The M1 MacBook Air... is a fanless, ultra lightweight laptop with no dedicated GPU and 20-hour battery life.…. I’d say that’s pretty impressive when we are yet to see a Mac Pro on  Silicon.

I've just been wondering if the Pro haven't used Apple silicon because it doesn't scale up to it. Their chips are insanely impressive, but can that 20W thing scale up to 120W and actually have 5-6x the power? And if it can, why haven't they done it?

There’s already been benchmark leaks with 96GB of RAM, there’s a Covid-situation going on in China currently and likely the launch has been postponed to the end of the financial year.

Perhaps? The M1 Ultra is basically two M1 chips glued together with a bunch of extra GPU cores.

There isn't an M2 Ultra right now, but it's probably only a matter of time until that gets released.

I think M1 Max is basically 2 M1 chips and M1 Ultra is basically 4 M1 chips

The M1 Max is an M1 Pro with extra Gpu cores

The M1 Ultra is 2 M1 Max’s

The Mac Pro is expected to have a chip made of 2 M1 Ultras

Isn't that going to limit the single core to being not much higher than the original M1? Maybe with more power and cooling they can crank it up a bit, but it seems like that's the limit.

Not really sure what you're saying. Single core is pretty consistent between M1 to M1 Ultra

Yeah, talking about the pro line. If they're stuck at M1 single core speeds at desktop level it'll suck for certain applications.

Err the single core performance of the M1 chips is very high, I think when they were released they were the most powerful single cores available.

Hm, I don't see it that was at all.

If we look at how Intel chips scale, we see that single core performance actually decreases on the largest chips. That's why historically the Xeon Mac Pro would actually have a lower single core performance than the similar generation i5 or i7.

Of course the Xeon would more than make up for it by having tons of cores, more PCIe lanes, support for ECC RAM, etc.

I think it would be fantastic if the M1 Supermega or whatever they end up calling the Mac Pro chip matches the M1 single core performance.

Mac airs are shit.

Half my office got those from IT.

I got a 4lb Asus work station with an A5000... ;p

(Basically I use it to run freaking CAD software but only to review engineering, hell for fun I run blender renders I set up at home and send over to render in the background while I work.
