I use both of these boards every day. Constantly, as it's my work.
Building my RVV 0.7.1 gcc 9.2 snapshot takes 111 min on the U74 VisionFive 2, 122 minutes on the C910 LicheePi 4A.
Running DotNET "LINQ" test suite takes 4m30s on VisionFive 2, 5m30s on LicheePi 4A.
Doing `emacs --eval '(kill-emacs)' hello.c` takes 0.72s on VisionFive 2, 0.75s on LicheePi 4A. Close, but the C910 does not win.
Yes, the C910 significantly beats the U74 on every micro-benchmark. Dhrystone, coremark, my "primes" test https://hoult.org/primes.txt, memcpy...

It doesn't translate to the real world, at least in the TH1520 SoC, on the LicheePi 4A sbc.
