I thought the memory was one of the more interesting bits here. My 2-year-old Intel MBP has 64 GB, and 8 GB of additional memory on the GPU. True, on the M1 Max you don't have to copy back and forth between CPU and GPU thanks to integrated memory, but the new MBP still has less total memory than my 2-year-old Intel MBP. And it seems they just barely managed to get to 64 GiB. The whole processor chip is surrounded by…

Just some genuine honest curiosity here; how many workloads actually require 64gb of ram? For instance, I'm an amateur in the music production scene, and I know that sampling heavy work flows benefit from being able to load more audio clips fully into RAM rather than streaming them from disk. But 64g seems a tad overkill even for that. I guess for me I would prefer an emphasis on speed/bandwidth rather than size, but…

As a data scientist, I sometimes find myself going over 64 GB. Of course it all depends on how large data I'm working on. 128 GB RAM helps even with data of "just" 10-15 GB, since I can write quick exploratory transformation pipelines without having to think about keeping the number of copies down.

I could of course chop up the workload earlier, or use samples more often. Still, while not strictly necessary, I regularly find I get stuff done quicker and with less effort thanks to it.

Metal is Metal. Once you support Metal for iOS games they also work under MacOS when running on Apple's chips. You can support traditional MacOS application chrome with little additional effort.

Desktop games and mobile games are not the same. On mobile pretty much every heavy game uses either UE or Unity. High end PC games use custom engines that are heavily tuned for x86 and use different APIs. Metal port would be expensive and not worth it.

>High end PC games use custom engines

High end PC games tend to license somebody else's engine.

The most popular of those gaming engines already support Metal.

"Apple’s Commitment to the Environment" > Today, Apple is carbon neutral for global corporate operations, and by 2030, plans to have net-zero climate impact across the entire business, which includes manufacturing supply chains and all product life cycles. This also means that every chip Apple creates, from design to manufacturing, will be 100 percent carbon neutral. But what they won't do is put the chip in an expan…

What the hell does this have to do with the chips?

Single connector, the 3.1 spec goes up to 5A at 48V. You need new cables with support for the higher voltages, but your "multiple plugs for more power" laptop is exactly the sort of device it's designed for. It was announced earlier this year, so not in wide use yet. PDF warning: https://usb.org/sites/default/files/2021-05/USB%20PG%20USB%2...

I’ve not seen any manufacturer even announce they were going to make a supported cable yet, let alone seen one that does. I might’ve missed it though. This will only make the hell of USB-C cabling worse imho.

Currently I think there aren't any, and the MBP will only get its full 140W capacity using the magsafe cable.

Does the M1 Pro/Max support running/building x86 Docker images using x86 hardware emulation? As as developer, this is the feature I've missed the most after having used my M1 MacBook Air for about a year.

docker buildx should be able to handle it, no?

What makes you think that?

On a desktop Hackintosh, I started with 32GB that would die with out of memory errors when I was processing 16bit RAW images at full resolution. Because it was Hackintosh, I was able to upgrade to 64GB so the processing could complete. That was the only thing running.

What image dimensions? What app? I find this extremely suspect, but it’s plausible if you’ve way undersold what you’re doing. 24Mpixel 16bit RAW image would have no problem generally on an 4gb machine if it’s truly the only app running and the app isn’t shit. ;)

I shoot timelapse using Canon 5D RAW images, I don't know the exact dimensions off the top of my head but greater than 5000px wide. I then grade them using various programs, ultimately using After Effects to render out full frame ProRes 4444. After Effects was running out of memory. It would crash and fail to render my file. It would display an error message that told me specifically it was out of memory. I increased the memory available to the system. The error goes away.

But I love the fact that you have this cute little theory to doubt my actual experience to infer that I would make this up.

The AMD chips in the PS5 and new XBox reach 448GB/s and 326GB/s bandwith respectively with their unified memory.

Not entirely true. Xbox Series X has two different memory bandwidths. The first 10GB has 560GB/s and the last 6GB has only 336GB/s.

Yeah it's an interesting setup. I believe the 560 is prioritized for graphics processing and 336 for more general tasks.

It’s interesting that the M1 Max is similar in GPU performance to RTX 3080. A sub $1000 Mac Mini would end up being the best gaming PC you could buy, at less than half the price of an equivalent windows machine.

Similar to an RTX 3080 Mobile , which is IIRC equivalent to somewhere around a RTX 3060 Desktop.

Even that is doubtful until we see 3rd party benchmarks.

There is 0% chance that game dev supports mac, it's a dead platform for gaming. The downvote police is there, am I missing something? are they any modern game on mac? https://applesilicongames.com/

EVE Online now supports M1. But regardless, now that MacBooks are capable gaming machines (definitely not the case in the past), and a core demographic of Mac users overlap with the gaming demographics (20-40 yo), I really think it’s just a matter of time now.

I would argue that Macs with PC-shared Intel CPU's and AMD GPU's should have been much EASIER to support than the new, completely-different architecture, and that hasn't really happened.
