> I like the Raspberry Pi RP2040 a lot. It's relatively cheap (around $1 USD) and has tons of on-board RAM - 264 KB in fact! It also has what is called Programmable IO, or PIO.
I wonder how benchmarks would compare between the RP2040 and, say, a Z80.

It would destroy the Z80. It's a 32bit, dual core CPU running at 133MHz. Even single cored it'll thrash a Z80. Heck, I bet you could create a drop-in replacement board for the Z80 using an RP2040.
