AMD’s 3D V-cache can be used not only for CPU, but also for GPU

AMD has announced plans to release an updated version of Zen 3 with 3D V-Cache in early 2022. This is a process designed to stack caches vertically to greatly increase the available L3 cache, thereby significantly improving performance.Word comes from Tom’s hardware AMD is in development Register the technology as a trademark Cooperate with the United States Patent and Trademark Office. This alone has no special news value, but potential use cases for products other than the CPU are mentioned in the application. It is worth noting that the GPU.

When the facts proved that its RX 6800 series and Nvidia’s high-end products are very competitive, AMD was taken aback. It managed to achieve this goal with a 256-bit bus that many people consider mediocre, which provides relatively limited memory bandwidth. The reason AMD includes a 256-bit bus is to include what it calls an infinite cache. The 128MB cache of the Navi 21 GPU is an important reason why AMD is still competitive in performance despite the bandwidth disadvantages. The cache acts as on-chip storage, reducing the need to access VRAM. If 128MB is beneficial, then assuming AMD can extend its V-Cache technology to its GPU products, Infinity Cache of 256MB or 512MB or more can produce some pretty significant performance improvements.
