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: 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.
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 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: 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.
