Performance Compared

Productivity

Intel Core Ultra 5 24578

Solid multi-threaded performance from 14 cores, though the 65W power limit reduces sustained throughput compared to 125W siblings.

Intel Core Ultra 5 245KFBest80

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.

Gaming

Intel Core Ultra 5 24572

Handles 1080p gaming adequately when paired with a mid-range discrete GPU, but the lower clocks compared to K-series parts limit frame rates in CPU-bound titles.

Intel Core Ultra 5 245KFBest83

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

Efficiency

Intel Core Ultra 5 245Best88

Excellent performance-per-watt thanks to the TSMC 3nm compute tile and conservative power limits.

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 245KF

Our Verdict on Each

A sensible locked Arrow Lake chip that trades peak frequency for a modest 65W power envelope, making it ideal for small form factor builds and users who prioritize efficiency over overclocking headroom.

Best for: Building a compact, quiet, power-efficient desktop with modern features like NPU and PCIe 5.0 without paying K-series prices.

Read the full review

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.
