To download the benchmarks, click on the Raspberry_Pi_Benchmarks.zip link, select Save to download to Home (assume /home/pi). This includes the executables compiled, as above, to run on Intel CPUs via Linux and the versions compiled on the Raspberry Pi. The benchmarks and source codes can be downloaded in Compilation time was acceptable at between 8 and 36 seconds. These and the PC based files all produced the same numeric results and mainly the same performance. Both the above cc and gcc (with no Toolchain path) commands were used for compilation. Note, the first four benchmark programs were compiled later on the Raspberry Pi itself. The last three parameters (-march to -mfpu) made no difference to performance, but others are likely to be needed to take advantage of later ARM floating point functions.

In order to execute after transferring, a change to Properties, Permissions is needed to make executable.
Using this, the C/C++ code can be firstly compiled to run on the Linux driven PC, then transferred to the Raspberry Pi via LAN or a USB flash drive. This allows programs to be compiled from a Terminal window. Some of the Linux variety C/C++ source code was changed slightly to compile for execution on the Raspberry Pi.Īfter reading that compilation time on the Raspberry Pi was painfully slow, the programs were compiled on a Linux Ubuntu 12.04 based PC via Rasbian Toolchain using instructions downloaded from Most have also been converted to run under
Original ones run via DOS and later versions under all varieties of Windows. The tests demonstrate 3B+/3B performance improvements (not always), the new thermal characteristics and higher speed LAN and WiFi data transfers.Ĭomprises numerous FREE benchmarks and reliability testing programs, for processors, caches, memory, buses, disks, flash drives, graphics, local area networks and Internet. Full details and results are available from ResearchGate in the I have now run my 32 bit and 64 bit Raspberry Pi benchmarks and stress tests on the model 3B+.
