The new AMD Radeon PRO W6400 workstation GPU is based on the Navi 24 GPU which is made on the 6nm TSMC process node, the first in workstation GPU on 6nm, with 4GB of GDDR6 on a 64-bit memory bus. The Navi 24 GPU has 768 Stream Processors, so you won't be taking this into your work at Pixar and booting up your dailies, but the Radeon PRO W6400 is here.

AMD is only providing 4 x PCIe 4.0 lanes wired to the GPU, even though the Radeon PRO W6400 workstation card arrives with a full-sized PCIe 4.0 slot. The new Navi 24-based Radeon PRO W6400 workstation GPU slots under the higher-end Apple Max exclusive Radeon PRO W6000X series -- as well as the Navi 21-powered W6800, Navi 23-based W6600, and Navi 24-based W6400 -- the new Navi 24 GPU skips over the Navi 22, which we might eventually see later in the year.

We should expect GPU clocks on the Navi 24 GPU to reach around 2300MHz, offering up 3.5 TFLOPs of FP32 compute performance.
