3D V-Cache
3D V-Cache is AMD's technique of stacking extra L3 cache vertically on top of the CPU die, which particularly benefits games.
Cache is small, very fast memory sitting between the CPU cores and system RAM. When the data a core needs is already in cache, it avoids a much slower trip to RAM.
Rather than widening the die to fit more cache, AMD stacks an additional layer on top of it. This raises total L3 cache substantially without a proportional increase in die area.
Games benefit more than most workloads because they repeatedly access the same working set — world state, physics, draw call data — which fits better in a larger cache. Productivity workloads that stream through large amounts of unique data see less gain.
