Should have published some of this data long ago. But better late than never. I ran some very simple integer and floating point benchmarks on all the parts I could find that I have BASIC running on.

Yes, we just got a BASIC running on the Arduino Zero - SAMD21, and we are looking for beta testers, and gauging interest in adding this. We intend it to be a free download.

Sure there are Coremark numbers published by all chip vendors. But Coremark is copyrighted and takes a little configuring and only in C. Mine are not intended as an expansive benchmark, but as a quick test that can be implemented in a few minutes on nearly any device or language.

Floating point test

dim x as single
while x>1
  i=i+1  ' -- count iterations -- about 138K

Integer test

while i

And the results

Not all these parts became products, but were designed as special versions for OEMs.

The last are the PC's I use most of the time, and those PC's are running the ARMbasic interpreter (which is at least 10x slower than compiled). QBasic is a tokenized interpreter and quite a bit slower than ARMbasic which compiles to interpreted opcodes.

ARMbasic can be run from the command line on nearly any PC, maybe someone wants to expand this,
