Uppskattning av prestanda för nya AMD Bulldozer

One of the early dual Interlagos results from the 32 cores running at 1.8GHz indicates that its C-Ray time is a mere 25 seconds. C-Ray happens to be one of our favorite multi-threaded ray-tracing benchmarks. What does this compare to? Well, running an easy OpenBenchmarking.org comparison shows just how fast AMD's Bulldozer is looking to be. While there are other software/hardware differences in play too, the 32-core 1.80GHz Bulldozer system's 25 seconds compared to the Intel Core i5 2500K (quad-core + Hyper Threading; 3.3GHz + 3.7GHz Intel Turbo Boost) at 61 seconds or the dual quad-core AMD Opteron 2384 system of ours taking 127 seconds to complete. The Intel Core i7 970 (six cores + Hyper Threading; 3.2GHz Base Frequency + 3.46GHz Turbo Boost) comes in at about 61 seconds too.

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.
