Key Differences

TDP
Core Ultra 5 245K:125W (PL2 159W)
Core i5-14600K:125W (PL2 181W)

What this means: TDP indicates cooling requirements and power draw. A 65W CPU works with basic air coolers, while 125W+ may need a high-end tower cooler or AIO liquid. Higher TDP chips often perform better but generate more heat and need better airflow.

Cache
Core Ultra 5 245K:26MB
Core i5-14600K:24MB

What this means: CPU cache (L2 and L3) acts as ultra-fast memory close to the cores. Larger caches reduce trips to system RAM, cutting latency. Games benefit heavily from large L3 caches - AMD's X3D chips with stacked V-Cache demonstrate up to 20% gaming FPS gains from cache alone.

Socket
Core Ultra 5 245K:LGA 1851
Core i5-14600K:LGA 1700

What this means: The CPU socket must match your motherboard exactly - AM5 for AMD Ryzen 7000/9000, LGA 1851 for Intel Arrow Lake. This locks you into a platform: AMD AM5 supports multiple CPU generations, Intel sockets typically support one or two.

Threads
Core Ultra 5 245K:14
Core i5-14600K:20

What this means: Simultaneous multithreading (SMT/Hyper-Threading) doubles the tasks each core can juggle. A 6-core/12-thread CPU handles background apps, Discord, and streaming alongside gaming much better than a 6-core/6-thread chip. Less impact in pure gaming where few threads are used.

Base Clock
Core Ultra 5 245K:4.2 GHz
Core i5-14600K:3.5 GHz

What this means: The guaranteed minimum clock speed under sustained full load. Higher base clocks provide more consistent performance during long rendering jobs or extended gaming sessions when boost clocks can't be maintained due to thermal limits.

Boost Clock
Core Ultra 5 245K:5.2 GHz
Core i5-14600K:5.3 GHz

What this means: The maximum single-core speed under ideal thermal and power conditions. This is the number that matters most for gaming FPS, as most games rely on 1-4 fast cores. Higher boost = snappier responsiveness and higher peak frame rates.

Architecture
Core Ultra 5 245K:Arrow Lake
Core i5-14600K:Raptor Lake

What this means: CPU architecture determines IPC (instructions per clock) - how much work gets done per MHz. Newer architectures are significantly faster at the same clock speed, and also bring feature support like AVX-512 and improved power efficiency. Zen 5 and Arrow Lake both deliver meaningful IPC gains over their predecessors.
