I have a C906 and while it's fun, it's very very slow by 2021 standards: single core, scalar in-order @ 1.0 GHz with no L2$.
The upcoming BeagleV is a lot faster (I have the beta): quad core, dual issue in-order @1.5 GHz (TBD) with 2 MiB L2.
I'm expecting (guessing) that the triple-issue OoO P550 would be 5-10X faster at iso-frequency, but if history repeats it'll be four+ years before we see it in silicon for sale.

The C906 core in Allwinner D1 SoC will make an excellent competitor to the Pi Zero when it ships on the promised $10 to $15 Sipeed and Pine64 boards later in the year -- and that will be a real price where you can buy as many as you want, not the "$5 but you can only buy one" fake Pi Zero price. The $99 "Nezha" board with the D1 is of course not value-competitive for that performance level. It's a manufacturer's (i.e. Allwinner) prototype board for volume manufacturers such as Pine64 to use to develop software while they work on their own board. The same goes for the HiFive Unmatched. It's not intended for volume production, it's for developers to use to prepare software for later high volume boards (including the BeagleV).
