Is this in par with or faster than comparable ARM, ADM or Intel processors at the same price level?
Or more performance per watt?
Or an instructino set that makes a lot of operation super fast?
What is the upside?

rwjm's package build benchmark shows it as 25% faster than a comparable µarch Raspberry Pi 4.
It's been some time since Intel or AMD had similar products: I guess something around Pentium III, Pentium M, or early Core 2.
Prices are a function of production volume (and features / quality, but mostly volume).
The Pi 4 is if course a mass-market product and is cheaper. Arm's own "Juno" A72 dev board is $10,000, which is 20x more than this SiFive board.

It (and Sipeed, Pine64, Milk-V boards with the same SoC) is the fastest RISC-V hardware, per core, currently available.
The $2500 Milk-V Pioneer is overall faster due to having 64 cores (and 128 GB RAM, 32 PCIe lanes), but is slightly slower per core.
You buy these early dev boards because you want or need RISC-V for some reason, not because you want the cheapest fastest hardware of any kind.
We are still years away from boards where they are interesting to people who are only interested in laptop or higher performance classes.
The key part is 'dev' - it's for people doing development on the platform.
