Is this a drop in replacement for clouds (which is the actual question to ask because if you are buying this you have to make new infrastructure) the answer is No. Will Microsoft and Oracle allow you to use this to rent ? Yes. Does Microsoft and Oracle need more accelerators to do internal business processes? Absolutely (Microsoft announced it would rent AI accelerators because they can’t keep up with their own internal (and maybe external) demand). So cost has to not just be per card but infrastructure build out .
Not sure when Microsoft will just have their own TPU accelerator but I wouldn’t be surprised if the announce it sometime.
