The timing of this post coming mere hours after industry giant Microchip introduces a monster of a chip is relishable:
> The integrated 240Gb/s [Ed: 30GB/s] TSN-enabled Ethernet switch is far from the chips' only feature: the PIC64HX has no fewer than eight 64-bit SiFive Intelligence X280 RISC-V cores,

Actual speed of those X280's is TBD, but this seems like a huge bump in what's on the risc-v market.
Most of the chips we've been looking at are the open sourced C906, a not particularly fancy early core, open sourced in 2021. It wasn't even the highest offering in that release! https://riscv.org/news/2021/10/alibaba-open-sources-four-risc-v-cores-xuantie-e902-e906-c906-and-c910-jean-luc-aufranc-cnx-software/ https://riscv.org/news/2021/10/alibaba-open-sources-four-ris...
Google talked about using the X280 two years ago, and what they were able to get from it's vector unit,

- camel-cdr 2y agoKeep in mind that the 8 cores run at 1GHz, and have a simple simple scalar exexution, from the product page: - 5.75 CoreMarks/MHz - 3.25 DMIPS/MHz - 4.6 SpecINT2k6/GHz This SOC is mostly interesting for the 512 wide (probably single 512 vector issue) vector extension support. If the price is right this might usable as a nice little low power number cruncher. The lockstep mode is also interesting for industry uses. While possible, it's certainly nothing you'd want to run a desktop on.
