Question x86 license value quickly dropping

[soresu]

V1 was the one and only core with 256b goodies.

#1. SVE1 tho.

#2. A64FX has 512 bit SVE1 units 🤘

Gonna be interesting to see what Monaka has when it finally lands.

A64FX has 512 bit SVE1 units

That's borderline esoterica.

From the ARM technical reference manual:


Seems like just 128 bit.

Yes, sounds like 4xNEON and 2xSVE128 like I said a few days ago when it was reported it had 6 128 bit ALUs.

To be fair, to the average person so is V1.

I can rent V1 instance just fine. Like a few clicks is all it takes.
A64fx is a unicorn chip.

Ohhh, didn't realise it was in SaaS servers.

Didn't somebody say otherwise, ie: 6×NEON/SVE

Yeah there's a small little company called Amazon, they kinda run a cloud business. Kinda.
They even have a custom Si with 64c V1 on it!

Lmao, Adroc

Unless I completely misread it there's nothing to suggest that in what I posted.

Or are you reading from another part of the X925 Tech Ref Manual (TRM)?

• Implementation of the Scalable Vector Extension (SVE) with a 128-bit vector length and Scalable Vector Extension 2 (SVE2)
• Integrated execution unit with Advanced Single Instruction Multiple Data (SIMD) and floating-point support

This doesn't suggest anything beyond the fact that both NEON (ASIMD) and SVE1/2 at 128 bit vec length is supported by the vector execution units.
