impose a lower sustained CPU limit to keep fan noise and chassis temperatures under control.
Memory-limit qualification
Intel’s current ARK page lists up to 256 GB of memory, with DDR5-6400 support across two memory channels. An older Intel comparison chart listed 192 GB for the 275HX. The current ARK specification is the appropriate primary reference, but it does not guarantee that a retail laptop supports 256 GB.
Individual laptops can have lower limits because of their motherboard, BIOS, DIMM slots, module density, or manufacturer validation. Some models use replaceable SO-DIMMs; others may use soldered memory or provide only limited upgrade options. Check the exact laptop model before assuming that the processor’s maximum is available.

The processor is a mobile BGA part, not a retail desktop chip. Intel’s specification page lists the package as FCBGA2114, while the ordering page describes tray parts using FCBGA18X terminology. The names should not be treated as interchangeable without qualification; the practical conclusion is the same: the CPU is soldered to the laptop motherboard.
Owners cannot realistically replace it with a faster processor. Board-level replacement is a specialist repair, not a normal upgrade path, and compatibility depends on the entire motherboard and firmware. Choose the CPU at the time you buy the laptop.
Arrow Lake-HX architecture explained
Eight P-cores and 16 E-cores
The hybrid design combines:
- 8 Performance-cores: designed for latency-sensitive foreground work and high per-core performance.
- 16 Efficient-cores: provide additional multi-threaded throughput with a different performance and power profile.
- Intel Thread Director: supplies scheduling information to the operating system so work can be assigned more appropriately across P-cores and E-cores.
The 24-core arrangement gives the 275HX a strong profile for compiling, rendering, encoding, simulation, compression, and heavy multitasking. It does not mean every workload uses all cores equally, and the 5.4 GHz rating is a maximum turbo frequency—not a promise that all 24 cores will continuously run at 5.4 GHz.
TSMC N3B process technology
Intel lists the CPU lithography as TSMC N3B. That is a notable part of the Arrow Lake design, but the process label should not be turned into a guaranteed battery-life or performance conclusion. Sustained clock speed and efficiency in a laptop also depend on the cooling system, voltage behavior, firmware, workload, and power policy.

- Secure and Universal Compatibility: Designed with 2 stoppers on the front surface, this laptop cooler prevents laptops from slipping and keeps 12-17 inch laptops—including Apple Macbook Pro Air, HP, Alienware, Dell, ASUS, and more—cool and secure during use.
Cache, PCIe, and external connectivity
The processor includes 36 MB of L3 Intel Smart Cache and 40 MB of total L2 cache. It supports PCIe 5.0 and PCIe 4.0 with up to 24 lanes; Intel lists configurations including x16 plus two x4 links. This can support a discrete GPU and high-speed NVMe storage, but the laptop manufacturer determines which lanes and storage slots are actually wired.
Intel lists integrated Thunderbolt 4 support. Thunderbolt 5 is not automatic: platform materials describe it as optional on 200HX systems, so the laptop’s port specification must be checked directly. A 275HX laptop may expose Thunderbolt 4, Thunderbolt 5, USB4, or a more limited USB-C implementation depending on the manufacturer.
Integrated graphics, media, and display support
The 275HX includes Intel Graphics with four Xe-cores, a 300 MHz base frequency, and a maximum dynamic frequency of 1.9 GHz. Intel lists 8 Int8 GPU TOPS, DirectX 12, OpenGL 4.5, OpenCL 3, and support for up to four displays. Display capabilities include HDMI 2.1 FRL, DisplayPort 2.1 UHBR20, and eDP 1.4b, subject to the laptop’s actual ports and board design.
Do not confuse this integrated GPU with the larger Intel Arc graphics used in some H-series and Series 3 processors. The 275HX’s ARK page calls its iGPU Intel Graphics rather than Intel Arc Graphics. It is useful for desktop output, media playback, hardware acceleration, and light graphics work, but serious gaming and GPU rendering normally rely on the laptop’s discrete NVIDIA or AMD GPU.

