There are few CPUs that offer the reputation that the AMD Ryzen 7 9800X3D. Until very recently, it was the fastest CPU for gaming in the world, and it's still our best pick overall. This 8-core, 16-thread processor features AMD's newest Zen 5 architecture and comes equipped with a boost clock speed of up to 5.2 GHz.The performance upgrade, however, is really noticeable in one area: the cache. These 3D V-cache chips feature a boosted 96MB L3 cache capacity, stacked beneath the CPU cores, closer to the integrated heat spreader on a reconfigured die.
