It looks like these models won't be as useful for LLM inference which are heavily memory bandwidth constrained. The Macbook Pro page shows M3 at 100GB/s,150GB/s, and 300GB/s vs M2 at 200GB/s and 400GB/s. 400GB/s is available for M3 if you opt for the high gpu config, but interesting to see it go down across all of these models.

So they remove MacBook 13 inch and replace with MacBook 14 inch as base. Many people will see the $500 off. Good selling strategy. Btw, I didn't see the comparison with M2 chip. Could anyone give me the reference for that? Thank you.

They had multiple slides for M1/M2/M3 in the video. M3 is around 15% faster than M2 in most benchmark (according to Apple).

Thank you.

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-…

It has nothing to do with ECC. They are using LPDDR5X memory, and if you follow Android phones these number shouldn't be surprising.

Can we use more than one external display yet?

Seemingly no. So far it looks like (someone please correct me if I’m wrong): - M3, 1 external display - M3 Pro, 2 external displays - M3 Max, 4 external displays This has to be a product differentiation decision at this point, right? Is there any serious technical limitation against more displays in the base chip, that Apple has not been able to solve in three generations?

Mac Mini with the M2 Pro can drive 3 monitors, Macbook Pro with the M2 Pro only 2.

One thing that left me a bit confused was the comparison against Intel Macs. Although I am still using an Intel 16-inch MacBook, I really wanted to see how the M3 fared against the M2, not Intel and M1. I think it's no surprise the M3 exceeds the Intel Core i7-9750H in basically all of Apple's own benchmarking. My real question, which will probably be answered next week, is how it compares to the generation right bef…

I still know a number of my colleagues who haven't jumped onto the Apple Silicon machines despite our 2019 Intel machines being out of warranty (and thus eligible for replacement) for two years now

I imagine the amount of people upgrading from an M2 Mac will be close to 0, while there's a lot of Intel stragglers out there.

It's shiny but I think I'll stick to my upgradable RAM and two m2 slots + a RTX 3070ti and i7-12700H for a fraction of the price. Something at Apple broke when they switched to their own silicon outside iPad and iPhone. They turned around the slow march toward parity on price:performance/RAM/storage and went screaming in the other direction. I really wanted to switch to mac when I was shopping for a new system earlie…

I tried to find a laptop with the specification you just mentioned that could last 20 hours on battery. Didn’t.

A few things I noticed, as I'm seeing the variety of SKUs becoming more complex.

- Note that memory bandwidth is down. M2 Pro had 200GB/s, M3 Pro only has 150GB/s. M3 Max only has 400GB/s on the higher binned part.

- Just like the low-spec M3 14" has one fewer Thunderbolt port, it also doesn't officially support Thunderbolt 4 (like M1/M2 before it)

- The M3 Pro loses the option for an 8TB SSD. Likely because it was a low volume part for that spec.

- The M3 Pro actually has more E-cores than the Max (6 vs 4). Interesting to see them take this away on a higher-specced part; seems like Intel wouldn't do this
