Available from OpenBenchmarking.org are some tests of the brand new Raspberry Pi B+ ARM system. The Raspberry Pi B+ was announced last week as the last revision to the original RPi. The B+ board has more GPIO pins, a total of four USB 2.0 ports, a micro SD port, improved audio, and form factor improvements. However, the Raspberry Pi B+ is still using the Broadcom BCM2835 and there's still just 512MB of system memory.
With the Raspberry Pi B+ still using the same SoC with the single-core 700MHz ARM1176JZF-S CPU, these new benchmarks aren't particularly exciting or different from the existing Raspberry Pi "Model B" single board computer. However, some independent party has done some benchmarks of both models using the open-source Phoronix Test Suite benchmarking software and shared the results using OpenBenchmarking.org.