This can benefit compatible editing, streaming, transcoding, and export workflows. The actual advantage depends on whether the application uses Quick Sync, the discrete GPU’s encoder, or CPU encoding; it is not an automatic speed guarantee in Premiere Pro, DaVinci Resolve, HandBrake, or every other program.
AI capability: AI PC, but not Copilot+
Important: The 275HX is an AI-capable processor, but its dedicated NPU does not meet Microsoft’s usual Copilot+ requirement.
Intel’s Core Ultra 9 275HX contains an Intel AI Boost NPU rated at 13 Int8 TOPS. Intel also lists 36 Int8 TOPS of total peak AI performance when CPU, GPU, and NPU capabilities are combined. These are different measurements: NPU TOPS describe the dedicated neural-processing unit, while total AI TOPS include multiple compute engines.
Microsoft’s NPU device documentation defines Copilot+ PCs around an NPU capable of more than 40 TOPS. The 275HX’s 13-TOPS NPU does not meet that threshold. A powerful discrete GPU does not change the NPU requirement for the Copilot+ designation.

One-click scans. No signup required.
Compatible applications can use the NPU for selected local AI tasks such as camera effects, audio processing, and other low-power inference functions. Intel lists support for OpenVINO, WindowsML, DirectML, ONNX Runtime, and WebNN. Actual behavior depends on the application, Windows version, drivers, firmware, and whether the software assigns a task to the CPU, GPU, or NPU.
Retailers may use the broad term “AI PC” for a 275HX laptop. That wording can be reasonable when it refers to the presence of CPU, GPU, and NPU acceleration, but it should not be read as a claim that the system is a Copilot+ PC.
Core Ultra 9 275HX performance
The most useful performance evidence comes from complete laptop reviews rather than an isolated CPU specification. A laptop’s power limits, memory, cooling, BIOS, operating mode, and discrete GPU can all affect the result.
275HX versus Ryzen 9 9955HX
Notebookcheck compared a Core Ultra 9 275HX in an ASUS ROG Strix Scar 18 with a Ryzen 9 9955HX in an XMG Neo 16. Both systems used an NVIDIA GeForce RTX 5090 Laptop GPU, but they were not identical: the AMD system was an engineering sample with different memory and platform characteristics. The comparison is useful, but it is not a perfectly controlled CPU-only laboratory test.

