I'm not surprised at the outcome. These Ampere system single core/thread performance is pretty low and that is where you feel it. The OS/software simply cannot allocate the threads across enough cores effectively to make up for this difference.
This is why things like the Apple M Series feels so fast, because while they don't win the multi core performance especially when going up against a 80 core beast like this, they have single thread performance exactly were it is needed.
Maybe we will need 80 cores in future, that is cool but for daily home use it is still just way too much for what we need.

> I work at Red Hat. Mostly on AArch64 support in several projects.
So an ARM developer, working for a major Linux distro vendor and trying to dogfood their work, used the closest thing to an ARM workstation that Linux can run on.
What other alternatives would you suggest? The various Apple Silicon or Snapdragon laptops that have their own well-documented problems running Linux? A smartphone running as a desktop?
There aren't very many ARM-based options that are even feasible for use as a developer desktop, even if the software did work correctly.

Apple M series is also aarch64 architecture, isn't it? Could you explain more why you expect Ampere to be slow but M series to be fast?
rwmj 1 days ago [-]
Apple design their own Arm-compatible cores from scratch. Ampere use a modified Arm Neoverse N1 core. In addition, the Ampere server that Marcin is using is about 6 years old, and would have been tuned for core count over single thread performance (good for web serving). Basically Arm's own cores aren't nearly as good as Apple's at the best of times, and having a 6 year old server makes things even worse.
jdub 1 days ago [-]
Because they're designed for different things.
Ampere's primary focus is running lots of simple tasks concurrently, at relatively low power, with lots of I/O. So, many tens to hundreds of cores, not too fast, at lower power draw than amd64, with lots of PCIe lanes for storage and network.
Apple's primary focus is user experience and power efficiency. That's why you'll find a handful of fast performance cores and low power efficiency cores, along with graphics acceleration to drive high resolution displays.
To expand on what others have said, aarch64 merely defines the set of instructions that the CPU can perform. That has an impact on how you design processors, but you can still design multiple completely different processor architectures with different performance characteristics that all implement the aarch64 instruction set.

I guess my impression was that in this case the yak shaving was the real work, or at least a part of it?

I'm not sure why the author didn't attempt to dive deeper into the error message he saw. amd_vcn_dec sounds like it's an issue with the GPU's video decoding logic. If there's a timeout when trying to process a decode request, it may be that power management for the GPU is buggy somehow. Given that this is a server build and idle power consumption is likely not a big deal, I'd suggest pinning the GPU power state to see if it resolves the issue (see amdgpu.ppfeaturemask and amdgpu.runpm kernel parameters).

I see the problem, but I don't see a clear analysis on the actual source of the problem. I assumed the issue was mainly single core performance, but he is also suggesting context switches could be the cause?
So could you fix that with a new scheduler? Or you just need another SoC with better single core performance? I could imagine that the latter already exists, just not in soc with >16 cores.
My naive view is that such high core count system comes with tradoff on core size and interconnect/memeory bus complexity.
And I mean.. my phone is a middle lower end device and for sure I can play youtube videos (maybe in a popup as well) and run the browser without noticing that much difference from my laptop.

neobrain 1 days ago [-]
Unlikely. I've been daily-driving the predecessor (X13s). While it's usable and technically all drivers are there, it's far from "without pain" due to endless number of small but annoying quirks. Just to give you an idea: boot fails 4 out of 5 times, external displays aren't recognized unless plugged in/out several times, sporadic resets during overnight sleep, etc. On top of that speakers will sound prohibitively tinny due unimplemented software-side speaker protection. I haven't tried T14s, but at least the audio issues will still apply there.
Apple devices supported by Asahi are a far more polished experience.
The effect is understated there, perhaps because Apple speakers are actually somewhat usable without this feature. For the X13s, the speakers might as well not exist in the current state on Linux.
Without pain? I mean, there is pain when using Linux. It just works better than, say, Windows.

It's a bad solution compared to having the hardware just enumerate itself like PCI does. (No one uses the firmware supplied DTs because they're usually broken.)
M95D 1 days ago [-]
All IBM PC clones had (or emulated) the same 8253 timer, 8259 PIC, 8237 DMA controller, 8042 keyboard controller, CMOS RTC, 8250/16550 serial port, standard IDE/PATA, standard framebuffer addresses, standard PCI and ISA register addresses, FPU was always at IRQ13, mouse at IRQ12, RTC at IRQ8, LPT at 0x378, PC speaker at 0x61, etc.
All this doesn't require any enumeration and was still standard until BIOS/CSM was removed. PCs could use the same IDE driver for 30 years of hardware! All chipsets were compatible, from 386 to today's SATA in compatibility mode.
ARM made the mistake of not standardizing anything beside CPU instructions (and even those aren't always the same - see the mess armv7 created with thumb, thumb-ee, simd, neon, crypto acceleration, etc.). Of course it needs enumeration. But x86 is now catching up with the mess. Just wait...
Enumeration instead of standardized hw is bad, but I prefer the least worse device tree.

M95D 1 days ago [-]
But ARM has PCI, including it's enumeration. For the many other devices (timer, uart, I2c, PCI controller itself) no enumeration is possible - you can't enumerate searching for a timer without having a working timer - only a hardware description stored somewhere is possible. The device tree is the most logical, easy to understand, fixable, updateable and extendable way to describe hardware. It doesn't have executable code like ACPI does, and that's also one of the good things.
Let's take an example. Raspberry Pi doesn't have a RTC, but it has GPIO header. You add a RTC module on that header, one of several models of RTCs.
With the device tree, you load an overlay with some parameters and a kernel driver module. And it works.
How do you do that with ACPI? Ask the manufacturer for a UEFI update that scans for dozens of RTC types on each I2c bus? Good luck with that! What happens 5 years later when the board is long abandoned (not Raspberry's case, but think of an ordinary chinese manufacturer)?

And to have a giant amount of RAM and high speed networking at the same time.
Also a chance to learn some of the serving stack for inference.
In the end, it's worked out. It is power efficient, it shipped with a vendor supported Ubuntu. I can run Qwen 3.6 27b reasonably well on it. And it basically does everything I need applications wise.
