AMD isIt seems that they may be considering the 3D V-Cache version of the Radeon RX 7000 series.of foreign mediaTom’s Hardwarereported.
semiconductor engineerMr. Tom Wassicktook an infrared look inside the die of the Radeon RX 7900 XT and found the same type of 3D V-Cache splice points used in the Zen 4 architecture.
Wassick doesn’t say whether these TSV junctions are specifically used for caching purposes. However, I haven’t heard of AMD’s plans to use such junction points in any non-cache 3D package so far. From this, it seems that it is prepared to improve game performance or calculation performance.
3D V-Cache has been used in Ryzen and EPYC CPUs with great success. How 3D V-Cache works on GPUs is unknown, but in theory it should be able to handle cache-sensitive workloads faster.
If AMD is considering adding 3D V-Cache to their GPUs, that would be pretty cool. It may be the next step to improve game performance.
