Did they really just claim 30-series tier performance on the max GPU? If that's true that would be insane!

Equivalent to "the notebook with the fastest GPU we could find at half the power" is how I remember it... I'm just not entirely certain what GPU performance does for me...? I don't work with video, there aren't any games, and I'm not playing them, anyway. Does iTerm2 scrolling get better? I used to be quite happy with the GeForce 7xx(?) and tensorflow, and this seems like it would have quite a bit of power for ML. Unfortunately, the software just isn't there (yet?).

the comparison was only on laptops, but still impressive if they did that with 70% (?) less power

  Well, no - they immediately followed the discrete laptop graphic comparison with a desktop graphic comparison, highlighting how much more power they draw for "the same" performance.

    > Well, no - they immediately followed the discrete laptop graphic comparison with a desktop graphic comparison pretty sure the comparison was with "the most powerful PC laptop we could find", which makes sense because they then talked about how much it was throttled when running only on battery while the new M1 is not.

    That wasn't for desktop graphics, it was for a top-end laptop graphics SKU (I think RTX 3080 Mobile on a ~135W-150W TDP configuration?). Otherwise the graph would extend all the way to 360W for a RTX 3090.

      Yup - I misheard while watching. The chart only shows a line up to about 105W, so it's not clear what they're trying to represent there. (Not that there's any question this seems to be way more efficient!)

      And I think based on these numbers that a desktop 3090 would have well over double the performance of the M1 Max. It's apples to oranges, but lets not go crazy just yet. Now, I am extremely excited to see what they will come up with for the Mac Pro with a desktop thermal budget. That might just blow everything else by any manufacturer completely out of the water.

> claim 30-series tier performance on the max GPU? If that's true that would be insane! TDP, TDP, TDP! With big enough heatsink, the performance can be proportionally high (perf = sqrt(TDP))
- KarlKemp 5y ago
  ...but they are claiming 50-70 % lower power usage, and therefore 50-70 % lower TDP as well.

GPU workloads are very parallel. By throwing more transistors at the problem while lowering clock rates you can get pretty good performance even in a constrained power budget.
