OK, if we’re talking about infrastructure rather than specific equipment, then yes, I would broadly agree that the datacentre infrastructure itself can be repurposed.
Unfortunately, by that point the whole data centre will already have been sold off for parts because its never going to recoup its initial investment in the first place, and throwing even more money into swapping out those GPUs for CPUs is going to be a complete no go.
If anyone actually spent money on science anymore, I bet this would be great for, like, protein folding, that sort of thing.
Terrible for running websites though.
GPUs are only good for workloads that multi-thread really, really well. That’s why we don’t just use them as CPUs.
The idea that today’s GPU will be tomorrow’s CPU makes no sense. We’ve had GPUs for ages. If they were capable of being used in place of CPUs we’d already be doing it. Why aren’t yesterday’s GPUs today’s CPUs?
We’re talking about repurposing the GPUs, not the AI.