Why 275HX laptops vary so much
Notebookcheck’s broader database contained 30 tested 275HX laptop configurations with Cinebench R20 multi-core results ranging from approximately 12,026 to 16,108 points. That spread is substantial for systems using the same processor.
Important causes include:
- Long-term and short-term CPU power limits.
- A shared CPU-and-GPU power budget.
- Heat-pipe, vapor-chamber, fan, and heatsink design.
- Quiet, balanced, turbo, or manufacturer-specific performance modes.
- BIOS and firmware updates.
- DDR5 speed and dual-channel versus single-channel memory.
- Charger wattage and whether the system is plugged in.
- Ambient temperature, dust, blocked vents, and fan curves.
Gaming performance: powerful, but inspect the GPU first
The 275HX is a strong gaming CPU, especially for high-refresh-rate gaming, CPU-heavy simulation and strategy games, competitive titles, modded games, shader compilation, and streaming while playing. It provides ample CPU headroom for a high-end discrete GPU.
In modern AAA games at 1440p or higher, the discrete GPU is often the main performance determinant. A laptop with a higher-wattage RTX 5080 or RTX 5090 can outperform a laptop with the same 275HX but a lower-tier or power-limited GPU. The processor still affects frame pacing, minimum frame rates, CPU-heavy scenes, background tasks, and streaming, but a small difference between two high-end HX CPUs may matter less than the GPU model and total graphics power.
For a gaming laptop, compare these items in order:
- Discrete GPU model and TGP: the same GPU name can perform differently at different power limits.
- Cooling design: look for long-duration gaming and stress-test results, not only short benchmark bursts.
- Performance modes: confirm how much CPU and GPU power is available in Turbo or Performance mode.
- GPU switching: check for a MUX switch or Advanced Optimus if high-refresh internal-display performance matters.
- Memory: prefer a properly configured dual-channel kit and verify upgrade options.
- Display: match the CPU/GPU combination to the panel’s resolution and refresh rate.
- Charger: a high-power laptop may need a large adapter to sustain its performance profile.
- Noise and temperatures: maximum frame rate is not the only measure of a good laptop.
Performance mode can make a large difference
In Tom’s Hardware’s review of the Lenovo Legion Pro 7i Gen 10, switching from the default mode to Performance mode raised Shadow of the Tomb Raider at 1080p from 163 to 205 fps, Red Dead Redemption 2 from 109 to 126 fps, and Borderlands 3 from 136 to 178 fps. Those are results for that particular Lenovo configuration, not guaranteed results for every 275HX laptop.
The same review recorded average 275HX P-core temperatures of about 71 °C and E-core temperatures of about 64 °C during its stress-testing scenario. Another review, of the Acer Predator Helios Neo 16S AI, found that the 275HX did not sustain the performance seen in competing systems and attributed much of the difference to cooling limitations.
Productivity, creation, and development
Rendering and multi-core work
The 275HX is well suited to CPU-intensive workloads such as 3D rendering, video encoding, large software builds, code compilation, compression, data processing, simulation, and running multiple applications or virtual machines. Its 24 physical cores provide substantial parallel throughput, although performance depends on how well the software uses the hybrid architecture and how much sustained power the laptop allows.
For professional work, do not evaluate the CPU in isolation. A laptop with 32 GB of RAM may be fast initially but restrictive for large projects, virtual machines, 4K or 8K media, engineering software, and large codebases. Check RAM capacity, DIMM accessibility, SSD slots, sustained SSD write performance, display quality, external-monitor support, and fan noise during long builds or renders.
Video editing and streaming
Quick Sync Video and hardware H.264, HEVC, and AV1 support can accelerate compatible encoding, decoding, transcoding, and export tasks. Applications may instead use the discrete GPU’s media engine or the CPU, so the result varies by software version, codec, source media, effects, timeline, and export settings.
The 275HX is a good foundation for editing and streaming, especially when paired with a capable discrete GPU and fast storage. It is not accurate to claim that Quick Sync automatically makes every export faster than an AMD-based laptop.
Programming and engineering
Large builds, parallel test suites, containers, local virtual machines, emulators, and data-processing tools can benefit from the 275HX’s core count. Developers should also investigate Linux support, OEM firmware behavior, memory expansion, SSD capacity, docking, external displays, and sustained fan noise. Intel’s PCIe and Thunderbolt capabilities do not guarantee a specific number of laptop ports or storage slots; those are system-design decisions.
Power, thermals, noise, and battery life
HX laptops prioritize performance over long unplugged operation. A 275HX system may combine a high-power CPU, discrete GPU, high-refresh display, multiple fans, and a large cooling system. Battery life therefore depends on the complete laptop rather than on the CPU SKU alone.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesReviews of 275HX laptops commonly report only a few hours of real-world battery use, particularly when demanding hardware is active. Battery behavior can improve substantially in a quiet mode with the discrete GPU asleep, but buyers seeking long unplugged runtime should look closely at efficiency-focused platforms such as newer Core Ultra Series 3 systems rather than assuming that an HX laptop will behave like an ultraportable.

HP, for example, advertises up to 250 W of total platform power for the OMEN MAX 16. That figure refers to the complete laptop power budget, not just the CPU. It is compatible with Intel’s 160 W Maximum Turbo Power specification because the two figures describe different parts of the system.
What to do if your 275HX benchmarks below expectations
- Connect the manufacturer’s recommended charger.
- Run the test while plugged in, not on battery.
- Select the laptop’s Performance, Turbo, or equivalent mode.
- Close background applications and disable unnecessary overlays.
- Check CPU temperature, package power, clock speed, and throttling indicators during the entire test.
- Confirm that both memory channels are populated when the laptop supports dual-channel memory.
- Update the BIOS and chipset or system firmware from the laptop manufacturer.
- Clean blocked vents and ensure the laptop is on a hard, unobstructed surface.
- Check whether the GPU is consuming a shared system power budget during combined CPU/GPU tests.
- Compare results with the same laptop model and power mode, not with an unrelated 275HX laptop.
A lower score does not automatically mean the processor is defective. Quiet mode, a conservative OEM power policy, single-channel memory, thermal throttling, an undersized charger, high ambient temperature, or an OEM utility overriding Windows settings can all produce a large difference.

