AMD unveils new 3D Cache technology that delivers up to 15% higher gaming performance

Processors with new features will come from the end of 2021

at the end of the conference amd for Computex This year, the company’s CEO, Lisa Su, hired A. presented news about the development of New technology to position SRAM vertically Processor. This allowed 64MB cache growth resulting in 15% average gain in gaming performance.

a amd Developed this technology in collaboration with TSMC using the TSVs (through-silicon-vias) for “Stack” of 64MB SRAM Directly on CCD, the height difference generated by this process was corrected by silicon and does not lead to a significant change in the final shape or thickness Processor.

Lisa Su has still not explained how this change may have changed the hierarchy of different CPU cache memory, however, we do know that the total CPU cache memory increases to 100 MB, 4 MB L2, 32 MB L3 Plus 64MB Vertical Cache in 3D .

“We’re taking this Ryzen 5000 processor and effectively stacking 64MB of SRAM on 7nm directly on top of each core complex Triple the amount of L3 cache powering our Zen 3 cores. have 3d cache Plugged directly into CCD with zen 3 double-sided silicone transmitting signal and power between stacked chips, with support Bandwidth of over 2TB per second. “

Lisa Su also showed a prototype of the A prototype Ryzen 9 5900X The presentation also presented a comparison between the Ryzen 9 5900X with and without 3D cache and 3D cache in the Gears 5 benchmark with and without this new technology. Only more amount and cash increased game performance by 12%, and this increase was even greater in other scenarios, as shown in the event.

CEO claims that in many games, new cash-positioning technology has increased average performance at 15% That could represent a margin for AMD to consolidate advantage against Intel’s Rocket Lake-S architecture.

Lisa Su announced that this technology will arrive at the end of 2021, which leaves room for us to speculate that 3D vertical cache will likely be the difference between the Ryzen 6000 models, but we still have no confirmation of this theory.

For more information on the new SRAM “stacking” technology on top of the processor CCD, you can watch AMD’s presentation at Computex 2021 from Minutes. 32:32, when Lisa Su enters the stage to present the news.
