AMD Ryzen 9 7950X3D, Ryzen 9 7900X3D, and Ryzen 7 7800X3D Zen 4 V-Cache CPUs Rumored to Debut at CES 2023


AMD is rumored to launch three new Zen 4 V-Cache CPUs, Ryzen 9 7950X3D, Ryzen 9 7900X3D, and Ryzen 7 7800X3D at CES 2023.

AMD prepares three Zen 4 V-Cache CPUs, Ryzen 9 7950X3D, Ryzen 9 7900X3D and Ryzen 7 7800X3D, for CES 2023, alleges rumor

The latest rumor about Zen 4 V-Cache parts comes from greymon55 who has come up with a cryptic tweet referring to the Ryzen 7000 3D V-Cache CPUs. According to the tweet, three Ryzen 3D V-Cache CPUs have been rumored, Ryzen 9 7950X3D, Ryzen 9 7900X3D, and Ryzen 7 7800X3D. Based on the SKUs, it looks like AMD will be targeting the high-end market with V-Cache chips and major V-Cache parts could hit retail later on.

We don’t know what kind of SRAM (3D V-cache) stacks will be featured in Zen 4 parts. Last generation Zen 3 V-Cache processors like the Ryzen 7 5800X3D featured a single Zen 3 CCD with 64MB of LLC stacked vertically on top of the die. For the Ryzen 7 7800X3D, this may also be true as it will feature a single Zen 4 CCD with 8 cores and 16 threads. However, the Ryzen 9 7950X3D and Ryzen 9 7900X3D will be with two Zen 4 CCDs since they pack 12 cores and 16 cores each, respectively. We still can’t say for sure if AMD will have a single CCD stacked with a 3D cache stack or if both Zen 4 CCDs will be stacked. It also remains to be seen if AMD retains the 64MB cache stack or changes it.

In any case, if AMD opts for the existing 64MB SRAM (3D V-Cache) stack, we’ll get up to 104MB of cache on the Ryzen 7 7800X3D, up to 140MB of cache on the Ryzen 9 7900X3D, and a whopping 144MB of cache. . MB of cache on the Ryzen 9 7950X3D. That’s a 2.6x increase over the Ryzen 7 7700X, an 85% increase over the 7900X, and an 80% increase over the Ryzen 9 7950X. More importantly, it appears that AMD has reserved the 7800X SKU for the 3D variation.

As for what this would mean for overall performance improvement, particularly in gaming, the AMD Ryzen 7 5800X3D has already shown that 3D V-Cache is a very viable upgrade in AAA titles and Ryzen 7000 CPU without V-Cache they’re already approaching or exceeding gaming performance on the 5800X3D. With 3D V-Cache, we can see an additional 10-15% gain across multiple titles on average. Workload performance-wise, the chips may perform just like existing parts, but may come with lower clock speeds. AMD said that future V-Cache CPUs could allow overclocking and we saw with the 5800X3D that it allowed some extension to overclocking and undervolting.

The leaker further claims that the announcement of AMD Ryzen V-Cache parts is expected at CES 2023, so we have to wait 4-5 months before we can see them in action. amd had previously mentioned That we’ll see parts of V-Cache in action later this year, but it looks like they’ve settled for CES 2023 for now.