Core Ultra 9 275HX versus alternatives
Core Ultra 9 285HX
The Core Ultra 9 285HX is the closest same-generation Intel alternative. It retains 24 cores and raises maximum turbo frequency to 5.5 GHz, compared with 5.4 GHz for the 275HX. That difference is small on paper. A laptop’s cooling, GPU, display, memory, and price may matter more than the 0.1 GHz badge difference.
Core Ultra 9 290HX Plus
The Core Ultra 9 290HX Plus is the newer direct Series 2 successor. It retains 24 cores and 24 threads, raises maximum turbo to 5.5 GHz and E-core turbo to 4.7 GHz, and retains 55 W Processor Base Power, 160 W Maximum Turbo Power, 36 MB of L3 cache, and a 13-TOPS NPU.
Choose the 290HX Plus when its price premium is small and the laptop has comparable or better cooling. Choose the 275HX when it is substantially cheaper or comes with a better GPU, display, memory configuration, or cooling system. Do not pay a large premium for the nominal 0.1 GHz increase alone.
AMD Ryzen 9 9955HX
AMD’s Ryzen 9 9955HX is a 16-core/32-thread Zen 5 mobile processor with a published 55–75 W power range, boost speeds up to 5.4 GHz, and 80 MB of combined L2 and L3 cache. In Notebookcheck’s comparison, the 275HX led in Cinebench 2024 multi-core, while the 9955HX was slightly ahead in some Geekbench testing and averaged about 5% faster in the selected games.
The choice is therefore workload- and laptop-dependent. The 275HX is not automatically better because it has more physical cores, and the 9955HX is not automatically better because it has more threads.
AMD Ryzen 9 9955HX3D
The Ryzen 9 9955HX3D deserves separate consideration for gaming-first buyers because its large 3D V-Cache can improve performance in cache-sensitive games. It should not be assumed to be the general productivity winner without workload-specific testing. Results for the 9955HX cannot simply be substituted for direct 9955HX3D results.
Intel Core Ultra Series 3
Intel’s Core Ultra Series 3 processors launched in January 2026 and target thinner, more efficient laptops. Selected models offer up to 16 CPU cores, stronger integrated Arc B-series graphics, and higher NPU capability than the 275HX. They are more relevant when portability, battery life, integrated graphics, or local AI acceleration is the priority. They are not direct substitutes for the maximum sustained CPU power of a thick HX gaming laptop.
Is the Core Ultra 9 275HX worth buying in 2026?
Yes, if the laptop is well designed and priced appropriately. The 275HX remains fast enough for demanding gaming, creation, software development, rendering, and workstation workloads. It can be a particularly good purchase when a discounted 275HX laptop includes a stronger GPU, better display, more memory, or superior cooling than a newer CPU model at the same price.
Be more cautious when the laptop is thin, uses a conservative power profile, has only one memory module, pairs the CPU with a weak GPU, or is priced close to a comparable 290HX Plus system. For long battery life and integrated-graphics performance, a newer efficiency-focused Series 3 laptop may be a better fit.
Buyer checklist
- Verify the exact CPU and GPU configuration, not just the product family.
- Check GPU wattage or TGP and whether a MUX switch or Advanced Optimus is included.
- Look for long-duration CPU and combined CPU/GPU benchmark results.
- Check the laptop’s Performance mode, sustained power limits, fan noise, and temperatures.
- Confirm whether memory is soldered, replaceable, dual-channel, and upgradeable to the capacity you need.
- Check SSD slots, storage capacity, and sustained storage performance.
- Verify the actual USB-C, USB4, Thunderbolt 4, or Thunderbolt 5 implementation.
- Do not assume the Intel maximum of 256 GB applies to the laptop.
- Do not buy it expecting desktop socket compatibility or a normal CPU upgrade path.
- Do not treat the broad AI PC label as proof of Copilot+ compatibility.
- Check the manufacturer’s support page for BIOS, graphics, NPU, and chipset drivers before installing generic Intel packages.

