The Intel Core Ultra 7 258V is an eight-core mobile processor from Intel’s Core Ultra 200V family, also known as Lunar Lake. It is designed for premium thin-and-light laptops and tablets rather than desktop PCs or user-upgradeable CPU platforms.
Its main strengths are low platform power, integrated Intel Arc graphics, hardware AI acceleration and fast on-package LPDDR5X memory. The trade-off is limited upgradeability: laptops using this processor normally have soldered or package-mounted memory, with no replaceable SO-DIMM RAM.

There are eight threads in total because Intel Hyper-Threading is not supported. This is an important distinction when comparing listings: the processor has eight cores and eight threads, not eight cores and 16 threads.
The “Ultra 7” name identifies Intel’s product tier. It does not mean the chip has seven cores.
Power consumption and laptop performance
Intel lists three power figures for the 258V:
- Minimum Assured Power: 8 W
- Processor Base Power: 17 W
- Maximum Turbo Power: 37 W
These numbers describe the processor’s defined power ranges, not a fixed reading that every laptop will show. A manufacturer can use different cooling hardware, firmware limits, battery settings and chassis designs. Two laptops with the same 258V can therefore deliver different sustained performance and fan noise.
The 17 W figure is also not the maximum power that the complete laptop can consume. The screen, storage, wireless hardware, memory and other components add to system power use. For comparisons, check independent testing of the specific laptop rather than judging it from the processor name alone.
Integrated Intel Arc 140V graphics
The 258V includes an Intel Arc 140V integrated GPU based on Intel’s Xe2 architecture. It has eight Xe cores, a 400 MHz graphics base frequency and a maximum dynamic frequency of 1.95 GHz.
| Graphics capability | Intel-listed specification |
|---|---|
| GPU | Intel Arc 140V |
| Xe cores | 8 |
| Peak GPU AI throughput | 64 Int8 TOPS |
| DirectX | 12.2 |
| OpenGL | 4.6 |
| OpenCL | 3.0 |
| Maximum displays | 3 |
The graphics engine supports hardware encoding and decoding for H.264, H.265/HEVC and AV1, along with Intel Quick Sync Video. H.266/VVC is listed as decode-only.

These are processor capabilities, not a promise that every 258V laptop will include those ports or drive those resolutions. The laptop manufacturer decides which outputs are physically wired and enabled.
What’s actually slowing this PC down?

AI hardware: GPU, NPU and CPU
The 258V has three potential sources of AI acceleration:
| Component | Intel-listed peak throughput |
|---|---|
| Intel Arc 140V GPU | 64 Int8 TOPS |
| Intel AI Boost NPU | 47 Int8 TOPS |
| Overall peak | 115 Int8 TOPS |
The NPU is Intel AI Boost. Intel lists support for OpenVINO, WindowsML, DirectML, ONNX Runtime and WebNN, as well as Windows Studio Effects support.
TOPS is a theoretical throughput measure. It does not directly predict how quickly an application will run. Actual results depend on the model, numerical precision, drivers, framework and whether the workload runs on the CPU, GPU or NPU. Intel’s broader Lunar Lake material describes an NPU of up to 48 TOPS, but the specific 258V product page lists 47 NPU TOPS. For this processor, 47 is the more precise SKU figure.
Memory and upgradeability
The 258V supports two channels of LPDDR5X memory at up to 8,533 MT/s, with a maximum capacity of 32 GB. Lunar Lake places the memory on the same package as the processor. This can reduce board space and data-movement power, but it makes memory capacity a design choice made when the laptop is built.

A typical 258V laptop will not have user-replaceable DDR5 SO-DIMMs, and the processor itself cannot be removed and upgraded like a desktop CPU. If the choice is between 16 GB and 32 GB, the 32 GB configuration is the safer long-term option for large documents, development tools, virtual machines, photo work or heavier multitasking.

Storage, Thunderbolt and PCI Express
Intel lists support for Thunderbolt 4 and up to eight PCI Express lanes. The available links include:
- One PCIe 5.0 x4 link, configurable as x2 or x4
- One PCIe 4.0 x4 link, configurable as x1, x2 or x4
Those capabilities do not guarantee a particular laptop will provide every connection. The OEM determines whether a system includes Thunderbolt 4, which USB-C ports are connected to it, what PCIe link is used for the SSD and whether any expansion lanes are exposed.
Security and virtualization support
The 258V supports Intel VT-x, VT-d and VT-x with Extended Page Tables, so compatible laptops can be used for virtualization when the operating system and firmware are configured appropriately. Intel also lists Trusted Execution Technology, Boot Guard, Control-Flow Enforcement Technology, Partner Security Engine, Threat Detection Technology and Standard Manageability.
Recommended Free Tools
Several business-management features are not supported on this SKU, including Intel Active Management Technology (AMT), Remote Platform Erase, One-Click Recovery, Total Memory Encryption–Multi-Key, the Stable IT Platform Program (SIPP), VT-rp and Virtualization Technology with Redirect Protection, and Virtual Device Management Device (VMD).
Organizations should check these omissions against their management and security requirements instead of assuming that every Core Ultra business laptop supports the same vPro-related features.
Who should choose a Core Ultra 7 258V laptop?
The 258V is a good fit for buyers seeking a thin laptop with integrated graphics, long-runtime-oriented power characteristics and local AI acceleration. It is suited to everyday productivity, browser-heavy work, office applications, video playback, coding and other workloads that benefit from a capable integrated GPU without requiring a separate graphics card.

It is less suitable when the priority is a workstation-class CPU, a high-power discrete GPU, user-replaceable memory or extensive internal expansion. In those cases, compare laptops with higher-power H or HX processors, a discrete GPU or standard socketed/replaceable system components.
When comparing actual products, inspect the complete laptop specification:
- Confirm whether it has 16 GB or 32 GB of memory, since the RAM is generally not upgradeable.
- Check the display resolution, refresh rate and panel type rather than relying on the processor’s maximum display specifications.
- Verify the number and type of USB-C, Thunderbolt, HDMI and external-display connections.
- Check SSD capacity and whether the storage drive can be replaced.
- Look for independent tests of sustained performance, battery life and fan noise.
- For business deployment, verify the exact manageability and security features required by your organization.
