Apple have caveated the comparison by specifying "PC laptops" and according to NVidia's own site [1], and clicking through to see the actual specs [2], there aren't any currently available that out-spec a 16GB 3080 Ti.

I'll admit I haven't gone spelunking down the specialist laptop manuafacturer sites, but on the surface it seems to be not an unrealistic claim.

Sure, but the claim is:

> creators can work on scenes so large that PC laptops can’t even run them

You can't open a 40GB scene entirely in GPU RAM on any single-GPU system, laptop or otherwise, because there aren't any 40GB+ GPUs.

But you can open a 40GB Octane demo scene with out-of-core loading enabled on a Windows laptop with 64GB of RAM. Hell, Otoy has a demo from 2018 of a Windows system loading and editing that "worst-case" 40GB scene entirely out-of-core at 60fps.[1]

So the suggestion is that the M2 is doing it without enabling out-of-core loading because all system RAM is in-core. Which is cool, and something Otoy's CEO was boasting on the M1 MBP's release day two years ago.[2]

So why bother going through the motions of benchmarking anything like this against 2+-year-old systems, just to make a claim the M1 also made, just less precisely?
