Arm has another 'most powerful CPU to date' – this time, the 64-bit-only Cortex-X2 for laptops and smartphones

Arm will today unveil two trinities – a family of three CPU cores, and a family of three GPU cores – for system-on-chips powering future laptops, smartphones, smart home entertainment equipment, and similar gear. The CPU cores are the Cortex-X2, A710, and A510, which are Armv9 compliant with SVE2 features. In fact, we're told …

"It also supports 128-bit-length vectors"

Interesting.

The entire x86 world is still trying, unsuccessfully, to shed its 32-bit past and become fully 64-bit, and here we have ARM boldly going where no x86 processor has even dreamed of going : to 128-bit.

Does that have anything to do with video, perchance ?

Re: "It also supports 128-bit-length vectors"

They are talking about SIMD, which Intel already has up to 512 bits wide depending on model.

Re: "It also supports 128-bit-length vectors"

Ah, see this article about the introduction of Arm's SVE, which can support SIMD vectors that are 128 to 2048 bits in length, though this implementation for smartphones goes to 128. x86 can go up to 512 bits (see AVX)

SVE started life as vector extensions for Arm supercomputers, and is now coming to client chips in the form of SVE2 (which includes SVE).

Well that was an eye-opener for sure.

Thanks for the link.

ARM A710 or ARM710

It's a bit confusing they've gone full circle on the naming. ARM710

Re: ARM A710 or ARM710

Yeah I know. The A510 kept making me think of the Acorn A540, too.

Will it ever lose it's Acorn/Archimedes link?
