Arm Announces ARMv9 Architecture With SVE2

Doesn't v8 already do that with the Apple M1?

Yes, but that's Apple........

Yes, but that's Apple........

But hey, first-party ARM cores do too. Links demonstrating that have been provided in this thread. "ARM IPC is so bad!!!" is demonstrably not true.

As long as all the software people want to use is mainly written for x86, you can forget about ARM on the desktop. Sorry.

These days, most programs are written in high level languages (C/C++, Python, Rust, etc) with abstraction on CPU specific instructions. All you have to do is port the compiler and the OS and you're good. GTK4 compiles fine on x86/ARM/POWER/S390x/MIPS

Since you're on phoronix, I'm guessing you're using Linux. In that case 99+% of software works perfectly on your Arm machine (if you can find an Arm CPU that works with vanilla Linux). The rest is either monstrous (chromium) or uses x86 asm for hot code path (like VLC's decoder).


In the case of Windows, since every app is compiled by their developers, it's hard to force them to cross compile for Arm, but that's Microsoft's problem.

Yes, but that's Apple........

Still based on ARMv8, though.

Yes, but that's Apple........

The fastest super computer is A64FX. The fastest server is Ampere Altra (yes it beats not only Rome but also Milan). All Arm based.

I did take a look at Altra, but it's more of a parallel solution (AKA no low core count processors)...

Cool, maybe SVE and SVE2 will be the incentive needed to push vector programming forward; and the tools will be further along as more RISC-V V chips come on to the market.

ARM has become a really good processor architecture in the past 3-5 years, which can compete with x64 easily.
Hope the ban on china will drive RISC-V though.. It looks promising..
China / Trade-baned countries have to come up with an alternative to ARM and that´s where we might see really fast iterative development cycles and in the end, maybe a design that delivers more performance / joule and overall better peak performance. But probably 5-8 years away from that, right now.

Arm is expecting CPU performance increases of "more than 30%" over the next two generations of mobile and infrastructure CPUs.

15% performance increase per generation is a good uplift. You know who else can do that? AMD. ARM just told us they won't be making up more ground against x86 any time soon.
