CPU slower than 4 as said, but even Jetson Nano is slower that the mad performance per watt of the 4.

BUT the GPU is apparently better which would make this THE SBC.

I will test my 3D MMO engine and give exactly what is what once I receive mine, should be a couple of days.

The Raspberry GPU has a serious cache problem, it can't render a triangle at 60FPS in 1080p!!!

But 100 non-instanced animated characters (each with a unique weapon in hand) at 60FPS and low res (800x600).

Jetson (1/2 Nintendo Switch GPU) does 300 at 60 FPS in 1080p.

If the Visionfive 2 is either:

  - 100+ at 60 FPS and 1080p
  - 200+ at 60 FPS and 800x600

I'm going ALL IN on Risc-V (my own VM for scripting the engine) and StarFive (buy a few to use as demo for the MMO instead of Raspberry 4/Jetson Nano).

>the mad performance per watt of the 4.

More like bad than mad.

This SoC is far more efficient, using just 4.4w on full load and achieving some 80% of rpi4's cpu performance at a much lower power, with no need for a heatsink.

We'll see, if you need a heatsink for this here is one I bought which should fit: http://www.enzotech.com/cnb_s1l.htm

Not going to debate the gflops/w yet, but Raspberry 4 cores are also around 1W each and they kick ass compared to even M1 (much worse OFC, but per $/openess they still win imo)

If the SoC in rpi4 was any good, it wouldn't need a huge heatsink to not throttle.

The reality is that it draws around 10w more often than not.

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 electronics slowly but oh so surely!

Edit: Do you have a URL for those 3.xW and 4.4W claims... Then I think we wont see 100+ but cache can still be larger so you can have 100 at 1080p and that is enough for mainsteam adoption and replacing all other computers (Switch, PS4, XBOX, phones and pads etc.)!

The future belong to those that compile!

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.
