Also note how the M1 Ultra is pushing 2/3 of the FPS of the 3090 despite 1/3 of the power budget and the game itself being poorly optimized for the M-series architecture.
And here[1] you have it smoking an Intel i9 12900K + RTX 3900. The difference doesn't look too impressive until you realize the power envelope for that build is 700-800W.
Also, the GTX 1660 (technically an RTX 2000 series, but whatever) is about 26% less efficient than an 3090[2].
> Being more efficient while being dramatically slower
That's my whole point and what you're refusing to see. The M1 is not dramatically slower than an i9 or 3090 despite having dramatically lower power use.
The proof for this will really start to come once Qualcomm and Mediatek have gotten a handle on their PC ARM chips and Valve decides they're good enough for a Steam Deck 2 or 3. You'll get to see 2-3x the battery life along a modest performance increase.
