Intel Core i7 4960X EE CPU / Asus X79-Deluxe Motherboard Review

The clock-per-clock comparison comes in the form of two single-threaded benchmarks that are run by each processor operating at the same frequency of 4.40GHz. Using single-threaded benchmarks allows us to take core count out of the equation and give an insight into any architectural performance differentials.

Despite its smaller amount of cache, the 4770K is able to outperform Intel's Ivy Bridge-E flagship processor by almost 4% in the single core Cinebench test. It is clear that Haswell has the greater architectural performance and not even substantially larger amounts of cache can overthrow that.

On a clock-per-clock basis, the IVB-E 4960X is just over 5% faster than the SB-E 3930K. An extra 3MB of L3 cache on the IVB-E chip is partly to thank for its improved performance, but architectural updates also assist.

The same picture is painted with Super Pi's single-threaded workload. Haswell's 4770K is around 4.8% faster than the IVB-E 4960X. The 4960X is, in turn, around 2.5% faster than the SB-E 3930K.
