Oh, like RTX Voice - which 'requires' a 20-series GPU as a minimum requirement. Of course after editing the installer it works just fine on pretty much any GPU with cuda cores.
I’m 100% sure RTX Voice could run happily on a cpu. Might be a fun target for one of the groups working on CPU back ends. It’s a really good NR though; I’ll give it that.
https://krisp.ai/ is basically that, but I've found RTX voice running on the GPU (1660ti) doesn't slow down my laptop while Krisp does a bit.
Did anyone ever really try to pitch that RTX Voice actually needed 20 series hardware to work as opposed to being something Nvidia were gating to try to sell more cards? I thought it was pretty transparent myself but maybe I just assumed.
Marketing needs features to sell the higher end products on. Its easier to bullshit it and artificially limit than to come up with things that physically can only work on the high end sku.
