At CES 2022, AMD launched a Zen 3 architecture desktop processor with 3D vertical cache (3D V-Cache) technology, brings an additional 64MB of 7nm SRAM cache to each CCD, the L3 cache capacity of the processor is increased from 32MB to 96MB, and the capacity is tripled. However, unlike past rumors, AMD only has an 8-core 16-thread Ryzen 7 5800X3D in the consumer market, and there is no Ryzen 9 5900X3D or Ryzen 9 5950X3D.

With the recent BIOS update by motherboard manufacturers, many AM4 motherboards have supported Ryzen 7 5800X3D, but they are still missing. Recently, Twitter user @greymon55 revealed that the Ryzen 7 5800X3D has begun to ship, and the first retail version may be available at the end of March. Recently, Intel has gradually rolled out the 12th generation Core series processors, which has recovered a lot of client markets, the Ryzen 7 5800X3D is AMD’s few countermeasures in the first half of 2022.

At the just-concluded ISSCC 2022, AMD also shared more details on the 3D V-Cache design. The demonstration document shows that the SRAM of 3D V-Cache is manufactured by TSMC N7 process, and the overall size is 41 square millimeters, supported by two additional CCD structures to assist the heat dissipation. To allow each core of the processor to communicate with the 3D V-Cache, AMD implemented a shared ring bus design at the L3 level, with the entire L3 cache available to each core. Although not integrated on CCX, it is likely to be in line with the speed of the native L3 cache.

It was previously reported that TSMC’s 3D SoIC technology is still in its infancy. Although its 7nm process node has a very high yield rate, the addition of 3D V-Cache technology has affected production efficiency. Compared with Vermeer-X, AMD is more concerned about the EPYC processor code-named Milan-X at this stage. Considering that these server processors require more CCDs, regardless of market demand or profit, AMD will also give priority to the server product line when production capacity is limited.
