Performance Compared

Productivity

Intel Core i5-14600KBest88

Highly capable in multi-threaded workloads, though 8 P-cores on i7s pull ahead in heavy rendering.

Intel Core Ultra 5 245K85

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 i5-14600KBest93

Top-tier gaming performance that often matches or beats previous-gen i9s in CPU-bound scenarios.

Intel Core Ultra 5 245K88

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 i5-14600K82

Strong VM performance, but unlimited PL2 requires robust cooling for sustained loads.

Intel Core Ultra 5 245K82

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

Efficiency

Intel Core i5-14600K70

Efficiency drops when pushed to its 253W extreme, requiring substantial cooling.

Intel Core Ultra 5 245KBest82

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