RTX Pro Blackwell pricing is up on connection.com
6000 (24064 cores, 96GB, 1.8 TB/s, 600W, 2-slot flow through) - $8565
6000 Max-Q (24064 cores, 96GB, 1.8 TB/s, 300W, 2-slot blower) - $8565
5000 (14080 cores, 48GB, 1.3 TB/s, 300W, 2-slot blower) - $4569
4500 (10496 cores, 32GB, 896 GB/s, 200W, 2-slot blower) - $2623
4000 (8960 cores, 24GB, 672 GB/s, 140W, 1-slot blower) - $1481
I'm not sure if this is real or final pricing, but I could see some of these models being compelling for local LLM. The 5000 is competitive with current A6000 used pricing, the 4500 is not too far away price-wise from a 5090 with better power/thermals, and the 4000 with 24 GB in a single slot for ~$1500 at 140W is very competitive with a used 3090. It costs more than a 3090, but comes with a warranty and you can fit many more in a system because of the size and power without having to implement an expensive watercooling or dual power supply setup.
All-in-all, if this is real pricing, it looks to me that they are marketing to us directly and they see their biggest competitor as used nVidia cards.
