No. These are practically useless for AI.

Their prompt processing speeds are absolutely abysmal: if you're trying to tinker from time to time, a GPU like a 5090 or renting GPUs is a much better option.

If you're just trying to prep for impending mainstream AI applications, few will be targeting this form factor: it's both too strong compared to mainstream hardware, and way too weak compared to dedicated AI-focused accelerators.

I'll admit I'm taking a less nuanced take than some would prefer, but I'm also trying to be direct: this is not ever going to be a better option than a 5090.

They are not. This is Blackwell with Tensor cores. Bandwidth is the problem here.
They're abysmal compared to anything dedicated at any reasonable batch size because of both bandwidth and compute, not sure why you're wording this like it disagrees with what I said.

I've run inference workloads on a GH200 which is an entire H100 attached to an ARM processor and the moment offloading is involved speeds tank to Mac Mini-like speeds, which is similarly mostly a toy when it comes to AI.

Again, prompt processing isn't the major problem here. It's bandwidth. 256GB/s bandwidth (maybe ~210 in real world) limits the tokens per second well before prompt processing.

Not entirely sure how your ARM statement matters here. This is unified memory.
