It's more throughput, but way less value and there's still no NVLink on the 6000. Something like ~4x the price, ~20% more performance, 3x the VRAM.

There's two models that go by 6000, the RTX Pro 6000 (Blackwell) is the one that's currently relevant.

the RTX Pro 6000 (Blackwell) does not have NVlink? if so, what the fuck Mr.leather jacket.

L40/L40S didn't have it either, which was announced late and felt like a gut-punch for the rare actual non-AI use-case at the time.

A40 nvlink was limited though, one-to-one (bridge), never saw it daisy-chained or nvswitched (might have just not seen them myself, they may have existed).

Of course it doesn't; artificial segmentation because they really want you to buy their even more expensive datacenter GPUs for AI training.
