sandy_bridge-e

In this second part we will analyze in detail the performance of the Intel i7-3960X with Sandy Bridge-E architecture.  Several tests will be run with various software, specific tests on the memory, CPU frequency, 3D and consumption scaling and overclocking. Very interesting are the comparison tests the Intel i7-980X.

CPU frequency scaling

Another test that we conducted on this processor has up to verify the scalability of the operational frequency of the CPU from a base frequency of 3 GHz up to a frequency of 5 GHz in steps of 500 MHz As software we used the excellent compression/decompression 7-Zip program and the popular Cinebench R 11.5 rendering program that uses the Cinema 4D rendering engine. The results were very interesting and not entirely discounted. Below you can see the graphs created for the two software used:

7zip

Looking at the first graph, 7zip, you can see that all CPUs have an excellent performance as the frequency increases. The new CPUs manufactured by Intel has more than linear scalability, indicating that the internal architecture is ahead of the others. Distance is very high when we are at 5 GHz.

cinebench_11.5

Totally specular situation with Cinebench test that shows the same results seen with 7zip. The new Intel CPU has a much steeper than linear performance increase, and the advantage increases as we go up in frequency.
