The Cinebench 11.5 is a well-threaded piece of software and this test is able to leverage on any extra processor cores, courtesy of Intel's HyperThreading technology. The Ivy Bridge CPU outperformed the Sandy Bridge processors by margins in the range of 8%. This winning performance underscores the superiority of the new architecture of the Ivy Bridge CPU and was almost on-par with the Sandy Bridge-E based i7-3820! Only the hex-core monster Core i7-3960X was able to pull ahead of the comparisons by a notable degree.
For the video encoding test administered by Handbrake 0.9.4, the Core i7-3960X pulled in first while Intel i7-3770K is a distant second with a loss margin of 25%. Its performance profile in this test is similar to that of Cinebench, besting the Sandy Bridge CPUs by similar winning margin range (of about 7%) and running neck-to-neck with the Core i7-3820.
