Key Differences
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.
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.
What this means: More cores handle multi-threaded workloads like video editing, 3D rendering, streaming while gaming, and running VMs. Most games plateau at 6-8 cores - extra cores rarely help gaming FPS but matter enormously for productivity. 4 cores is entry-level, 6-8 is the gaming sweet spot, 12+ is for heavy multitasking.
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.
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.
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.
What this means: Budget and mid-range CPUs often include a stock cooler, saving you $20-40. Stock coolers are adequate for basic use but run louder and hotter than aftermarket options. High-end CPUs never include coolers - factor that into your total build cost.
