I believe the 3070 uses a different die from the mobile 3070. The mobile and discrete parts have completely diverged so comparisons are meaningless. Laptop GPU performance is entirely a question of power and cooling.

In their charts, they showed it's about even (in performance, with much lower power consumption) with a laptop using a RTX 3080 (Mobile), which performs about as well as an RTX 3060-Ti / 3070 (Desktop). So that's pretty wild. More and more games getting playable on macOS too through native ports or emulation, so in theory you wouldn't need a gaming PC anymore. These numbers are for the M1 MAX though, which is a bit more expensive.

  Not sure where you’re getting that from? This [1] appears to be the machine they compared with (assuming the part number actually refers to a unique spec), which only has a 3050 Ti?

EDIT: Nevermind, they mention other laptops in the other slides, some of which do have a 3080.

      Fascinating. I have pulled the trigger on an M1 Max to replace my i9 MBP, and wasn’t hopeful for the GPU. But now I am VERY curious how well it will do at gaming using CrossOver Mac. I’d been eyeing a getting a 3080 laptop as a secondary for being able to do mobile gaming, but an M1 Max + CrossOver Mac setup might scratch that itch with only a single laptop. A fun experiment for next Tuesday.

A desktop RTX 3070 is 50-60% faster than a mobile RTX 3070. Which ofcourse is understandable.

  > Which ofcourse is understandable It really isn't. Nvidia should be using clearly differentiated model numbers to represent two completely different lines. They did this to intentionally confuse customers.

    They even did for a generation, with the 10xx series. But their partners probably weren't happy that the highest end laptop sku was a xx60, so here we are again.

    Yes the naming is very confusing but it is understandable that a desktop GPU can be faster than a laptop GPU.

They're both GA104, but the desktop version does have 15% more cores enabled and 30% higher clocks.
