Qualcomm hyped these CPUs since years showing results in benchmarks. We still don't have laptops with Snapdragon X Elite but meanwhile competition is releasing improved chips, see M4.

I wonder if it won't be a little late when the laptops will be finally available to consumers.

Laptops with this chip are not shipping yet, so it’s a bit early to judge performance.

There are some early benchmarks which put its performance behind iPad: - Snapdragon X Elite (2,574 / 12,562) - iPad M4 (3,630 / 13,060)

What device was this benchmark run on?

This is great news for those invested in ARM CPUs. I, for one, purchased a Lenovo X13s when it first came out for around 1,900 EUR. Unfortunately, my experience with it on Windows was subpar, and it was even worse on Linux. At the same time, I bought my wife a MacBook Air (not sure if it was an M1 or M2), and it was snappy and very pleasant to use. I bought the Lenovo based on the hype from benchmarks, and it seemed like a capable system initially. However, I couldn't tolerate all its limitations and ended up returning it, as it performed no better than a Chromebook I had bought earlier.

I'm hopeful that Snapdragon will offer an alternative ARM platform for laptops that can handle more than just browsing. As consumers, we need options, and the more, the merrier. I'm still undecided about the short-term success of Snapdragon. For now, I'm betting/waiting on the MacBook Air with an M4 as my daily driver, although I do prefer the Lenovo ThinkPad format.

This is very cool, sure the performance isn’t as good as Apple’s stuff but a reasonably performant processor with official Linux support is very cool

The metric I'm interested in is mostly system performance, not CPU performance.

How fast can a system compile my projects that is.

Since we’re talking about Linux support, the iPad benchmarks seem irrelevant. It’s a completely different kernel.

Asahi Linux benchmarks on an M3 MacBook Air would be the closest thing here.

I am excited about the prospect of Linux on another powerful aarch64 platform like Snapdragon Elite.

But, as far as I can tell from the diagram on the link shared, you will boot into EL1 and not EL2. This means that you cannot run a hardware accelerated VM on KVM (via something like qemu).

This makes a Snapdragon Linux laptop not as useful. BTW Asahi Linux on Apple Silicon enters on EL2 which allows qemu+KVM.

Entering on EL1 instead of EL2 seems to be be an outstanding issue with current Snapdragon based Linux laptops too. Can anybody correct me here if I'm wrong ?

> In short, our roadmap for the next six months includes work in these areas:

> End-to-end hardware video decoding, on Firefox and Chrome

> Implementation of the libcamera-SoftISP camera solution

> GPU and CPU performance optimizations

> Power optimizations (Suspend/DCVS)

> Making our firmware openly available (in Linux-firmware)

> Access to easy installers (Ubuntu and Debian)

"Making our firmware openly available (in Linux-firmware)" is a big one. How are firmware updates currently distributed ? People using Linux Laptops probably don't want to be signing into some Qualcomm website to get latest firmware updates. Also downloading firmware updates from some random link either would not instill a lot of confidence either.

I feel these 2 big items need to be addressed before Linux on Snapdragon can be a truly attractive option.

I used a Huawei laptop and it's great. Huawei's build quality is significantly better than Asus. Not Apple level, but maybe half way there. Lenovo is also pretty good in quality (depending on the model though). Asus laptops are either cheap plastic or extremely thin metal that flexes - even on top end models. They also have a bad track record with support for their Tinkerboards. Not sure how the country of origin mat…

Technically they might be fine, but there are geopolitical reasons to avoid chinese products.

I guess you need to avoid using any phone, tablet or laptop then unless all its chips are built in Taiwan. I know Apple Silicon is built there but what about other chips in their hardware?

They won't be late. There's a significant amount of people who cannot use macs for work. If Qualcomm succeeds with the x86 translation, they'll still be the only real option for that segment, even if they're behind M4.

(Also likely for people who don't have $$$ to throw around for hardware)

You can't benchmark a chip. It all depends on how much power and heat dissipation the actual device can provide. When the MacBook Pro comes out it should run circles round the iPad. And there are no Snapdragon X devices yet
