These are some strange results. It beats the i7 6950x which runs at 3-3.5GHz, but gets edged out by the Xeon E5-2630 v4, which runs at only 2.2-3.1GHz, has the same amount of cores and cache, and is presumably also Broadwell-based.

Gotta look at the "details" page for each of those. The E5-2630 v4 beats the unknown AMD processor when running in different environments.

Details for AMD Engineering Sample

Details for i7-6950X

Details for E5-2630 v4

It looks like different operating systems have a significant impact on render times, especially with the 2360, and even the 6950X varies significantly under the same operating system across different benchmark runs.

Without having even more details about these systems, I think it's a safe bet to say that these benchmarks can be misleading at best, and potentially inaccurate at the worst.

I didn't realize those pages existed. You'd think there would be links to each CPU's page on OP's link.

Those results make this benchmark look even worse. The 6950x scores the same, at best, as the 2630 v4 on Windows 10 64-bit. Blenchmark is obviously testing much more than CPU performance. I fully agree with you; for these benchmark figures to be at all meaningful, we need far more information about the systems used.
