Intel’s Core Ultra 5 250K Plus and Core Ultra 7 270K Plus are Arrow Lake desktop refresh processors announced for retail availability beginning March 26, 2026. Both add four efficiency cores over the earlier 245K and 265K, respectively. Intel also advertises gaming gains, but those figures come from its own limited six-game tests—not an independent, broad comparison—so buyers should weigh them alongside current CPU prices and the cost of an LGA 1851 build.
What Intel changed in the Core Ultra 200S Plus refresh
The 250K Plus and 270K Plus refresh Intel’s Arrow Lake desktop line. Their clearest specification change is a higher core count: Intel says each has four more efficiency cores (E-cores) than the previous-generation model it uses for comparison. Intel also states that die-to-die frequency is up by as much as 900 MHz versus the 245K and 265K. That is Intel’s specification comparison, not a guarantee of a particular application or gaming uplift.
| Processor | Core configuration | Intel comparison model | Launch suggested price |
|---|---|---|---|
| Core Ultra 5 250K Plus | 18 cores: 6 performance cores (P-cores) + 12 E-cores | Core Ultra 5 245K; four fewer E-cores | $199 starting price announced by Intel in 2026 |
| Core Ultra 7 270K Plus | 24 cores: 8 P-cores + 16 E-cores | Core Ultra 7 265K; four fewer E-cores | $299 starting price announced by Intel in 2026 |
Intel announced the processors and said retail partner availability would begin March 26, 2026. Availability and actual selling prices depend on retailer and date; the announced starting prices are not live street-price quotes. Intel’s product specification page lists a $339–$349 recommended customer price for the 270K Plus when accessed in 2026, a separate price reference rather than a guaranteed retail price: Intel Core Ultra 7 270K Plus specifications.

Intel claims the 270K Plus is up to 15% faster in gaming, on a geomean basis, than the 265K; its claimed geomean gain for the 250K Plus over the 245K is 13%. The figures come from Intel’s own comparisons of six selected games per processor pair, run at 1080p with High settings and with Intel Binary Optimization Tool enabled where supported. Intel used different game selections for the two comparisons, so the percentages should not be treated as a direct comparison between the 250K Plus and 270K Plus. They are vendor measurements, not independently established results: Intel’s launch announcement and performance disclosures.

- Robust Power & Thermal Design: Engineered with 125W base power and 250W max turbo power to sustain high‑intensity
Intel VP Robert Hallock described the chips in the launch announcement as offering “incredible performance and value for enthusiasts,” and claimed “up to 103% better multithread performance compared to competing CPUs in their segments.” That is promotional language from Intel, and the comparison should be read with Intel’s test conditions and qualifications—not as proof that either processor leads every competing CPU or workload.
Do not combine Intel’s six-game geomeans with another reviewer’s results from a differently configured test suite as if they were one controlled test. A useful independent comparison needs matching games, resolution, graphics settings, processor power settings and test conditions. The available evidence does not establish a universal winner against AMD or a broad, current independent ranking across these processors.

Which processor makes more sense for your workload?
Choose by the work you actually do
The 270K Plus has more total cores and more P-cores than the 250K Plus, while both add four E-cores over their respective predecessor models. That makes core configuration a relevant specification when considering heavily threaded work, but core count alone does not establish how much faster a particular creation or productivity task will run. For gaming, use independent results from comparable tests rather than assuming the larger model’s core count or Intel’s generation-over-generation claim settles the choice.
- Mostly gaming: Compare independent gaming tests for the games and graphics settings you use, then check whether the price difference is worthwhile for your system.
- Creation or other multithreaded work: Look for benchmarks of your actual software; Intel’s launch comparison does not provide a universal result for every application.
- Mixed use: Balance relevant gaming and application results against the current CPU price and total platform cost, rather than choosing on core count alone.
Check the price you can actually buy at
Intel’s $299 and $199 figures were announced starting suggested prices for the 270K Plus and 250K Plus, respectively. The separate $339–$349 recommended customer price on Intel’s 270K Plus product page is not a retail quote. The sources do not establish live October 2026 prices or stock, so check retailers for the price available to you before comparing value.

Platform and upgrade considerations
The refresh uses Intel’s LGA 1851 socket. Intel’s performance disclosure identifies a Z890 motherboard in its test setup, but that does not establish that every LGA 1851 board supports both processors out of the box. Before buying, check the exact motherboard’s CPU support list and any required BIOS version. The socket and Z890 test setup are also noted in GamersNexus’ coverage of the Arrow Lake refresh.

- Performance Unlocked Up to 5.7 GHz unlocked. 40MB Cache
- Compatibility Compatible with Intel 800 series chipset-based motherboards
- Upgrading an existing system: If you already have a compatible LGA 1851 motherboard and DDR5 memory, verify processor support and BIOS requirements before assuming you can reuse the board. Include any parts you must replace in the upgrade cost.
- Building a new PC: Compare the complete cost of the processor, compatible LGA 1851 motherboard and DDR5 memory. A CPU-only price comparison can make one option look better while hiding a more expensive platform total.
How to make a buying decision
- Identify the applications and games that matter most to you.
- Find independent benchmarks that test the 250K Plus and 270K Plus under comparable conditions for those workloads.
- Check current retailer prices for the processors; do not treat Intel’s announced starting prices or recommended customer price as guaranteed selling prices.
- Add the motherboard and DDR5 memory costs for a new build, or confirm support and BIOS requirements for a motherboard you plan to reuse.
- Choose the processor whose tested performance and full system cost suit your needs; the available evidence does not support a universal winner across all workloads or against AMD.
