Linus reviews 6800 Mobile

TLDR: Loses to the 3080 mobile in every way... AMD also claimed that the 6000 series might perform better on just battery but that was false as well.

But the one thing the review didn't mention is the price!

If you look at laptop prices, the price of a 3070 laptop is very similar to the price of the 6800M equipped laptop! And considering it can get close to a 3080 Laptop... That's quite the good deal.

Finally got around to watching the video, and I find that your tl:dr is very misleading:

  1. The 3080 is in a bigger and thicker 17" Laptop versus the 15" for the 6800M, giving the 3080 much more cooling headroom
  2. The 3080 ran at a 20-30W higher power consumption than the 6800M, with the 6800M stuck between 105W and 110W while the 3080 fluctuated between 120W-140W. Combining this higher power limit with the bigger cooler from the bigger chassis, no small wonder the 3080 won out in those tests. It would have been catastrophic for NVidia if they didn't under those conditions.
  3. The AMD laptop did perform better when just running on battery. It didn't suddenly beat NVidia, but the performance gaps did get somewhat smaller

1) Cooling headroom doesn't matter in this case because neither GPUs were thermal throttling and had headroom to boost higher if they could

2) Considering the laptop for the 6800M has a power budget of 145 Watt and had the same thermals as the 3080M, there was nothing stopping it from boosting any higher other than it's design. If AMD is limiting it to 116 Watts peak where as Nvidia is allowing their GPUs to boost higher, then it's an inherent flaw with the 6800M design because it's supposed to be rated to go up to 145 Watts unless there's thermal issues which the video says it doesn't.

3) It got slightly smaller where as their presentations made it sound like there would be a big difference when in reality, there really wasn't. Especially when you considering how efficient TSMCs 7nm is supposed to be against Samsung's 8nm.
