For "Linux kernel compilation speed" they have compared a 16 GB model with 64 GB model for achieving 102.60% improvement! It's so funny =)

Would increasing the RAM really make that big a difference in terms of kernel compilation time? It feels to me that 16GB should be plenty for any sort of caching that will speed things up.

Yeah if you think about it in lower levels. Many optimizations use memoization to save clock speed. Therefore, you almost always need more memory to speed things up.

Cool, now compare it to an M2

Cool, now show me upgrading your M1 to an M2.

Does it matter? I have a Threadripper 3970x and an M1 Macbook Air. For anything that can't use more than 4 cores, the M1 crushes it. The Threadripper also draws over 100W at idle.

Whatever AMD and Intel have right now are completely irrelevant, and I say that as one of the biggest haters of OS X there is.

I'm not trading in my workstation for a Mac Studio or whatever, though, because I'm guessing AMD's 5nm chips will probably perform even better than the M1/M2. Plus games. Games are nice.

I so badly wish these things had TrackPoints :( the patents have expired...

The IBM Keyboard Trackpoint has evolutionary paths towards being a tiny trackball while retracted down, the trackball locks and pops up a functional joystick. The problem with the Trackpoint is it feels superslow, superheavy on the fingertip compared with glidetouch trackpads.

After Apples announcement of M1, I feel like it is mandatory for such a laptop test to discuss power per watt and for how long you can game on the 11 vs 12th gen processor. I also feel like it is worth mentioning that 12th gen laptop is priced ~ $150 over the 11th gen. If you're coding against an online build system and 11 last an extra hour (or whatever), it's a no-brainer to stick with the old one.

You can't game on M1 or Mac AFAIK

Lots of people just don't game at all. Also, a lot of people like me prefer different gaming and work setup (and different rooms) in order to achieve better work-life balance. I build games on my M1 machine, just don't play on it.

The freedom of running Docker on a laptop without heating it to 60c is too tempting, unfortunately. My Macbook will get 2-3 hours of battery life over my Thinkpad, but my Thinkpad also doesn't burn my palms with regular use. It's a game of tradeoffs, but I rarely find myself reaching for the Macbook if I've got a desktop close by. Maybe that's a skewed perspective though. I have yet to try the Pro/Max chips seriously…

Man, the heating on my MacBook is insane. I have a Thinkpad with on board Nvidia card, beefy CPU, etc, and it can play gfx intense games at 4k and still sit in my lap comfortably. Meanwhile my MacBook from work gets risking-burns-hot from just screensharing on a Zoom call.

Is this an arm MacBook? It sounds a lot like an Intel one.

That's super exciting, but I'm not familiar with Xcalibyte. are they a good and reputable maker?

Is frame.work a good and reputable maker? Not saying they won't turn out to be, but they are still young considering the space they are in. Similar holds for any other hw maker that is only starting out!

Or any maker that starts using RISC

I've played with an AMD 6800u laptop and I would say it's the ideal x86 laptop chip right now. Normal usage at the 12w mode or light gaming at 20w mode was super impressive. Even though 12th Gen Intel chips have made great performance gains Intel is still relying on unsustainable high turbo boosts to get the benchmark numbers. I just recently stumbled across these two otherwise identical laptops. https://psref.lenovo…

Since this is Hacker News and a lot of people here runs Linux, I want to remind everybody to hold your horses before you tested Linux on these machines. The machine that I'm currently using comes with a Ryzen 6800H CPU and LPDDR5-6400 RAMs, made by Lenovo. On Linux, the builtin keyboard don't work because of IRQ problems (See [1], a fix is also available at [2]), and it constantly spams out "mce: [Hardware Error]: Ma…

> On Linux, the builtin keyboard don't work because of IRQ problems (See [1]

The exact problem is that an IRQ/ACPI workaround is not needed anymore on modern Zen platforms, and it (the workaround) now breaks compatibility. It's already in linux master, and will be released for v6.0

Commit message of the fix:

    commit 9946e39fe8d0a5da9eb947d8e40a7ef204ba016e
    Author: Chuanhong Guo 

    ACPI: resource: skip IRQ override on AMD Zen platforms

    IRQ override isn't needed on modern AMD Zen systems.
    There's an active low keyboard IRQ on AMD Ryzen 6000 and it will stay
    this way on newer platforms. This IRQ override breaks keyboards for
    almost all Ryzen 6000 laptops currently on the market.

    Skip this IRQ override for all AMD Zen platforms because this IRQ
    override is supposed to be a workaround for buggy ACPI DSDT and we can't
    have a long list of all future AMD CPUs/Laptops in the kernel code.
    If a device with buggy ACPI DSDT shows up, a separated list containing
    just them should be created.

I went from saying, "if only they had an AMD" to getting a different machine in ARM and now im saying "if only they had ARM". I never realized how much heat, vibration, air blowers negatively affected me before. A framework laptop with some type of ARM or ARM-like cpu could do a lot with the space savings on cooling.

Apples M1 only worked because everything is in one chip. Very different from the goals of framework. There aren't any vendors offering M1 competitors either.

That’s not true in any way?

The M1 Air is a wonder as far as I'm concerned. It's very thin and light, fanless, yet I can happily do java dev on it all day and I'm not lacking in capability or waiting around for build and test runs. It rocks.

Are you running your apps in docker?

Should I?

I have docker-desktop for the things I need it for - building the odd linux native image, or running testcontainers for postgres, same as we do when building on linux - and it works great.

But for the day to day stuff, no.
