AMD Radeon PRO W6400 is the Latest Workstation GPU From AMD Built On A 6nm Process

For the last few weeks, rumors about a new high-end Radeon PRO graphics card have been floating around and AMD even teased a new Radeon PRO GPU announcement for 19th January a couple of days ago. However, contrary to everyone’s speculation, the GPU launching today is far from the ultra-premium card that was expected, instead it’s a new entry-level workstation offering built on TSMC‘s 6nm process node.

AMD has just announced the Radeon PRO W6400. An OEM-only workstation GPU, just like its gaming contemporary, the RX 6400. The card is built using a Navi 24 GPU, but a cut-down version of it as it only features 768 Stream Processors which is the same as the Radeon RX 6400. As for the memory, the card features 4GB of GDDR6 VRAM across a 64-bit wide bus. 

Moreover, it has a 50W TDP, putting it well in line with the PCIe slot’s 75W spec. Speaking of which, only 4 of the 16 PCIe 4.0 lanes are actually wired to the GPU, something that can cause performance issues with PCIe Gen3 systems. The last known bit about the W6400 is its boost clock, which is around 2300Mhz, giving the card a full 3.5 TFLOPs of FP32 compute power. The card follows the footsteps of the recently-announced RX 6500 XT to become the first Radeon PRO GPU to utilize a 6nm process (from TSMC).

Not much else about the GPU is known at the moment, the details are sparse because in-depth reviews of the card are supposed to give live later today or early tomorrow. Hopefully, the encoding/decoding abilities of the card, along with the price are revealed as soon as possible. Being a workstation GPU, those details are quite important. This also means I don’t think I need to tell you that this card is not meant for gaming. It will likely perform even worse than the actual RX 6400 if you tried to push it that way.
