AmpereOne Sees Last Minute Compiler Tuning Ahead Of GCC 13

[brucethemoose]

Thanks for the tip! I never looked at laptop reviews. The last time I needed to buy one, I went with (the once default choice of) a "Thinkpad", and then my search was simply about finding a good deal on a B-stock or refurb unit.

Now, with Linux support becoming so pervasive, geopolitical considerations might cause me to prefer other options than Lenovo, for my next laptop. Dell has announced plans to eliminate China from its supply chain by 2027.


FWIW, TechPowerUp has a very nice CPU/GPU specifications database. I'll probably always use Wikipedia as my primary source, but TPU's has a nice searchability feature.

Indeed, but notebookcheck hosts actual benchmarks for many games, and they also have desktop GPUs as reference points. The amount of labor put into it is almost unbelievable.


Its unlikely my next laptop will be anything but a 16" Framework (because Framework) or an Asus Zephyrus (since they are overengineered yet so deeply discounted in the US), but I am still going to check with them before pulling any trigger.

No surprise there. No offense to Phoronix, but notebookcheck is the best laptop reviewer around.

I'm fairly certain they are the only website left that maintains a good Windows gpu performance database.

Qualcomm killed off their Centriq server CPU a bit over 4 years ago, just as it was about to launch. That was thought to be done to shore up their financials to stave off a takeover bid by someone.

And, although Nuvia claimed their original mission was to build server CPUs, Qualcomm has stayed very non-committal about whether that avenue would ever be pursued under their ownership. Their initial focus is clearly laptops and presumably phones.

So, it doesn't make sense to even talk about Qualcomm server CPUs, at this time. There's no such thing on the radar, which means a minimum of probably 3 years before such a thing could reach the market.


The present reality we have is Qualcomm contending with AMD and Intel iGPUs, in the laptop market.

I figured there should be some decent reviews of it, but 2 of the 4 professional reviews I found didn't even benchmark the GPU. The other two ran some 3DMark tests, but I presume it was running under emulation and not a native ARMv8 build. The more comprehensive of the two was this one:

I mean Qualcomm and Ampere as seperate entities.

Qualcomm would be competing with Nvidia/AMD/Intel dGPUs whether they like it or not,

What's this "Qualcomm/Ampere" business? Did Qualcomm buy Ampere?

As for using Ampere's CPUs in a workstation, that's nothing new. You can find a couple examples, even as far back as their eMAG CPUs. They're not cheap, however. And single-threaded performance isn't even in the same league as x86 desktops or Apple (which tildearrow listed as a requirement).

We will get ARM-based mini-PCs, though. Again, here's an example of the kind of thing we can expect:

https://learn.microsoft.com/en-us/windows/arm/dev-kit/

That gets you 4x X1 cores @ 3 GHz + 4x A78 cores @ 2.4 GHz. Not to mention 32 GB of RAM and 512 GB of NVMe storage. I'd hazard a guess that it might compete with NUCs from a couple generations earlier.


Hmm... the baseline M-series GPUs aren't really that big, are they? I wonder how well Qualcomm's Adreno could scale up. They've been chasing Apple for quite a while, so they know what they're competing against.

Yeah, I saw the eMAG, but they were absurdly priced testing machines :/. Hopefully they could bring the price down for future desktops.

On ST perf: Many users (especially linux users who's primary workload is compilation) would trade ST performance for tons of MT performance.

On the M1: No its not that big. But the thing is, the M series has a great gpu, and its still terrible for "desktop" GPU performance that Qualcomm would have to pursue, aka windows directx gaming and linux opengl stuff. Its niche is media processing and machine learning on OSX.

Qualcomm would be competing with Nvidia/AMD/Intel dGPUs whether they like it or not, as they cant really leverage the unified memory, power efficiency, or Metal API advantage like Apple can in those niches.

I'm waiting when Ampere will release CPU's with hardware acceleration for virtualization because order 80 CPU core which can run only k8s via containers is not what I want...

Yes, they know what they are competing against and gave up.

Quite the opposite. They bought Nuvia.

the bottom end of Qualcomm's/Ampere's server lineup might work in a desktop.

if you want a GPU heavy SoC like the M1, I can't see anyone making that work. The investment in graphics/compute compatibility would have to be be *enormous*, and again the market is small.

Ampere, please, cheap desktop CPU that can fight M1/M2...

Not happening. Beyond wishful thinking.
