All Apple has to do is to enable workstation-level features in its drivers and they'd beat 3090 handily. Even Titan RTX demolishes 3090 with workstation drivers in software that uses those features. As for raw performance, 3090 is far ahead.
Where do you see any gimping? It's known that NVidia gimps its consumer range by shipping drivers that are slow in some tasks despite the same hardware being able to be much faster. My comment was about Apple getting an easy win just by not doing that in pro tasks that matter, in other words beating 3090 in some apps is fairly easy due to NVidia's politics.
Yes Nvidia gimps because they have other products that are not gimped. But Apple doesn't. The M1 Ultra is the best of the best they have to offer.
I'm not saying Apple gimps their hardware. I'm asking because you are saying Apple gimps their hardware by not releasing "workstation drivers". Thus I ask you why would apple Gimp their hardware.
You were implicitly assuming that. How about: "Apple can just implement those premium features NVidia is gimping", i.e. implying Apple might not have those capabilities in their drivers yet, not intentionally gimping them.
If this transition is like the others the performance of Apple software and the operating system are going to increase with every new release for the next couple of years as they optimize it.
