Processors with the new feature will arrive from the end of 2021
At the end of the conference AMD to Computex This year, the company’s CEO, Lisa Su, gave news of the development of a New technology to place SRAM perpendicular to Healer. This allowed a 64MB cache increase which resulted in مما 15% average gains in gaming performance.
a AMD This technology was developed in cooperation with TSMC Use TSVs (via Silicon – VIA) for the purpose of “Stack” 64 MB of SRAM directly on CCD, the height difference generated by this process is corrected by silicon and does not lead to significant changes in the final size or thickness Healer.

Lisa Su has yet to explain how this change altered the different CPU cache hierarchy, however, we do know that the total CPU cache goes up to 100MB, with 4MB L2, 32MB L3 plus 64MB of 3D vertical cache.
“We are taking this Ryzen 5000 processor and stacking 64MB of 7nm SRAM directly on top of each core collector, effectively Triple the amount of L3 cache running Zen 3 cores. 3D cache is Plugged directly into CCD From Zen 3 with Bi-directional silicone Send signals and power between stacked chips, with support for Bandwidth more than 2 terabytes per second. “

Lisa Sue showed a prototype of Ryzen 9 5900X With this new technology on display and also presented a comparison between the Ryzen 9 5900X without 3D cache and with the 3D cache in the Gears 5 benchmark. The larger amount and cache only brought a 12% increase in game performance, and this increase was greater in other scenarios, as shown in the event.

The CEO claims that in many games, new caching locating technology has increased on average 15% in performance Note, which may represent a margin for AMD to strengthen an advantage against Intel’s Rocket Lake-S architecture.

Lisa Su announced that this technology It will arrive at the end of 2021, which leaves us room to speculate that the 3D vertical cache will be the differential between potential Ryzen 6000 models, but we still don’t have any confirmation of that theory.
For more details on SRAM’s new “stacking” technology on top of the CCD processor, you can watch AMD’s presentation at Computex 2021 from the minute. 32:32When Lisa Su enters the stage to deliver the news.
