This is about the processors, not the laptops, so commenting on the chips instead. They look great, but they look like they're the M1 design, just more of it. Which is plenty for a laptop! But it'll be interesting to see what they'll do for their desktops. Most of the additional chip area went into more GPUs and special-purpose video codec hardware. It's "just" two more cores than the vanilla M1, and some of the effi…

You'd have to be extremely old to remember that era. Lots of stuff important to making computers work got split off into separate chips away from the CPU pretty early into mass computing, such as sound, graphics, and networking. We've also been sending a lot of compute from the CPU into the GPU as late for both graphics and ML purposes.

Lately it seems like the trend has been taking these specialized peripheral chips and moving them back into SoC packages. Apple's approach here seems to be an evolutionary step on top of say, an Intel chip with integrated graphics, rather than a revolutionary step away from the era of general purpose computing.

DDR5 isn't common yet. DDR4 is the common desktop/laptop chip. LPDDR5 is cell-phone chip, so its kinda funny to see a low-power RAM being used in a very wide fashion like this.

Don't cell phones sell more than desktops, laptops, and servers? Smartphones aren't a toy: they are the highest volume computing device. They are also innovating with things like on-chip ECC for LPDDR4+, while desktop DDR4 still doesn't have ECC thanks to Intel intentionally gimping it for market segmentation.

Well sure. But that doesn't change the fact that DDR5 doesn't exist in any real numbers.

LPDDR5 is a completely different protocol from DDR5 by the way, just like GDDR5 is completely different from DDR3 it was based on. LPDDR3 was maybe the last time the low-power series was something like DDR3 (the mainline).

Today, LPDDR5 is based on LPDDR4, which diverged significantly from DDR4.

DDR5 will have on-chip ECC standard, even unbuffered / unregistered.

I'm switching now, after waiting for the M1 16' one for more than a year now.

However, my current laptop is a 2015 MacBook, I've never had any issues with it when it comes to coding. If anyone here's switching and you don't do anything like 3D/video editing, I'm curious what's your reason?

To finally use my laptop as it's intended: without being tethered to an outlet. The battery life on these is phenomenal.

And only 10 cores so a 5950x completely wreck an M1.

What application makes full use of 5950x all cores?

Video encoding, ray tracing. Prime95 if you're trying to stress test your CPU and memory.

Apple, the company that requires the entire panel to be replaced by design when a 6 dollar display cable malfunctions, is proud to announce its latest marketing slogan for a better environment.

Just because you're not getting that panel back doesn't mean it's destroyed and wasted. I figure that these policies simplify their front-line technician jobs, getting faster turnaround times and higher success rates. Then they have a different department that sorts through all the removed/broken parts, repairing and using parts from them. No idea if this is what they actually do, but it would be the smart way to han…

Even in school we were taught the lessons to better and sustainable environmental habits: Reduce, Reuse, Recycle

In the very same order.

So, no sir. Apple isn't the environment friendly company that they claim to be. So much money, and so little accountability.

I was thinking the exact same thing! The fanless M1 Air is a dev monster in a mouse package. Couldn’t be happier with that combo.

If the M1 supported 3 displays I would’ve bought an air last year. Feels like I’ll have to pay a lot for that 3rd monitor!

This, I currently run triple 24inch monitors in portrait off my work 2019 16" laptop rather smoothly. Unfortunately the M1 couldn't run it. The new 14 and 16 max can do triple 4k.

Up to two external displays with up to 6K resolution at 60Hz at over a billion colors (M1 Pro) or Up to three external displays with up to 6K resolution and one external display with up to 4K resolution at 60Hz at over a billion colors (M1 Max)

Yes, it depends on what you're doing, but if you can watch 21 hours of video, many people will be able to do more than 24 hours of development.

Video playback is accelerated by essentially custom ASIC processing built into the CPU, so it's one of the most efficient things you can do now. Most development workloads are far more compute intensive.

I know everyone's use case is different, but most of my development workload is 65% typing code into a text editor and 35% running it. I'm not continually pegging the CPU, just intermittently, in which case the existence of low power cores help a lot. The supposed javascript acceleration in the M1 has seemed to really speed up my workloads too.
