I'm still using a 2015 macbook for my personal daily driver. I have to plug it in regularly, but otherwise it works just fine for everything except video editing.

I thought the same, but ended up upgrading to an M1 Air due to a hardware failure. Sure it feels 100x faster. But more than that it’s DEAD SILENT (no fan in the machine!) and completely cool. The temperature/noise, if I had experienced it myself first, would have probably gotten me to upgrade. I use a 2019 Intel MBP at work. It’s much faster than my old 2015 too, but with the additional heat and noise I didn’t really…

I got an M2 Pro Mini a couple of weeks ago to replace my 2018 i7 MBP and while it is obviously snappier and you feel it's more powerful without running benchmarks the main difference is that: it is silent. I only got it warm to the touch rendering video with Da Vinci, when CPU temp usage quickly went to 75ºC.

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 also appears they've dropped the memory bandwidth from 200GB/s on the M1/M2 Pro to 150MB/s on the M3 Pro, and you have to upgrade to the tippy top M3 Max chip to get the full 400MB/s bandwidth experienced on the M1/M2 Max chips.

(Just pointing out that all these numbers are in GB/s)

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

One and a half 12-chip?

Or a 12 plus a binned 8?

Intel straggler here. My laptop just completed 5 years. It says battery needs replacing which I’ve been putting off for a year. The thing is I have 32G which is quite good IMO so I’ll probably use it for two years at least.

You're just hurting yourself. Even the M1 Pro is like 3x faster than that Intel laptop. Plus so many tiny things like sleep/wake, power management, heat.. I really can't stress enough what a tectonic change the M1 was over Intel.

But how will I ever survive without my touchbar?

At a ~recent work place the entire floor of developers had (Intel) MacBook Pros with dual 24" monitors. Some of them were trying out Apple Silicon replacements, though I'm not aware of what they did monitor wise. Probably used the excuse to buy a single large ultrawide each instead, though I don't actually know. ;)

Which workplaces are these that buy low-end laptops for their employees but shell out for dual monitor workstations?

> low-end laptops

you're saying they're low-end because Intel? if you've got your macbook connected to two monitors, you're not very concerned about battery performance.

So isn't Intel silicon competitive speedwise? I thought the M[0-4]s were OK but sort of hypey as to being better in all regards.

This is cool, where can I buy the chips and read their datasheets?

It's even better, you can buy the whole machine, with a great monitor, connectors, a keyboard, and so on!

I want to build a cluster and run it in a data center.

For years now, Apple's biggest competitor is Apple from five years ago. One of their biggest threats is that sales flatline because people are still using their perfectly good laptops and phones from several years ago. And that's a hard problem to deal with when you advertise your products as high-end goods that will last a long time.

This shouldn't be a problem, and the answer is to refresh devices less frequently.

The whole company is sized to a specific revenue stream, and this revenue stream requires a specific sales volume. Apple could get off Mr. Bones' wild ride, but this would require remaking how the whole company works:

- less frequent laptop releases mean lower sales (do you want this 2020 Mac or this 2023 Dell?)

- lower sales mean lower revenue, lower revenue means lower costs

- so now Apple has to spend less on R&D and at the same time convince its board of directors that lower sales don't mean Apple is failing

And I want a free pony, but nobody obliges!

It’s kind of strange their benchmark for “Machine Learning Programmers” is “Simulation of Dynamical Systems in MATLAB.” Seems like they could have capitalized better by using a generative ai inference benchmark.

iPhone 15 Pro NPU can do 35 TOPS. M3 can only do 18 TOPS. That's why they didn't focus on ML in the video.

Its big question mark with 35 TOPS, because its extremly limited and hard to achive.
