AMD Radeon Pro W6800 based on Navi 21 to offer 32 GB GDDR6 VRAM, takes on the NVIDIA Quadro GV100 in Geekbench OpenCL leak

The AMD Radeon Pro W6800 has surfaced on the Geekbench 5 OpenCL database. The Radon Pro W6800 is based on the same Navi 21 GPU as the consumer Radeon RX 6800 but offers 32 GB RAM and, apparently, much higher clocks. The OpenCL results of the Radeon Pro W6800 show significant improvements over the W5700 series and seem to be on par with an NVIDIA Quadro GV100.

AMD will announcing its first RDNA 2 workstation cards later today. One of the cards in the lineup is the Radeon Pro W6800. We do not yet know details of the Radeon Pro W6800, but a new Geekbench entry (now taken down) points to some interesting specifications.

According to the Geekbench 5 OpenCL entry, the Radeon Pro W6800 is based on the Navi 21 GPU with 3,840 stream processors (SPs). Geekebench identifies the number of compute units (CUs) as 30, but that could be due to the driver considering a workgroup processors (WGP) equivalent to a CU. A WGP on an RDNA GPU is actually equivalent to two CUs i.e. 60 CUs on a consumer Radeon RX 6800.

The interesting information we see here is that the Radeon Pro W6800 is endowed with 32 GB GDDR6 VRAM, which is twice that of consumer Navi 2x cards. We also see the benchmark listing the clock speed at 2,554 MHz, which seems high for a workstation card with a blower-style cooler; workstation cards normally run at lower clocks and TDPs to ensure longer life. 

Coming to the benchmark itself, we see that the Radeon Pro W6800 scores 137,230 points. This is a significant performance uplift from the Radeon Pro W5700 (68,400) and Radeon Pro W5700X (73,656) and is only about 1.8% slower than an NVIDIA Quadro GV100 (139,722) as per official Geekbench 5 OpenCL records. The W6800 seems to be about 7.4% faster than the consumer Radeon RX 6800 (127,724). Though impressive, these numbers must be taken with a pinch of salt for now considering early drivers and the questionable applicability of the benchmark itself for testing workstation cards. 

According to an official tease from AMD, the Radeon Pro W6800 will feature six mini-DisplayPort 1.4 connectors that can support six 4K60 monitors (or three 5K60 or one 8K60). However, we do not see a USB-C port as was the case with the Radeon Pro W5700. The Radeon Pro W6800 will also support AMD Eyefinity for combining multiple displays as a single desktop and SR-IOV to power multiple remote workstations.

Though a cell and molecular biologist by training, I have been drawn towards computers from a very young age ever since I got my first PC in 1998. My passion for technology grew quite exponentially with the times, and it has been an incredible experience from being a much solicited source for tech advice and troubleshooting among family and friends to joining Notebookcheck in 2017 as a professional tech journalist. Now, I am a Lead Editor at Notebookcheck covering news and reviews encompassing a wide gamut of the technology landscape for Indian and global audiences. When I am not hunting for the next big story or taking complex measurements for reviews, you can find me unwinding to a nice read, listening to some soulful music, or trying out a new game.
