Don't know what the prior extreme apple is alluding to here. But, apple marketing is what it is.

Interesting that they’re releasing M3 Ultra after the M4 Macs have already shipped.

I wonder if the plan is to only release Ultras for odd number generations.

Is there a single Apple SoC where they’ve provided removable ram? Not that I can recall.

Is there even an existing replaceable memory standard that would meet the current needs of Apple's "Unified Memory" architecture? I'm not an expert but I'd suspect probably not. The bus probably looks a lot more like VRAM on GPUs, and I've never seen a GPU with replaceable RAM.

People who know more than me: they’re talking a lot about RAM and not much about GPU.

Do you expect this will be able to handle AI workloads well?

All I’ve heard for the past two years is how important a beefy GPU is. Curious if that holds true here too.

Call me a unit fundamentalist but calling 512Gb "over half a terabyte memory" irks me to no end.

It's over half a _tera_byte; exactly half of _tebi_byte if you wanna be a fundamentalist.

Ultra disappointing, they waited 2 years just to push out a single gen bump, even my last year's iPad Pro runs M4.

For AI workflows that's quite a lot cheaper than the alternative in GPUs.

Unclear what devices this will be in outside of the mac studio. Also most of the comparisons were with M1 and M2 chips, not M4.

Is anyone other than a vanishingly small number of hard core hobbiests going to upgrade from an M4 to an M4 Ultra?

Now make a data center version.
