AMD Ryzen 7000 3D V-Cache Official: Ryzen 9 7950X3D 16-Core & 144 MB, Ryzen 9 7900X3D 12-Core & 140 MB, Ryzen 7 7800X3D 8-Core & 104 MB, Ryzen 7 7800X3D 8-Core & 104 MB, Set For February Launch
The AMD Ryzen 7000 CPUs with 3D V-Cache technology are the second generation of stacked cache consumer CPUs. The Zen 3 lineup featured a single 3D V-Cache SKU, but the Zen 4 lineup will include three SKUs at various price points.
AMD Ryzen 9 7950X3D has 16 cores and 144 MB of cache.
The AMD Ryzen 9 7950X3D, which will be the first 16-core CPU to feature 3D V-Cache technology, will be at the top of the lineup. The CPU has 32 threads, 144 MB cache (64 MB CCD, 64 MB V-Cache, and 16 MB L2), and a power consumption of 120W. It has a slower base clock speed of 4.2 GHz than the standard 7950X, but the boost clock speed is the same at 5.7 GHz. The slower base clock speed may account for the lower TDP of 50W compared to the non-3D version.
On the Ryzen 9 X3D CPUs, AMD implemented 3D V-Cache technology by placing the SRAM cache on a single core complex die (CCD) rather than both CCDs. This enables optimised gaming performance via a single CCD while also allowing for improved multi-threaded performance via the second die, which operates at higher clock speeds (1T). The goal is to achieve a balance of single-threaded gaming performance and multi-threaded application performance without sacrificing overall clock speeds as in previous generations. It will be interesting to see how the final retail units perform and how much customization the new CPUs allow.
AMD Ryzen 9 7900X3D has 12 cores and 140 MB of cache.
The AMD Ryzen 9 7900X3D has 12 cores and 24 threads and is the second CPU in the lineup. It’s a two-CCD setup, with one CCD featuring V-Cache and the other not. The CPU has a total cache of 140 MB (64 MB CCD, 64 MB V-Cache, and 12 MB L2). It has a 4.4 GHz base clock speed, which is 200 MHz slower than the non-3D SKU, and a 5.6 GHz boost clock speed. The CPU’s TDP is 120W.
AMD Ryzen 7 7800X3D Is The New Gaming Champ, Replacing The 5800X3D!
Finally, the Ryzen 7 7800X3D is the successor to the Ryzen 7 5800X3D. With 8 cores, 16 threads, and 104 MB of cache, this CPU is ideal for gamers (32 MB CCD, 64 MB V-Cache, and 8 MB L2). It has a base clock speed of around 4 GHz, which is at least 500 MHz slower than the Ryzen 7 7700X, and a boost clock speed of 5.0 GHz, which is 400 MHz slower.
The Ryzen 7 7800X3D retains its 120W TDP despite running at lower clock speeds than the AMD Ryzen 7 7700X, which has a TDP of 105W. This implies that the cache necessitates the extra TDP, and that AMD is optimising the base and boost clocks on the Ryzen 9 CPUs to meet the 120W target. In future testing, it will be interesting to see how the clock speeds vary across the dual Ryzen 9 CCD SKUs.
AMD claims that the Ryzen 7 7800X3D performs 30% better than the Ryzen 7 5800X3D. While the specific titles used for this comparison were not disclosed, and no information on the test settings or configurations was provided, if these results are correct, the Ryzen 7 7800X3D may be just as popular in the retail market as the Ryzen 7 5800X3D. The AMD Ryzen 7000 3D V-Cache CPUs will go on sale in February 2023.
