I would look at JH7110, released earlier this year, used in VisionFive 2, Star64, as well as PineTab-V, and with an excellent official effort towards upstreaming software support[0].
I own a VisionFive 2 and can recommend it.
There's also the TH1520, a newer chip that's a bit faster and has pre-spec V extension. This is available in the Sipeed Lichee Pi4A, but the support for this chip is very green still.
CPU-wise, JH7110 performs between rpi3 and rpi4. TH1520 is faster than rpi4.
Else (GPU, I/O, cryptographic acceleration, hardware video codec acceleration and other peripherals), they are both significantly faster than rpi4.

- FullyFunctional 3y agoTH1520 is definitely not faster than a RPi4, not for normal programs compiled with normal compilers or binaries that will come from your distribution. And no, Bruce, vendor benchmarkering doesn't count. ADD: TH1520 is about twice as fast as JH7110, but as best I can tell, StarFive (JH7110) is more proactive about upstreaming support.
- snvzz 3y agoA quick search in Linux git head for "th1520" returned some results. It must mean there is ongoing work. I hope they set up a webpage to track what's going on with upstreaming efforts, similar to JH7110 has. Notably, boards with TH1520 are just starting to ship, whereas boards with JH7110 were shipping in volume in February.
