Their top model still only has "Up to 228 GB/s" bandwdith which places it in the low end category for anything AI related, for comparison Apple Silicon is up to 800GB/s and Nvidia cards around 1800GB/s and no word if it supports 256-512GB of memory.

> Their top model still only has "Up to 228 GB/s" bandwdith which places it in the low end category for anything AI related, for comparison Apple Silicon is up to 800GB/s Most Apple Silicon is much less than 800 GB/s. The base M4 is only 120GB/s and the next step up M4 Pro is 273GB/s. That’s in the same range as this part. It’s not until you step up to the high end M4 Max parts that Apple’s memory bandwidth starts to…

As I stated this is the top Qualcomm model we're talking about, not the base which is significantly lower.

Given their top model underperforms the most common M4 chip and the M5 is about to be released it's not very impressive at all.

Even the old M2 Max in my early 2023 MacBook Pro has 400GB/s.

It doesn't say which generation of core is it. Are they the same as the one in Elite Gen 5?

Has Microsoft actually pushed for the ARM changes? Because I don't believe Qualcomm can do it alone.

How's the compatibility? Are there any apps that don't work that are critical?

Surface Pro 11 owner here. SQL Server won't install on ARM without hacks. Hyper-V does not support nested virtualization on ARM. Most games are broken with unplayable graphical glitches with Qualcomm video drivers, but fortunately not all. Most Windows recovery tools do not support ARM: no Media Creation Tool, no Installation Assistant, and recovery drives created on x64 machines aren't compatible [EDIT: see reply, I…

Does Remote Desktop into the Surface work well?

When I'm home, I often just remote desktop into my laptop.

I'm wondering if remoting into ARM Windows is as good?

Does anybody know if the X2 supports the x86 Total store ordering (TSO) memory ordering model? That's how Apple silicon does such efficient emulation of x86. I'd think that would be even MORE important for a Windows ARM64 laptop where there is so much more legacy x86 software going back decades.

Does anyone have benchmarks for Rosetta with TSO vs the Linux version with no-TSO? I guess it might be a bit challenging to achieve apples to apples, although you could run a test benchmark on OSX and then Asahi on the same hardware, I think? I've always been curious about just how much Rosetta magic is the implementation and how much is TSO; Prism in Windows 24H2 is also no slouch. If the recompiler is decent at tra…

People who have worked on the Windows x64 emulator claim that TSO isn't as much of a deal as claimed, other factors like enhanced hardware flag conversion support and function call optimizations play a significant role too:

As someone who has used the Snapdragon X Elite (12 core Oryon) Dev Kit as a daily driver for the past year, I find this exciting. The X Elite performance still blows my mind today - so the new X2 Elite with 18 cores is likely going to be even more impressive from a performance perspective! I can't speak to the battery life, however, since it is dismal on my Dev Kit ;-)

Ironically, the app I've had the most trouble with is Visual Studio 2022. Since it has a native ARM64 build and installation of the x64 version is blocked, there are a bunch of IDE extensions that are unavailable.

Yes, it's the same Oryon V3.

AFAIK Windows on ARM is completely pushed by Microsoft (obviously they're limited by their own competence) and Qualcomm has been kind of phoning it in.

“Multi-day” battery life sounds wild! That’s probably the biggest thing for users. It would be good for Apple to get some competition because their M-chips seemed so far away from everything else.

Any battery life claim needs to be aligned with the consumer-class operating system and application layer (iOS, Android, etc). Multi-day battery life on a non-Google-Pixel Android device with typical usage would be interesting.

Wait, you got one of those Dev kits? How? I thought they were all cancelled.

Edit: apparently they did end up shipping.

Have I had any app compatibility issues? To quote Hamlet, Act 3, Scene 3, Line 87: "No." The Prism binary emulation for x86 apps that don't have an ARM equivalent has been stellar with near-native performance (better than Rosetta in macOS). And I've tried some really obscure stuff!

That's certainly not what the reviews say.

Adobe apps that ran fine on Rosetta didn't work at all on Prism.
