For those lucky people who have purchased the SL-6000 (and for those who are thinking of buying it), I have run a benchmark comparison between the SL-5600 and the SL-6000. The comparisons are between the two machines, but among several kernels: two on the SL-5600 and the standard SL-6000 kernel. The table below compares the standard SL-5600 kernel performance with the SL-5600 overclocked (with preemptif) patched kernel and the standard SL-6000 kernel.
The benchmark that I used has been optimized (using GCC compile time paremeters) for the different ARM processors. The goal was to see which GCC optimizations worked best with which processors for different target operations. I did not compile the software (and I can't seem to find where I got them), but you can run your own tests with them: nbench-arm.tar.gz or nbench-arm.zip.
The data was collected from the better of two runs on the SL-6000 and the better of two runs on each kernel for the SL-5600. The original data collected for each kernel can be found here: SL-5600 Standard kernel data, SL-5600 Overclocked kernel data and SL-6000 kernel data.
nBench optimized for ARM version 3 (nbench-armv3).
