New details have emerged about AMD’s 4000 series lineup over on Igor’s Lab, including part names, clock speeds, and more for Vermeer and Renoir parts such as the Ryzen 5 4400G, Ryzen 3 4200G, and Ryzen 7 4700G.
Together with earlier leaks, we now have a better idea about AMD’s 4000 series lineup, with Renoir and Vermeer parts. For starters, we now know that Renoir features a higher FCLK compared to Matisse (Ryzen 3000 APUs). FCLK determines the clock speed at which the Infinity Fabric interconnect operates, and in this case, it’s been bumped up to 2000 MHz.
Vermeer BIOS entries also tell us a bit about individual Vermeer chips. We know, based on the ordering part numbers (OPNs) for different SKUs that an eight-core, sixteen-thread Vermeer part exists, and that it will max out at 4.6 GHz, with a 4 GHz base clock. This is good news as base clocks have finally been pushed above the 4 GHz mark: in the worst-case scenario, Ryzen 3000 parts drop below 4 GHz in multi-threaded workloads. We also see that a sixteen-core, thirty two-thread Vermeer part exists, maxing out at 4.6 GHz, but with a lower 3.7 GHz base clock. This appears to be the successor to the Ryzen 9 3950X. (https://cobblerexpress.com/) With IPC gains, this could make the prospective Ryzen 9 4950X a potent force, up against Comet Lake S.
