AMD Bulldozer Dual-Interlagos Benchmarks On Linux

However, this is not the fastest C-Ray result we have encountered on our open and collaborative benchmarking platform. A Dell PowerEdge server that's packing four Intel Xeon X7550 CPUs that each have six-cores and Hyper Threading with a 2GHz base frequency with 2.4GHz Turbo Frequency and 18MB of L3 cache, is the current winner in that category as shown by doing this dynamic comparison.

In another Bulldozer test using Himeno, which is a linear solver of pressure Poisson using a point-Jacobi method and is not too multi-thread friendly, the numbers aren't too impressive with the 32-core server coming in at just 88 MFLOPS due to its lower clock speed.

A third test result we have right now for the dual AMD Bulldozer-based Opteron system also shows impressive performance in the Parallel BZIP2 Compression test. There is also other result uploads from the "AMD Eng Sample ZS182045TGG43_28" for SciMark 2 computations and Stream memory tests. More may also come, but these are just the results so far we have been able to verify as valid/authentic.

In the months leading up to AMD's official Bulldozer introduction we'll likely see more results too, based upon the rapid growth of Phoronix Test Suite and ambitious, independent users opting-in to publicly submit their test results to the OpenBenchmarking.org repository, so stay tuned to OpenBenchmarking.org (you can also follow @Phoronix and @MichaelLarabel to be notified of the most interesting bits as I manually watch the stream of data). This also happened back in December with Intel Sandy Bridge too, but back then Iveland/OpenBenchmarking.org was only in closed beta testing.

For those interested in AMD's Bulldozer CPUs, based upon the data so far, it looks like they should be well supported under Linux. This though shouldn't be too surprising since the CPUs are compatible with existing motherboards of the same socket types and there is no graphics support to worry about like there is with Fusion or Sandy Bridge.
