What happened here? Not only is Blender 50 to 70% faster on Linux, the tables have turned. As the software is still in Alpha 2 phase, it is good to take the results with a grain of salt, but still. For some reason, the Linux version is capable of keeping the cores fed much longer. On Windows, the first half of the benchmark is spent at 100% CPU load, and then it quickly goes down to 75, 50 and even 25% CPU load. In Linux, the CPU load, especially on the Opteron 6174 stays at 99-100% for much longer.

So is the Opteron 6174 the one to get? We are not sure. If these benchmarks are still accurate when we test with the final 2.5 version, there is a good chance that the octal-core 6136 2.4 GHz will be the Blender champion. It has a much lower price and slightly higher performance per core for less complex rendering work. We hope to follow up with new benchmarks. It is pretty amazing what Blender does with a massive number of cores. At the same time, we imagine Intel's engineers will quickly find out why the blender engine fails to make good use of the the dual Xeon X5670's 24 logical cores. This is far from over yet…