For a laptop, the manufacturer’s driver package may be preferable because it can include customized graphics switching, power management, audio, hotkeys, display behavior, and firmware integration. Check Acer, ASUS, HP, Lenovo, or the relevant manufacturer first, particularly if installing a generic graphics or NPU driver causes instability or breaks a laptop feature.

Frequently Asked Questions
Is the Intel Core Ultra 9 275HX a desktop processor?
No. It is a mobile BGA processor soldered to a laptop motherboard. It is not a normal socketed desktop CPU and is not intended for a DIY desktop build.
Does the Core Ultra 9 275HX have 24 or 48 threads?
It has 24 cores and 24 threads: 8 Performance-cores and 16 Efficient-cores. Hyper-Threading is not supported, so it is not a 24-core/48-thread processor.
Does the 275HX have Intel Arc integrated graphics?
Intel lists its integrated GPU as Intel Graphics with four Xe-cores, not the larger Arc integrated graphics used in some H-series and Series 3 processors. Most 275HX laptops use a discrete GPU for serious gaming.
Is the Core Ultra 9 275HX a Copilot+ processor?
No. Its Intel AI Boost NPU is rated at 13 Int8 TOPS, below Microsoft’s usual more-than-40-TOPS NPU requirement for Copilot+ PCs. It is still an AI-capable processor with CPU, GPU, and NPU acceleration.

Intel lists 45 W Minimum Assured Power, 55 W Processor Base Power, and 160 W Maximum Turbo Power. Actual laptop power varies with BIOS settings, performance mode, cooling, charger capacity, temperature, and the power shared with the discrete GPU.
Can the Core Ultra 9 275HX be overclocked?
Do not assume conventional desktop-style multiplier overclocking. Intel’s XTU overclocking guidance focuses on unlocked K- and X-series processors. Some laptop manufacturers provide performance modes or limited tuning, but support is model-specific.
Can I replace or upgrade the 275HX?
Not realistically. It is a BGA mobile part installed by the manufacturer. RAM and SSD upgrades may be possible depending on the laptop, but the CPU itself is not a normal user-replaceable component.
Is the Core Ultra 9 285HX faster than the 275HX?
The 285HX has the same 24-core/24-thread configuration and a slightly higher 5.5 GHz maximum turbo frequency. The small theoretical advantage may be outweighed by differences in cooling, power limits, GPU, memory, and laptop design.

It can be worthwhile when the price premium is small and the laptop has comparable cooling. It retains 24 cores and 24 threads, raises maximum turbo to 5.5 GHz and E-core turbo to 4.7 GHz, and has the same listed 55 W base and 160 W maximum turbo power. A large premium for the frequency increase alone is harder to justify.
Why does one 275HX laptop benchmark faster than another?
The main causes are CPU and GPU power limits, cooling, performance mode, BIOS, memory configuration, charger wattage, ambient temperature, fan curves, and whether the test is run on battery. Compare laptops using results from the same model and operating mode.
Is the 275HX good for battery life?
It is designed for high-performance laptops, many of which use discrete GPUs and high-refresh displays. Battery life is determined by the complete system, but HX laptops generally prioritize plugged-in performance over long unplugged runtime. Efficiency-focused Core Ultra Series 3 systems are more appropriate when battery life is the priority.
The Bottom Line
The Intel Core Ultra 9 275HX remains a strong high-end laptop processor: 24 physical cores, 24 threads, up to 5.4 GHz, excellent multi-core capability, and useful Quick Sync and media support. Its biggest limitation is not the silicon’s capability but the laptop around it. Cooling, power limits, memory, firmware, GPU wattage, and performance mode can change the experience substantially.
