Spacemit X60 (K1) SPECINT 2006 Benchmark
I ordered a BananaPi F3 last week and it arrived on May 6th. Using the opensbi and kernel compiled from armbian , replace the rootfs with archlinux.
Surprisely, I found this core has Zicond extension which was ratified in late 2023, then I also add this extension to compiler. And then benchmarked on LLVM 17 + GCC 14.
The result is shown below.
LLVM 17
GCC 14
For GCC 14, I tried different -march settings.
Note: b is zba_zbb_zbc_zbs. Only write b here to simplify the isa string.

Comments
As an in-order micro-architecture, the result is normal, as I expect. It’s not so good compared to some other cores, such as T-Head C910, but the ISA extension is good for developers. It is an excellent device to come in 2024 for the RISC-V ecosystem, especially for RISC-V Vector software development. I have used it to benchmark my chacha20 RVV patch for openssl, and it has been merged today.
