A lot slower - roughly 100x - because most of these benchmarks measure FLOPS and the rp2040 doesn't have native floating point, so it has to emulate it, taking it down to 1-3 MFLOPS vs the 160 MFLOPS of the cray-1.
If you compared integer operations it would be a lot closer, but that's not really what the cray was designed for. (The rp2040 at 125mhz * 2 cores is in a pretty similar range)
