No mention of processor speeds, just like iOS devices. This is the new normal now for Macs.

If you use it, and it is faster, do you care what the numbers are?

if you hear "3x times faster" would you like to know the baseline or just blindly trust that the metric is correct? if you don't care, they would never show the "3x times faster" metric at all, but they do for a reason

Earlier quoted context omitted.

Yes, they have an Intel emulator (Rosetta I think they called it) and are pushing developers to produce "universal apps".

"Universal apps" that only run on OSX and Apple's mobile OS I presume?

Universal apps run on both Apple Silicon (ARM) processors and Intel processor-based Macs.

I'm very curious to see some real benchmarks. I have no doubt that they've achieved state of the art efficiency using 5nm, but I have a harder time believing that they can outperform the highest end of AMD and Intel's mobile offerings by so much (especially without active cooling). Their completely unit-less graph axes are really something...

Someone will probably Geekbench it by next week.

Did I understand correctly that MacBook Pro and Air will share the same M1 CPU? Previous models had a massive delta in CPU performance based on using low power (Air, no fan) or medium power (Pro, with dual fans) Intel chips

Same CPU line, but doesn't mean they will have the same specs. Pro will definitely have its cores run faster/hotter.

Completely unconfirmed speculation incoming:

There's a solid chance that the logic board is exactly the same on all of the Macs announced today and the only difference is the cooling solution. If you play around with the Apple Store configurator, the specs are all suspiciously similar between every new Mac.

Apple mentions TensorFlow explicitly in the ongoing presentation due to the new 16-core "Neural Engine" embedded in the M1 chip. Now that's an angle I did not expect on this release. Sounds exciting! Edit: just to clarify, the Neural Engine itself is not really "new": > The A11 also includes dedicated neural network hardware that Apple calls a "Neural Engine". This neural network hardware can perform up to 600 billio…

I can't see how something that tiny can compete in any meaningful way with a giant nVidia type card for training. I'd imagine it's more for running models that have been trained already, like all the stuff they mentioned with Final Cut.

Yeah I would imagine it's intended for similar use-cases as they use for iOS - for instance image/voice/video processing using ML models, and maybe for playing around with training, but it's not going to compete with a discreet GPU for heavy-duty training tasks

Max 16GB of RAM on these new machines is really not that great to be honest. The mini supported up to 64GB before.

Holy cow, that's true. New 2020 Mini with a 16GB RAM, seriously?

Especially head scratching when you consider that a lot of folks still have 2012 Mac minis with 16GB of RAM.

I think 16GB is the bare minimum for a professional machine. Apple clears the bar here, but doesn't exceed it.

Maybe next year's machines? As a first product, I think it's good enough. And the performance gains elsewhere--if what Apple says is true--are actually pretty radically impressive.

For an 18-hour battery life computer (Macbook Air) that now doesn't even have a fan, it's for a complete different market segment from where nvidia cards dwell.

Really, 16GB max? I find it very strange how Apple went from targeting professionals, seeing the strategy work from the ground up for many years, but now somehow want to pivot to hobbyists/others instead of professionals. Could someone try to help me figure out the reasoning behind Apple changing the target customer?

This is their 13" model. Their 15" model is targeted for professionals.

There is no 15" model anymore and the 16" model has not been announced with an M1 yet.
