Nvidia layman here: this is the same generation as the 5000 series, so why is it designated 6000? Do the PRO cards have their own generation line or is it similar to AMD and their mobile GPU versioning?
This is derived from the Quadro lineage. The 6000 model typically denominates the highest end design that shares the core architecture with the gaming models, since Fermi
Quadro 6000 (GF100), roughly same core as GTX 470
Quadro K6000 (GK110), same core as Titan Black
Quadro M6000 (GM200), same core as GTX Titan X
Quadro P6000 (GP102), same core as Titan Xp
Quadro RTX 6000 (TU102), same core as Titan RTX
RTX A6000 (GA102), same core as RTX 3090 Ti
RTX 6000 Ada Generation (AD102), same processor type as RTX 4090 but with a lot more cache and SMs enabled
RTX PRO 6000 (GB202), in the same vein as its predecessor against the RTX 5090
Quadro GP100 and GV100 rank higher than their respective generation's "Quadro 6000" and Titan models, GP100 never saw a consumer release and the GV100's "consumer grade" counterpart is the Titan V.
