Any performance comparisons with Raspberry Pi boards? How does this RISC-V CPU stack up against them?

Not great; VisionFive appears to be significantly less performant. https://browser.geekbench.com/v5/cpu/compare/17159543?baseli...

afaict rbpi cpu has vector instructions?

if so, i wonder how much that contributes to the difference...?

Earlier quoted context omitted.

I know what 10W feels like because the Jetson Nano draws that, and Raspberry 4 is 7W with GPU+4 cores saturated. You will need a heatsink on the Visionfive if the GPU does what I hope it does. The Raspberry 4 GPU is only 1W vs. 5W on the Jetson Nano! I'm hoping for a 2-3W GPU on the Visionfive and then you'll need a heatsink for MMO gameplay no question about it. Longevity is now crucial as hardware peaks, heat kills…

4.4 W is the figure given for the SoC on full load. They also give a lower figure that's 3.x W for full load with the GPU off. It won't need a heatsink, because with its power draw it won't get above 70C even on full load, while the chip is built for industrial temperature range in operation.

Do you have a URL for those 3.xW and 4.4W claims?

For longevity 60C is better. I'm talking multiple decades at constant permanent full blast here.

I received mine weeks ago. There are several desktop images but various issues reported from no display output, to only 1080p supported. To this image or that one working. Important note, the later images require an updated to uboot and SPL, either with the bootrom or a serial connection. It's a mess at the moment!

yea, thats for sure, but i think a lot of promise too...

from my cursory testing it seems gui performance is much better than hifive unmatched (window manager, apps, web browser)

Likewise. I believe mine arrived about the 29th. Haven't broke the shrink wrap yet.

I have a sifive "unmatched" board sitting here collecting dust, cost me $700 then.

Most projects turned out ARM based after I bought it.

The site is not working, any price of this board? What's its market, e.g. ip camera? I'm still interested in lower cost ready to go risc-v boards.

Any reason why it's collecting dust? I have a few RISC-V boards and I haven't had any issues with them other than having to compile almost everything from source.

I’m looking to buy these boards; recently I bought one on eBay. I plan on using them to add to FOSS projects’ buildfarms. The first one I got from eBay is now running Postgres buildfarm.

Please let me know if you’re interested in selling me yours.

Explaining Computers "StarFive VisionFive 2 RISC-V SBC review, including a demo of an engineering release of Debian, and of Python GPIO control" https://www.youtube.com/watch?v=ykKnc86UtXg

It's sad how 'being able to actually use GPIO pins in software' is an achievement for an SBC. But I do applaud StarFive for actually seeming to throw some support behind their boards. We have been spoiled with Raspberry Pi the past few years prior to the shortages. I wish another vendor could get close to Pi's position to give more competition in terms of support and documentation.

>> it's sad how 'being able to actually use GPIO pins in software' is an achievement for an SBC

Yeah, but with an OS and MMU you don't get to just write to a port or other registers. The plumbing has to be in place.

> 1 Processor, 1 Core, 4 Threads

Any idea why StarFive went with this choice for an SBC? I remember POWER7 also having 4 SMT, but it felt right for a superscalar multi-core CPU.
