Bingo.It's not going to solve the heat issues from a real ultra chip in any meaningful way. A couple of percent? Sure. But not the massive improvement needed, which would be quite a bit above 50%. And the thinner the laptop would be, the fewer watts the chip can use.
Of course, they could just rebrand a non-ultra chip.
Also there's no evidence about the thinness of this device. It's all speculative.
We got weird P cores with M5, they could give us a weird mobile Ultra variant of that in an updated chassis, 16"+ only, designed entirely around cooling like e.g. the Studio and the iMac Pro were.
It's going to cost like $6000 starting if that happens, and it will sell.
The iPhone Pro got larger and thicker, I don't know why everyone thinks the laptop cannot, consumers have shown they will purchase bricks that are slightly faster or more capable.
And once again, I repeat, the touch screen may not be where everyone thinks it is. We'll see.
