Amd's zen cpu prototype offers a 15% increase in gaming and will be in production "by the end of the year"

After announcing its mobile GPUs, Zen 3 APUs and some tasty details about FidelityFX Super Resolution, AMD ended its Computex keynote revealing its new 3D chip technology. True, this is not something that usually excites you too much, only this is quite tidy and able to produce a seemingly significant increase in performance for games.

3D chiplet technology allows circuits to be stacked on top of each other. AMD showed what was possible with the technology using an example of 3D vertical cache, or 3D cache, where the cache is placed on top of the existing silicon. Doing some downright crazy cache capabilities.

Dr. Lisa Su showed off the new technology using a prototype Ryzen 9 5900X which had a frankly impressive L3 cache of 192 MB in total. Yes, you read that right, 192 MB. The current version of the chip is 64 MB, which is still considered more than healthy for a modern CPU, although this prototype is three times larger.

The additional cache is located at the top of the chip and connects to it with TSV (via silicon channels), the sites of which appear to be in Zen 3 silicon since it was released if this tweet from Andreas Schilling it’s anything to go by.

One thing AMD discovered with its Zen 3 architecture is that games love a lot of low-latency local cache. Throwing more stuff at the chips should logically result in high performance and safe enough, this is exactly what Dr. Lisa Su showed at Computex, with this 5900X prototype achieving 206 fps at 1080p on Gears V, while the normal chip delivered 184 fps. This means a 12% increase in performance without the need for a complete architectural redesign.

AMD then showed increased performance in five games with the new 3D cache compared to the current model, and on average 15% of those titles are watched, with Monster Hunter World achieving substantial improvement. of 25%. All at 1080p and all with chips locked at 4 GHz for easy comparisons.

Not bad considering that it’s basically the same architecture as the current Ryzen 5000 chips, albeit with new packaging to increase the amount of cache. In fact, AMD has tested this new chip in 32 games in total to get this final 15% increase, which is a good sign that this is a consistent and representative improvement and not just based on a handful of selected titles.

Does 3D V-cache technology work, though, when will we see it? Rather than one might think. Dr. Lisa Su ended her talk by saying, "In fact, we have made great strides in the overall development of this technology and will be ready to begin production of our higher-end products with 3D chips by the end of the year." ;this year. "

AMD has reportedly removed its Warhol update, which could mean it is preparing to release 3D cached versions of its existing chips for a blatant 15% improvement in gaming. This is not exactly a bad idea and could represent a real response to Intel's Alder Lake, which also promises big game improvements and is released before the end of the year.
