Am I the only one shaking my head that they kept comparing the M3 chips against M1 chips skipping M2?

Just like the last product release spent more time on huffing their own farts (the Apple Watch is the first of its kind carbon negative product), there is no real innovation or something to garner interest for me here.

Base 14" M3 MBP comes with 8 GB RAM at $1599 USD. That's pretty stingy.

Here in EU, the price I get in the local Apple Store is 2029€ = $2153.

Is that with or without VAT? The US always gives prices without VAT, since different states have different rates.

What's with the 36 GB option? The other memory configs (16 GB, 64 GB) are still clean powers of two. Size suggests that they're using ECC-capable memory but using the extra width intended to support ECC for data... but why would this only apply to a single size? Part availability? EDIT: Digging this a bit, it's not (one or more) 72-bit wide busses with 2^32 words as I'd expect as a gray-beard, it's (probably) six 32-…

They've been doing more multiples of 6/12 lately, I supposed it's related to the available chip sizes for the LPDDR5X.

M2 and M3 go up to 24GB

M3 Pro is available in 18GB and 36GB

M3 Max is available in 36GB, 48GB, 64GB, 96GB, and 128GB

There’s also a 18GB M3 Pro config of the MacBook Pro. Very unusual.

I don't understand why they don't update the entire lineup whenever a new chip comes out, especially if really only swapping the chip in the macbook pro and imac here. On a separate note does anyone have any insight on how unified memory compares to vram in the context of machine learning performance? Considering an H100 with 80GB costs like $30k a maxed out macbook pro with 128gb unified memory for $5k is interestin…

They just updated their macbook air and mac studios and mac pros like 6 months ago? If they updated right now, the previous owners would feel utterly screwed over.

Right but why did they just update them then? Why not do it earlier or wait for the M3?

Earlier quoted context omitted.

And yet _still_ 8GB of RAM as the baseline. It's probably as profitable as it is evil / misleading.

Calling it evil is a bit of a stretch.

I'll admit "evil" is a stretch but I was thinking in terms of the amount of e-waste this causes due to insufficient RAM hurting the longevity of a $~2k+ computer

> Additionally, support for up to 128GB of memory unlocks workflows previously not possible on a laptop, such as AI developers working with even larger transformer models with billions of parameters. The presentation explicitly highlighted this very randomly, without showing how AI development actually works. I know Apple has put more effort into Apple Silicon support for PyTorch but is it there yet?

I don't think it is? But I would love to be wrong. Cheap mobile Nvidia cards outperform regular M2 chips on small learning tasks.

M3 Max might be a contender, but Metal is far from CUDA yet? A laptop M3 Max looks like it can compete with a Nvidia 3070.

It's an unfair comparison as Nvidia is a huge desktop heat/energy hog and Apple M chips are really efficient. Let's see how desktop M3 chips fare.

The M2 Ultra tops out at 800GB/s unified memory bandwidth. A 4090, on the other hand, has 1,008 GB/s. On the PC side, dual-channel DDR4-6400 offers a bandwidth of 102 GB/s.

You will need to convince your politicians to lower import duties and taxes. And that $1599 USD is without taxes. So not the whole US has this price. It was always worth for me to travel to Oregon to have zero tax.

I think you mean, convince politicians to allow for the ridiculous tax-excluded display pricing that’s prolific in the US.
