Leaked details around the AMD Ryzen 4000 are coming, which belongs to the Vermeer family, and which integrates the Zen3 microarchitecture manufactured on improved 7nm manufacturing process. The leaked data reveals the existence of a couple of models.

The first of them offers 8 cores and 16 threads, and from this it seems that there will be three variants that will run with Base / Turbo frequencies between 3.80 / 4.40 GHz and 4.00 / 4.60 GHz for other two models. This means that the top-tier model offers an extra 100 MHz in Base / Turbo frequencies compared to the Ryzen 7 3800X. We remind you that Zen3 at the same speed as a Zen2 would be at least 17% faster according to the latest rumors.

On the other hand we have a 16-core and 32 threads CPU marked at 3.70 / 4.60 GHz, which implies an extra 200 MHz in the Base frequencies compared to the Ryzen 9 3950X, but 100 MHz less in the Turbo frequencies, something that might be fixed in the final variant.

All these CPUs are still engineering sample phase (A0), so in their final version (A1) there may be changes in the speeds of the silicon, where generally, we might see same or higher frequencies.

AMD Vermeer first appeared in a leaked slide from Informatica Cero back in 2018:
