It's no secret that Apple's M2 series processors are a pretty minor improvement over the M1 series. Expect much bigger improvements in the M3 series which will likely be using TSMC's 3nm process (and then probably only minor improvements again for the M4 series). It seems that Apple's ridiculously impressive consistent year-on-year gains up the M1 were in large part possible because they were behind the state of the…

Yes, the year over year improvements were 90% just the tsmc node changes. But the ridiculous (and IMO amazing) performance per watt is a mix of iOS/macOS and their chip design. Those efficiency cores are unmatched, paired with the right scheduling from the OS. The M2 is underwhelming as its the same 5nm as the M1 was. But rumors say the M2 pro and max are on the 3nm node. And it took so long for the release, as 3nm w…

Not disputing this, but even Asahi Linux without GPU acceleration has pretty much whole-day battery life on an M1 Air. I'm not sure how well their kernel manages scheduling on the different cores but I suspect the vast majority of the perf/Watt is on the actual hardware.

If Hector Martin doesn't say that they fixed the memory-mapping bug in their PCIe controller[0] I think it's safe to say that we're not getting a new Mac Pro this year. And to be honest, the whole concept of a Mac Pro goes against the design philosophy of Apple Silicon. The whole point of those chips is to maximize efficiency by having everything on-die or very close to the chip. For example, the M2 Max has like eigh…

> This is why Thunderbolt eGPUs don't work - the M1 and M2 can't actually write to the memory on the GPUs.

I thought the major reason was simply lack of drivers.

When I consider that I can use direct mapped M.2 storage over Thunderbolt; or use 100GBit network cards over Thunderbolt 4 (with a PCIe adapter) I wouldn't think that I was limited to mapping memory in the SoC.

It’s crazy how far ahead Apple is getting in the laptop game with these new chips. I have the first gen MacBook Pro with the M1 Pro (ok maybe they’re not winning the naming game), and it’s a perfect computer. Battery life is literally all day, every single action is instant, I have zero regard for many apps or tabs I have open. It’s just perfect. I have literally traveled with just a 30 watt anker brick for my phone…

> It’s crazy how far ahead Apple is getting in the laptop game with these new chips. Sure, but developing with Java up-to-16 is much slower with M1/M2 due to ports not being available, and Rosetta having to emulate. Datapoint: We develop plugins for Confluence and it’s about 1 minute to load each page. I don’t think developing Java 11 is a corner case of using a Mac.

The Java ARM versions don’t work for you?

Ultra since pro is the baseline adjective. Not that I find the naming any good but Max v Ultra would have been more of a head scratcher.

I assume Max is better since there’s nothing higher than the maximum.

Which is why it's more of a head scratcher. Pro The Max is a Pro with (up to) double the number of GPU cores (and memory controllers), the Ultra is two maxes stapled together: https://arstechnica.com/gadgets/2022/03/apples-m1-ultra-tape...

That's when I realize how much my weird hardware preferences set me apart: I mostly care about an OLED screen and ECC ram. Then, a touchscreen supporting pen entry, and a good keyboard (with the edit keys like home/insert/pageup/pagedown directly accessible, bonus is there's also printscreen) especially if it's not a foldable or a tablet. Apple's got good CPU and battery life, but unless the core features are present…

No, not weird, it is called having good taste. For OLED that means DC dimming not PWM dimming - big difference. And with all of the Ryzen Thinkpads there is no excuse for not having ECC when all of the Ryzen mobile CPUs they're using already support it. I don't get the touchscreen thing, but you can always use one of those artist pads via USB and not affect your screen and be decoupled from the rest of your system (U…

What laptop would you recommend that use DC dimming with OLED? Also, does this compromise color accuracy? (I was under the impression that PWM was used with OLED partly because OLED's color accuracy diminishes at lower brightness levels, but I'm not sure where I read that.)

I have Asahi Linux installed on mine, it works great including the GPU, I’m mainly developing for ARM64 AWS Lambdas now as well so it’s nice having the same arch. Some things are still missing like webcam, microphone and speakers, but the headphone Jack works and Bluetooth is OK just a bit choppy, incredible project.

I know this isn't an Asahi Linux thread, but I cannot help to ask about it. Plus I am big fan of Alyssa Rosenzweig's work (and Justine Tunney), so I pay close attention to Asahi Linux (and LibCosmo/politan) progress. First, it's great to hear from Real World people like you about their Asahi Linux experience. It sounds like the baseline is done and now they will pick away at the remaining pieces. Real question: What…

I have a ThinkPad with Linux on it that I bought for programming and software development and a 16" Macbook Pro w/ an M1 Pro chip that I bought for photography.

I only use the Macbook Pro. The speed, battery life, coolness (to the touch), and quietness make it extremely difficult to have any desire to pick up the ThinkPad.

But I'd still be more productive with Linux.

For me MacBookPro with M2 chips would be perfect if the 13in model allowed 64GB RAM. My workflow requires me to run Docker (intel images) heavily with several containers. Having a virtualization layer is pretty resource consuming. Usually the Docker + containers I use take around 5GB RAM alone. Under that configuration I've found 32GB to be just within the limit of usability. 16GB are just not enough. Also, for some…

What software are you using that doesn't have ARM versions available? I think it goes without saying that a machine with an ARM processor is not going to be ideal if you're frequently working with x86-specific software.

I've needed some scientific software that still doesn't have ARM64 libraries available, so thus are stuck on x86. RStudio, for example, has a lot of dependencies and only recently starting offering experimental support for aarch64 on Linux.

What is your Linux laptop giving you that your MBP doesn’t? And how does it hurt your productivity? Genuinely curious as I don’t see how it can be any different.

For my experience, as a longtime Linux user who got a MBP: I really miss the desktop environments available on Linux. KDE is great, and even Gnome beats MacOS. You can't even move windows between desktops with a keyboard shortcut on MacOS. The desktop experience on MacOS is a "death by a thousand cuts" situation. E.g. Popup dialogues will rearrange your windows (e.g. if the popup is wider than your window, to remain…

I’m so sick and tired of macOS and wishing Xcode will run on Linux so I could switch in a heartbeat.
