It speeds up surprisingly much on the otherwise not very beefy graphics unit.
AMD’s Ryzen 7000 CPUs are interesting mainly because of the processor cores, but the systems also received a not very powerful IGP, which can be installed mainly for multimedia purposes and taking office needs into account. In fact, it can cover these areas, but the Ryzen 9 7950X3D equipped with 3D V-Cache technology noticed something interesting in PCMag.

According to the magazine’s test, 3D V-Cache also has a good effect on IGP, which may be due to a special operating mode. The IGP of the Ryzen 7000 CPUs has used the L3 cache of the CPU chips to some extent, because if the user does not use a dedicated GPU, the IGP will be the bottleneck during a game. That is, if an application runs on the integrated graphics controller itself, AMD can also use some L3 cache to speed up graphics calculations. It won’t help dramatically on a design without 3D V-Cache technology, but it’s still a little extra.

With 3D V-Cache, however, the situation changes, as there are many more caches available. On a related note, we’ve learned that this helps save tiling-related cache queues that get pushed out of the IGP’s own L2 cache, not necessarily into system memory, but into the processor’s L3 cache. It works a bit like Infinity Cache, only here the system does not belong exclusively to the graphics controller, but is forced to share with other processes as well. At the same time, 128 MB of L3 cache is such a large capacity that it can significantly boost the performance of a small IGP, especially if the memory bus is scarce.
By the way, even the system’s integrated graphic controller does not change the world at all, but it is a fact that 3D V-Cache offers a significant advantage on this front as well.
