That thread concludes 31.4 GFLOPS for HPL running on a Pi 5 at standard clock rates. The only way a Pi 4B gets close to 16 GFLOPS is with significant over clocking. Unfortunately, over clocking also increases power consumption.viewtopic.php?t=358804
30 and 10
or is it
25 and 16?
If the latter is correct and Pi 5 uses 50% more electricity, the Pi 5 is not achieving 2x.
But that GFLOPS is probably not CPU but NEON?
And not all processes can use SIMD.
Unless one's interests are actually solving large systems of linear algebra equations using vector and matrix operations, the main relevance of the HPL is well-tuned stress test for checking whether a computer is currently working according to expected performance specifications.
While Fido mostly uses HPL to generate heat for the dog house, the original idea was to track performance over time to help identify systems in need of servicing. Luckily, that HPL Nagios plugin was never debugged or deployed.
