> sometimes performance per watt is more important especially when you're mobile or trying to be conservative w/ electricity.

There is an obvious implicit context when you're comparing performance to an RTX 3090, and it is not mobility or your electric bill.

There may be only one implicit context for you, which is why I said "better" is subjective.

Personally the M1 Ultra would be better imo as a desktop GPU than RTX 3090 in certain contexts. Putting it in a van, traveling with it, etc.

I'll probably wait until the next go around of them, but I'm loving nearing desktop performance w/ reduced loads.

The RTX series has lower power variants. When you compare against the 3090 you are establishing a context with power consumption as a low priority.

Considering the 3090 had over double the performance, the lower power parts may well be both faster and more power efficient. You'd have to do the comparison to know, if that's what you care more about.

> 3090 had over double the performance

The FPS was closer than double. The flawed benchmark the 3090 had double.

I'm not sure how the lower power RTX variants compare, maybe that's a closer comparison, has there been a review against those?
