AMD’s preliminary Zen CPU provides 15% more gaming power and is expected to be available at the end of this year

Chips with massive caches will be available prior to the close of the year.

3D chipset technology permits circuits to be stacked with one another. AMD demonstrated what was possible with this technology, using an illustration of 3D vertical caches, also known as 3D V-cache. In this case, storage for cache memories is stacked on top of the silicon. This creates some genuinely remarkable capacity for caches.

Dr. Lisa Su showed off the new technology using a model Ryzen 9 5900X, which had an astonishing 192MB of L3 cache. Yes, you read it right that’s the 192MB cache is a staggering amount. This version only has 64MB of memory, which is healthy for a modern CPU, but this model is three times larger.

The additional cache is on the top of the chip and connects to it using the TSVs (through-silicon vias)–the sites seem to have been located on Zen 3 silicon. Zen 3 silicon was first introduced if this tweet from Andreas Schilling is something to be believed.

AMD has discovered through the release of its Zen 3 architecture that games enjoy a lot of low-latency caches locally. Injecting more of this on its chips will logically boost performance. And sure enough, this is precisely what is what Dr. Lisa Su showed at Computex and the 5900X model delivering 206 frames per second in 1080p in Gears V and the standard chip produced 184fps. It’s an increase of 12% in performance, but without the need for the complete redesign of the architecture.

AMD followed up to demonstrate the increase in performance over five games using the 3D V-cache model compared to the old version. On average, you’ll see a rise of 15% improvement across these titles, with Monster Hunter World managing a significant increase of 25. All at 1080p and all with the chip clocked at 4GHz, making comparisons simple.

It’s not too bad since this is the same technology used in the Ryzen 5000 chips of today, however, with a brand new package to increase the cache size. In actuality, AMD has tested this new chip in 32 games to see that 15% boost, which is a positive indicator that this is a reliable, consistent improvement and not made up of a handful of games that have been picked from the list.
The 3D V-cache technology does work, but when will we be able to see it? It’s sooner than you think. Dr. Lisa Su finished her keynote with a statement, “We’ve made massive progress in the overall advancement of this technology, and we’ll have the ability to begin manufacturing our top-of-the-line products using 3D chips before the end of the year.
AMD is believed to have removed its Warhol refresh. This could mean it’s gearing up to launch 3D V cache versions of its chips that promise a jolly 15% performance improvement in games. This isn’t the best idea, but it could be a viable alternative for Intel’s Alder Lake, which promises significant improvements in gaming. It’s scheduled to be released by the time of the year-end.
