![]() ![]() ![]() Overall seconds indicates MP efficiency.Īs with the single core version, average Pi 4 performance gain, over the Pi 3B+, was just over 2 times, but more similar compared with 32 bit speed, this time the latter being somewhat faster on some floating point calculations. None of the test functions are suitable for SIMD operation, with the simpler instructions being used. There can be some significant differences from the single CPU Whetstone benchmark results on particular tests due to a different compiler being used. Performance is generally proportional to the number of cores used. Measured speed is based on the last thread to finish, with Mutex functions, used to avoid the updating conflict by only allowing one thread at a time to access common data. Multiple threads each run the eight test functions at the same time, but with some dedicated variables. ![]() Many of these benchmarks run using 1, 2, 4 and 8 threads, with others executing programs on all available cores via OpenMP.
