CPU Comparison

Intel Core Ultra 5 235A vs Intel Core Ultra 5 245KF

A side-by-side comparison of specs, performance and value. The Intel Core Ultra 5 235A is a mid-2025 refresh of the Arrow Lake-S desktop lineup, offering 14 cores with a notably higher 3.4 GHz base clock compared to the T-series 235T. Built on TSMC's 3 nm process with a B0 stepping, the 235A delivers more consistent sustained performance by matching its PL1 power limit to its 65W TDP, eliminating the aggressive power throttling that characterizes T-series models. It retains the same 6 Lion Cove P-cores and 8 Skymont E-cores, the same 24 EU Arc Xe-LPG integrated GPU, and the same 13 TOPS NPU 3. The B0 stepping suggests manufacturing refinements that may improve voltage behavior, thermal characteristics, or silicon health compared to the earlier A0 stepping found on launch-day processors. Priced at $269 and released on July 29, 2025, the 235A fills the gap between the budget-oriented 225F and the higher-end 245T, targeting mainstream users who want reliable sustained performance from Arrow Lake without paying for K-series features or accepting T-series power constraints.

Performance Compared

Productivity

Intel Core Ultra 5 235A80

Sustained 65W power delivery allows the 14 cores to maintain higher frequencies during extended rendering and compilation tasks.

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.

Gaming

Intel Core Ultra 5 235A83

The higher base clock translates to more consistent frame rates compared to the 235T, especially in longer gaming sessions where T-series would throttle.

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.

Virtualization

Intel Core Ultra 5 235A78

Adequate for running several VMs simultaneously with the 65W sustained power budget providing stable performance.

Intel Core Ultra 5 245KF

Efficiency

Intel Core Ultra 5 235ABest83

Good efficiency at 65W sustained, though not as extreme as the T-series. The 3 nm process keeps power per watt competitive.

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.
