AMD surprised everyone during its Computex 2021 keynote today by demonstrating the first 3D stacked vertical cache called 3D V-cache. AMD showed a 192 MB 3D V-cache (64 MB per CCD) implemented successfully on the Ryzen 9 5900X. The 3D V-cache brings several improvements over conventional 2D and microbump 3D packaging and was demonstrated to yield up to 15% performance gains in today's games with the current 7 nm Zen 3 architecture.
