Performance Compared

Productivity

Intel Core Ultra 5 245KF80

14 cores provide good multi-threaded performance, though the 8 E-Cores are outpaced by the 250KF Plus's 12 E-Cores in heavily parallel workloads.

Intel Core Ultra 5 250K PlusBest87

18 cores deliver strong multi-threaded performance. The iGPU can accelerate video encoding in supported applications, providing a small productivity edge over the KF variant.

Gaming

Intel Core Ultra 5 245KF83

Strong 1080p and 1440p gaming performance with the 5.2 GHz boost. Pairs well with GPUs up to RTX 4070 class without significant bottlenecks.

Intel Core Ultra 5 250K PlusBest85

With a discrete GPU, gaming performance is identical to the 250KF Plus — excellent at 1080p and 1440p. The iGPU can handle eSports titles at 720p/1080p low for troubleshooting or casual play.

Efficiency

Intel Core Ultra 5 245KF72

Better idle and light-load efficiency than 13th/14th Gen due to the 3nm compute tile, but 125W/159W power limits are substantial.

Intel Core Ultra 5 250K PlusBest75

Standard 125W/159W power profile for Arrow Lake desktop. The 3nm compute tile helps at idle and light loads, but full-load power is substantial.

Our Verdict on Each

A solid Arrow Lake processor that was reasonably priced at launch but has been made largely redundant by the 250KF Plus, which offers more cores, higher clocks, and faster memory support for $110 less.

Best for: Only if found at a significant discount (under $200) compared to its $294 MSRP.

Read the full review

The 250K Plus might be the best all-around value in Intel's entire desktop lineup. For just $15 over the KF variant, you get a fully functional iGPU, 18 cores, an unlocked multiplier, and DDR5-7200 support. It eliminates every excuse not to build on Arrow Lake.

Best for: Building a new desktop where you want the safety net of integrated graphics, maximum cores per dollar, and the option to overclock — all without breaking the bank.
