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 250KF PlusBest86

18 cores provide impressive multi-threaded performance for the price, handling video encoding, compilation, and multitasking workloads effectively.

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 250KF PlusBest85

The 5.3 GHz boost and strong IPC deliver excellent gaming performance at 1080p and 1440p. Pairs well with mid-to-high-end GPUs without creating bottlenecks.

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 250KF PlusBest75

The 3nm compute tile helps, but 125W base and 159W PL2 are substantial for a budget chip. Still more efficient than comparable AMD offerings at full load.

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

An extraordinary value proposition that packs 18 Arrow Lake Refresh cores with an unlocked multiplier into a $184 package. The lack of integrated graphics is a non-issue for most discrete GPU buyers, making this one of the best budget desktop CPUs available.

Best for: Building a new gaming or productivity PC on a budget where every dollar counts and you already plan to use a discrete GPU.
