Benchmarking the original Raspberry Pi Model B
Yesterday, I used the FORTRAN double precision Whetstone benchmark to assess the new Raspberry Pi 2. The results are rather impressive.
For the sake of completeness, I spent this morning dusting off my original RPi, installing the same operating system (Raspbian) and compiler (gfortran) to repeat the test.
The result – an average of 150,962 KIPS over 10 runs of 100,000 loops, compared with 276,369 on a single core for the RPi 2. Which on this single, somewhat flawed (albeit interesting) benchmark, makes the RPi 2 around 1.8 times faster than my original model B, or 7.2 times faster across all four cores.
