Does Graviton3 use the Neoverse V1?
The Graviton2 used the Neoverse N1.
The features listed here match the core:

The N2 misses the bfloat, but it could be that the ARM marketing named it differently:

- dragontamer 5y agoN2 has BFloat16 instructions. EDIT: I probably should have a citation: https://developer.arm.com/documentation/PJDOC-466751330-18256/0000-03?_ga=2.265796748.243487855.1638295737-1927301140.1631220381 https://developer.arm.com/documentation/PJDOC-466751330-1825... Page 50 of 92 shows off BFCVTN, BFDOT, BFMMLA (matrix multiply and accumulate), BFCVT, and other BF16 instructions on the N2. I'd assume this Graviton 3 is a N2 core. But that's just me assuming.
- haukem 5y agoThanks for the document, so the ARM marketing just confused me. ;-) Yes N2 is more likely than V1. N2 has the better PPA ratio. Own CPU core is very unlikely as I am not aware of any rumors which we would have notice before. N2 also supports ARMv9 which is nice.
