Quad Processor / SandyBridge-E Support

Hello again,

Even though my inquiries regarding multi-core support remain unresolved, I'd like to bring to your attention that when running the benchmark on the new SandyBridge-E platform which has 4x processors, 8cores, 16threads for a total of 64 threads (which is what Geekbench is said to support) the benchmark never seems to utilize more than half of the processor cores.

Obviously this results in really low scores that fail to characterize the performance accurately. In addition to the SandyBridge-E, the Westimere-EX also returns scores that are obviously inaccurate.

I've attached an image of the processor utilization when I ran the Bench on the quad SandyBridge where you can see that only half of the cores are being utilized.

Thanks in advance for your assistance.

   Thanks for your message, and I'm sorry it's taken this long to address the core utilization problems under Windows. Geekbench 2.3.4 was released today which should fix some of the problems with core utilization on systems with more than 32 cores. Could you download Geekbench 2.3.4 and let me know if it helps?

   Thanks,
   John

   I'm just now getting back to this testing and I've tried 2.4 on the SandyBridge-E platform and I'm still only getting 50% utilization of the processors. :-\
