This Core Ultra 5 245K review is about a chip most people will overlook — and that is a shame. Sitting below the 265K in Intel’s Arrow Lake range, the 245K offers the same new architecture, the same efficiency gains and the same modern platform, at a price that works for a genuinely mid-range build.
It is not a headline grabber. It is something better for most buyers: the sensible middle of the range.
What you get
The 245K combines 6 performance cores with 8 efficiency cores, for 14 cores in total. It boosts to respectable speeds, includes the same built-in NPU as its bigger siblings, and runs on the LGA 1851 socket with DDR5 memory. You will need a new motherboard if you are coming from an older Intel platform, so remember to budget for the board.
In everyday use it is quick and responsive. Browsing, streaming, office work, photo editing and gaming all run without fuss. It is the kind of chip that does its job without drawing attention to itself — which, for a mid-range CPU, is exactly what you want.
Gaming performance
Paired with a mid-range graphics card, the 245K delivers smooth gaming at 1080p and 1440p. Esports titles run at very high frame rates, and demanding single-player games are comfortable at high settings. At 1440p, where the graphics card matters more, the 245K is effectively as fast as chips costing much more.
Compared with the Core Ultra 7 265K, you lose a few cores and a little speed, but save a meaningful amount of money. Compared with the Core i5-14600K, the older chip is slightly faster in some multi-threaded tasks but much hungrier for power. Our CPU benchmarks put all three side by side.
Efficiency is the point
The 245K’s real selling point is efficiency. Where a 14th-generation Intel chip of similar speed could draw a lot of power under load, the 245K sips it. A modest air cooler handles it easily, the PC stays quiet, and you do not need a high-wattage power supply.
For a first build, that matters more than it sounds. Every pound or dollar saved on cooling and power can go toward a better graphics card or a bigger SSD — parts that change the experience far more than a slightly faster CPU would. Our guide to choosing the right CPU makes the same point about balancing a build.
Productivity and multitasking
Fourteen cores make the 245K a capable worker. Photo editing, code compiling, streaming and running several applications at once are all comfortable. It will not match the 265K or a Ryzen 9 in long renders, but for the mixed use most people actually do — gaming in the evening, work during the day — it is more than enough.
The NPU handles AI features in Windows without loading the main cores, a small bonus today that may matter more as software catches up. See our Core Ultra 9 285K review for more on what the platform can do.
Who should buy the 245K?
- Builders putting together a mid-range gaming PC and wanting a modern, efficient Intel chip
- Anyone starting fresh who likes the LGA 1851 platform’s upgrade path
- People who value a quiet, cool PC over raw benchmark numbers
- Buyers who would rather spend the savings on a better graphics card
The verdict
This Core Ultra 5 245K review concludes that the mid-range Arrow Lake chip is one of the smartest buys in Intel’s current line-up. It is fast enough for almost any game, efficient enough to run cool and quiet, and priced for real-world builds. If you are building a new PC and want modern Intel without paying flagship prices, start here — and check our buying guides to finish the build around it.
