You can downvote me all you want, it does not matter. You can call all ARM chips "laptop" grade all you want. But this misrepresents how this arch is used in servers and desktop "PCs" right now. And thats the only point I want to make. ARM arch chips are not laptop only. Can they match the power of this new I9? No. But that wasn't my point.

You can get x86 chips designed for laptops in desktop form factors too.

It's not about Arm. All of Apple's M chips so far have been primarily designed for mobile use, and that strongly affects how the power usage scales. It makes a basic comparison of watts not very useful.

There, you said it again. This is wrong - you hear Apple M chip and you think "laptop" primarily, but that is no longer true. Just as it would be to say ARM is primarily for smartphones. Now I don't want to talk about sales numbers, but the M chips in the Apple Studio and Mac Pro (and those used by other manufacturers in servers) are a different category than "laptop". For a quick shallow impression see: https://nanoreview.net/en/cpu-compare/intel-core-i9-14900k-v...

(nevermind it's the i9-14900K)

Again, the I9 is more powerful, but that doesn't make all of ARM or M a "laptop".

The M2 ultra is basically two M2 Maxs stuck together. It's the same chip that's in laptops, and was designed around a laptop power budget.

In what way is it in a different category?

Designing for different power targets has a significant effect on power and performance metrics. When a chip is designed to be able to take tons of watts, that hurts its efficiency even when you're currently running at a low wattage. So comparing chips with different wattage philosophies gets tricky.
