Can't wait for a faster risc-v SBC, waiting for rust builds on my VisionFive 2 drives me crazy.

no need to wait

Other than having RVV, that board is slower than a VisionFive 2, at least for what I primarily do (building software). Yes, even with 8 cores vs 4.

Also the K1 chip offers support for 16 GB RAM, but the RV2 only offers 8 GB. I have 16 GB on the same chip on my LicheePi 3A.

Are you sure about the "slower" part? Because I have both a VisionFive 2 and the OrangePi RV2, and the OrangePi RV2 is way faster in my different tests. Even in single core scenarios.

Yup. For example, Build Linux kernel commit 7503345ac5f5 with defconfig.

When using all the cores the SpacemiT is not much slower, but single core it takes over 1.5x longer.

On other tasks that don't stress the caches so much the SpacemiT can do well.

Best to wait for the RVA23 chips.
