NVIDIA submitted two workstation SKUs to Khronos Group, a non-profit consortium creating royalty-free interoperability standards for 3D graphics, in February. The 18th February entry shows that the cards: Quadro RTX A5000 and A4000, are unannounced and have received the OpenCL 1.2 certification.
There is a high probability that the Quadro RTX A5000 will feature the GA104 GPU while the A4000 will have GA106 GPU. One interesting thing to note is that the cards are still listed as Quadro, a brand name which NVIDIA replaced for a simpler yet confusing name, ‘RTX Axxxx’ naming system. The OpenCL conformance filing has used the Quadro RTX Axxxx branding to list the cards.
Just before officially releasing their RTX A6000 workstation GPU, NVIDIA changed to RTX Axxx naming from the initial Quadro RTX naming. However, NVIDIA still lists the card as Quadro on their official website.
The Quadro Turing series utilized full GPUs. If NVIDIA has the same rule for its Ampere workstation series, then RTX A5000 will have up to 6144 CUDA cores while the core count for A4000 will be 3840 CUDAs cores. The memory configuration is a little hard to predict, but one card from NVIDIA is equipped with 48GB RAM, which means that the A5000 might feature 32GB or 16GB GDDR6 memory, while A4000 might have 12GB.
