CPU Comparison

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

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 245KBest85

14 cores with 159W power headroom handle demanding productivity workloads well, though it sits below Core Ultra 7 and 9 models in heavily threaded tasks.

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 245KBest88

The 5.2 GHz boost and strong IPC of Lion Cove deliver excellent gaming performance, particularly at 1080p where CPU limits are most apparent.

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 245KBest82

Good for running multiple VMs with the 14-core configuration and high power budget supporting sustained multi-threaded loads.

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 245K82

Significantly more efficient than previous-generation K-series processors like the 14600K, thanks to the 3 nm process, though 159W PL2 is still substantial.
