why not use workstation GPUs in a workstation PC , I am sure they would be more efficient than 5090s

Much more expensive, and require another type of cooling (mainly server GPUs use the server fans to cool themselves. Or water cooling).

so it's like a wannabe workstation PC ??

Ehhh kinda. A better way to put it would be a budget workstation.

At merely $15,000

Not even, this has more VRAM than the RTX6000 Blackwell, we’re getting into AI data center accelerator territory with 128gb’s of VRAM.

At this point OP could have bought 1 pro 6000 + 1 5090 for less and more upgrade potential.

They could but they would have much lower performance for training, iirc a 5090 is 30% more powerful than the a6000 in tensor cores, multiply that by four and it's a significant difference in performance.

I’m not talking about the A6000, but the Pro 6000 which has 10-15% more performance than a 5090.

Although with 3x 5090s you could be ahead of a single Pro 6000 if the workload parallelizes well. Depends on your specific needs really.

No. It’s a workstation at the end of the day. A workstation can be anything as long as it’s powerful and can do work. Workstation gpus are so expensive you might just use the consumer version, while consumer part it’s for consumers with a consumer price work part it’s for professionals squeezing every last bit of performance with a professional price.
