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…

In addition to the reduced memory bandwidth, the M3 pro also loses 2 performance cores for only 2 more efficiency cores. M2 pro: 8 performance cores + 4 efficiency cores. M3 pro: 6 performance cores + 6 efficiency cores. Not a great trade... I'm not sure the M3 pro can be considered an upgrade

There were comparisons to the M1 and M2 in the presentation, and indeed the linked website.

The M3 chips are 30% faster than the M2 chips for efficiency cores and 15% faster for performance cores. The overall performance is still impressive and there is no alternative to M*s when compared with performance per watt. But others have caught up, for example https://www.amd.com/en/products/apu/amd-ryzen-9-7940hs is very good.

I note that if those performance numbers are correct it'll still be a lot slower than Intel's Core i9-13980HX laptop CPU. The M2 Max was between 50% and 80% of the speed of the 13980HX on most benchmarks. A 15%-30% uplift will get it closer to the Intel part but still not reach it.

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

I'm personally always near a wall socket. My laptop is mostly a desktop. When I'm out and need to use the battery, it's only for a few hours. Do people really need >8h battery life?

At work, I'm in meetings much of the time, and I was lucky to get 4 hours of my my old MBP, if I didn't charge it over lunch, it wouldn't last the day. (there are chargers in meeting rooms, but only a few, so can't always count on getting one).

At home, I work in a few different seats (one of them is a desk with a big monitor, but for emails/reading, I prefer to sit elsewhere, including on the back deck in nice weather), all but one does have an outlet, but it sure is nice to be able to get up and move around without constantly plugging/unplugging the laptop. Magsafe does make that easier though, only takes a second to plug in and no big deal if you stand up without unplugging, it doesn't pull the laptop out of your hands or the charger out of the wall.

It was pretty hard to saturate the memory bandwidth on the M2 on the CPU side (not sure about the GPU).

The GPU can saturate it for sure.

Llama.cpp is a pretty extreme cpu ram bus saturator, but I dunno how close it is (and its kind of irrelevant because why wouldn't you use a Metal backend).

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.

Intel straggler here. And I'll remain one until Linux runs flawlessly on the newer generation. I have an older Thinkpad as my main workhorse and a now quite old Macbook air for on the road, it's battery has been shot for a long time but it still works quite good when plugged in and I'm too much of a miser to have it replaced. But if there is a way to run a full Linux distro on the newer hardware then I'll probably bu…

Check out asahilinux.org - I have archlinux arm running as my main OS on Air M1 for a year now.

my intel died last week. had to get an m2 pro and THIS drops today. kinda salty that my intel couldn' have held out till the M3 was available

I bought a top spec Intel mac a month before the M1 came out. Just sold that computer for 1/3 it's original price :\

"the most advanced chips for a personal computer", says Apple. This is not an objective statement.

Well, if you consider the entire package rather than CPU alone, I can see it. Still a misleading claim, but if stretch the definitions of “advanced” and “chip” you can do it.
