CPU Comparison
Intel Core i5-14600K vs Intel Core Ultra 5 245K
A side-by-side comparison of specs, performance and value. The Intel Core i5-14600K is a 14-core, 20-thread unlocked desktop processor that serves as the flagship of the i5 Raptor Lake Refresh lineup. Released in October 2023, it targets gamers and enthusiasts who demand high frame rates and robust multi-threaded performance without stepping up to the i7 tier. Operating at a 3.5 GHz base and boosting up to 5.3 GHz on the P-cores, it features 6 Raptor Cove P-Cores and 8 Gracemont E-Cores. The 20MB L2 cache and 24MB L3 cache ensure snappy performance in memory-sensitive games and applications. Built on the Intel 7 process, it natively supports DDR5-5600 and features 16 PCIe Gen 5 lanes. With a 125W base TDP and an unlimited PL2 power limit, it is designed to boost aggressively under load. While it lacks an included cooler, its fully unlocked multiplier allows for significant tuning, making it the definitive choice for mid-range overclockers and high-refresh-rate gamers aiming to maximize their system's potential.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Highly capable in multi-threaded workloads, though 8 P-cores on i7s pull ahead in heavy rendering.
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
Top-tier gaming performance that often matches or beats previous-gen i9s in CPU-bound scenarios.
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
Strong VM performance, but unlimited PL2 requires robust cooling for sustained loads.
Good for running multiple VMs with the 14-core configuration and high power budget supporting sustained multi-threaded loads.
Efficiency
Efficiency drops when pushed to its 253W extreme, requiring substantial cooling.
Significantly more efficient than previous-generation K-series processors like the 14600K, thanks to the 3 nm process, though 159W PL2 is still substantial.
