Faster than ARM A-77: https://www.phoronix.net/image.php?id=2021&image=sifive_p650_1_show https://www.phoronix.net/image.php?id=2021&image=sifive_p650... . Performance comparable to Apple Icestorm architecture, the 'efficiency' cores in M1. Considering A-710 is the fastest ARM core currently available and its successor will only be available next year, SiFive is just a few years before real competition starts in an arena currently dominated by ARM.
This will be beautiful to watch.

- zozbot234 5y agoIt will be interesting to see a comparison on power-efficiency as well as performance. RISC-V implementations have shown a pretty sizeable advantage wrt. power use in the past, and we don't quite know how this advantage compares in these larger, performance-focused designs.
- DeathArrow 5y agoPower efficiency and performance depends very much on process node. If Apple bought all future 3nm capacity from TSMC, good luck trying to compete.
- dmitrygr 5y ago> just a few years before real competition starts Are you assuming the competition will just sit and do nothing?
- GhettoComputers 5y agoGood enough” matters more than benchmarks. They can make supercomputers but it doesn’t matter to someone who wants a $100 computer.
- dmitrygr 5y agoAll riscv thingies i see today are decidedly not $100. I do see plenty of arm designs running linux under $10 though
- LeifCarrotson 5y agoThere are several cheap ones listed here: https://riscv.org/exchange/ https://riscv.org/exchange/ such as the $30 Sparkfun Red or the $20 Lofive boards. Those are for running an RTOS, not Linux, but they compete with Arduino, mbed, teensy, and other ARM Cortex M series microcontrollers. A price target of $10 is something you'll only hit with massive scale-up.
- dmitrygr 5y agoI was responding to "someone who wants a $100 computer" Those are not computers
- DeathArrow 5y agoRaspberry Pi is $50.
- StreamBright 5y agoSure, have you actually used one? There some challenges with the software support of RPIs especially model 4 and GPU drivers. I would like to see a platform (potentially RISCV) that has great software support and I could finally use one of these devices as a replacement for TV set top boxes running Android.
- klelatti 5y agoIf the issue is with GPU drivers then why would a RISC-V cpu make any difference? There is a lot of wishful thinking that using RISC-V magically makes all of the SOC more open. It doesn’t!
