Really? The M1 is a bit slower than a 1650, so 4x that performance gets you solidly into 3000 series range. There might be a handful of PC laptops that can outpace the M1 Max, but none in remotely comparable a package.

There is no way a SoC is running in the same range as an NVideo 3000 series GPU. The GPU performance of my M1 Mac Mini is roughly comparable to that of my Pixel 5 and Quest 2--both of which are running the Qualcomm Adreno 650 GPU.

  If (Big if) the provided graphs on apple's M1 Pro & M1 Max article are to be believed you're getting 90% the performance of a RTX 3080 Mobile (A 3070 with a clockspeed cut) but at a quarter of the power draw. This seems to be quite a development.

    For all the other claims on GPU performance, they call out that they are comparing to the integrated graphics, and they name the GPU specifically. With this one claim, they name a computer, but not the GPU. "Compared to a computer that has a laptop 3080 in it" is not the same thing as "compared to a 3080." And they don't define "performance". Is it fill rate? Is it TFLOPs? Is it memory bandwidth? The M1 Max has 64 GPU cores. That sounds like a lot! It's not! The NVidia Laptop 3080 has 6,144 cores. That's NINETY SIX TIMES as many cores. I'm sorry, but supposedly achieving 90% of the "performance" of a GPU that has 2 orders of magnitude more cores is just not in the realm of believable. They are being intentionally evasive here.

      They very much put some numbers on performance in the keynote, you can go back and watch it. The Max: 10.4 tflops 327 gtexels/sec 164 gpixels/sec

        What I see on desktop 3080 is: 465 Gtexels/s 164.2 Gpixels/s if those numbers from Apple are real -- that's bonkers

      Wouldn't the 3080's core count you mentioned be more comparable to the 'Execution Unit' quoted on Apple's slides: 4096 EUs on the 32-core variant? https://images.anandtech.com/doci/17016/2021-10-18%2019_21_17.jpg https://images.anandtech.com/doci/17016/2021-10-18%2019_21_1...
