AMD Ryzen 9 7950X3D, Ryzen 9 7900X3D, Ryzen 7 7800X3D - official presentation of Zen 4 processors with 3D V-Cache packaging technologyThis year’s AMD conference at CES 2023 was full of various announcements. In the previous material, we have already described in detail the AMD Ryzen 7040 and Ryzen 7045 mobile processors from the Phoenix APU family and the Dragon Range CPU. As we expected, there was no official announcement of Ryzen 7000X3D desktop processors at the fair. Unlike the previous generation, this time three systems with 3D V-Cache were introduced: Ryzen 9 7950X3D, Ryzen 9 7900X3D and Ryzen 7 7800X3D. There was also some very interesting information about the specification of Zen 4 chips.

AMD has officially announced the Ryzen 9 7950X3D, Ryzen 9 7900X3D and Ryzen 7 7800X3D processors. Zen 4 chips with 3D V-Cache will be available starting February 2023 and offer up to 144MB of L3 cache.

AMD officially presented the AMD Ryzen 9 7950X3D, Ryzen 9 7900X3D and Ryzen 7 7800X3D processors. All processors will debut on sale in February, but details on prices have not yet been shared. Zen 4 systems with 3D V-Cache in the case of Ryzen 9 7950X3D and Ryzen 9 7900X3D are characterized by the same Turbo timing, reaching 5.7 GHz and 5.6 GHz, respectively. The base clock is lower, at 4.2 GHz for Ryzen 9 7950X3D (down 300 MHz) and 4.4 GHz for Ryzen 9 7900X3D (down 300 MHz). However, these changes resulted in a significant reduction in the TDP factor, which is 120W instead of 170W. All three Zen 4 chips with 3D V-Cache will receive an additional 64MB of L3 memory, but the additional memory was applied to only one chiplet, regardless of the what kind of processor are we dealing with. Thus, AMD Ryzen 9 7950X3D and Ryzen 9 7900X3D offer 128 MB of L3 cache each (144 MB and 140 MB in total, respectively), while Ryzen 7 7800X3D has 96 MB of L3 cache (with L2 it is already 104 MB in total).

Changes will also come to the 8-core AMD Ryzen 7 7800X3D processor – the manufacturer has only announced a Turbo clock of 5.0 GHz – this is 400 MHz less than the Ryzen 7 7700X. At the same time, the base clock is still being refined, but it is to be higher than that of the Ryzen 7 7700X (so at least 4.6 GHz). The TDP of this system is also 120 W, so it is 15 W higher compared to the basic version of Zen 4. Interestingly, AMD has also lowered the maximum allowable temperature. For Raphael systems without 3D V-Cache, it was 95 degrees, while for models with 3D V-Cache, the maximum temperature was 89 degrees. Unfortunately, performance has not been specifically discussed, although we know that Ryzen 7 7800X3D is to be up to 30% more efficient in games compared to Ryzen 7 5800X3D, while Ryzen 9 7950X3D is to be 9 to 24% more powerful compared to Intel Core i9-13900K , depending on the specific games that respond better or worse to the increased L3 cache.
