Comparing against a raspberry pi 5 is kind of overkill. While a Pico 2 is close to computationally equivalent to a cray 1 now (version 2 added hardware floating point), the cray still has substantially more memory - almost 9MB vs 520k.

For parity, you have to move up to a raspberry pi zero 2, which costs $15 and uses about 2W of powerm

A million times cheaper than a cray in 2025 dollars and quite a bit more capable.
