That was on a 700 MHz Raspberry Pi 1. On an 1800 MHz Raspberry Pi 400 NEON SIMD the difference was another order of magnitude.

[QUOTE] Comparison - The three 700 MHz Pi 1 main measurements (Loops, Linpack and Whetstone) were 55, 42 and 94 MFLOPS, with the four gains over Cray 1 being 8.8 times for MHz and 4.6, 1.6, 15.7 times for MFLOPS.

The 2020 1800 MHz Pi 400 provided 819, 1147 and 498 MFLOPS, with MHz speed gains of 23 times and 69, 42 and 83 times for MFLOPS. With more advanced SIMD options, the 64 bit compilation produced Cray 1 MFLOPS gains of 78.8, 49.5 and 95.5 times.[/QUOTE]
