It's TSMC N6. What does that information benefit you? We're still talking about a boutique chip that's not going to outperform anything from the past decade's worth of amd64 products.
Even knowing nothing about performance, knowing that it is N6 means it probably isnt particularly power efficient (as compared to leading edge x86/ARM).

According to that graph, the P870 has 80% of the performance of Ice Lake.
We can compare performance with other TSMC N6 designs. Even more so if we also know the area and power.

This isn't some U74. This is P870. Its published performance data is no joke.
I was curious to see how far RISC-V still have to go from a microarchitecture stand point, but even in the same silicon process level, there are other things to take into account: the RISC-V compiler support, and something which is really new: since RISC-V is a non-IP-lock worldwide standard, assembly writting is much more a reasonable thing.
Knowing it is TSMC N6 unlocks at least this much.
