Nvidia has yet to officially reveal Blackwell-based graphics boards for professional visualization (ProViz) applications, but such cards are already undergoing testing in the wild by interested parties in Geekbench. An OpenCL benchmark result of Nvidia's upcoming RTX Pro 6000 Blackwell Workstation Edition graphics card has emerged, confirming rumored specifications of the GPU and memory while raising questions about performance.
Nvidia's RTX Pro 6000 Blackwell Workstation Edition add-in-board is based on the GB202 graphics processing unit (GPU) with 24,064 CUDA cores (188 streaming multiprocessors, 128 CUDA cores) allegedly operating at up to 2,617 MHz and carries 96 GB of memory with ECC, according to the Geekbench listing. By contrast, Nvidia's GeForce RTX 5090 — the best graphics card for gaming money can buy these days — features the GB202 GPU with 21,760 CUDA cores operating at up to 2,410 MHz and carries 32 GB of GDDR7 memory.
At first glance, the new RTX Pro 6000 Blackwell Workstation Edition graphics board should easily beat its gaming counterpart, but this is not the case as the unit scores 368,219 points in GB6 6.4.0 OpenCL benchmark, whereas the GeForce RTX 5090 can score around 376,858 in the same benchmark. A 2.3% performance difference is hardly a big deal, but given significant hardware differences between the boards, it is natural to expect the new ProViz card to beat the gaming board.
However, there are a couple of caveats. First up, we are dealing with a pre-release product with pre-release drivers, so the performance of the RTX Pro 6000 Blackwell Workstation Edition can improve when it is launched with final drivers. Secondly, the TGP of the RTX Pro 6000 Blackwell WE can be capped, and therefore its compute performance is lower than that of the GeForce RTX 5090, which can go all the way to 575W. Thirdly, the current driver limits memory visible to OpenCL applications to 24 GB (well, 23.8 GB, according to the detailed GB6 results) even though the unit carries 96 GB onboard. This proves that the driver is not final.
Also, it should be noted that based on a previous report, this the RTX Pro 6000 Blackwell is not Nvidia's flagship ProViz offering, as the range-topping model is expected to be called the RTX Pro 6000 X Blackwell.
