CPU rumours: AMD Ryzen 7000X3D three times (almost) without clock loss


There are references to the Ryzen 7000X3D expected at CES 2023 via Twitter, i.e. those variants of the Zen 4 CPUs that are equipped with an additional L3 cache. Accordingly, three models are to be expected, which have 8, 12 or 16 cores.

The previously unconfirmed information comes from South Korean PC website Quasarzone and was shared via Twitter by @harukaze5719. While the predecessors only have the eight-core Ryzen 7 5800X3D (test) with a stacked additional cache aka 3D V-Cache, which provides a big performance boost for many games, the successors are said to have three models.

Expect a model with 8 cores (Ryzen 7 7700X3D/7800X3D?), a model with 12 cores (Ryzen 9 7900X3D?) and one with 16 cores (Ryzen 9 7950X3D?). Compared to the previous models without V-Cache, these should achieve the same or at least almost the same clock level. The Ryzen 7 5800X3D, on the other hand, works with a base clock reduced by 400 MHz and a boost clock that is 200 MHz lower than the Ryzen 7 5800X.

Benchmarks are only projections

The game benchmarks shown are only projections, where the performance difference from the Ryzen 7 5800X to the Ryzen 7 5800X3D was simply taken as the basis. The clock of the Ryzen 7 5800X was reduced to 4.4 GHz so that it works at the same clock as the 5800X3D.

A potential Ryzen 9 7950X3D would therefore achieve around 60 percent more FPS in Cyberpunk 2077 than the downclocked Ryzen 5800X. This would also narrowly beat the previously leading Intel Core i9 13900K. In two other games, however, the calculated Ryzen 9 7950X3D leads more clearly, as these benefit more from the additional L3 cache.

Start Radeon RX 7900 sluggish?

A sentence on the Radeon RX 7900 XT(X) expected on December 13 is also lost. According to Quasarzone, the initial inventory should be very low, but this could only affect the reference models. The partners' custom cards are not to follow until the end of the year.
