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.
