Few days back we saw the first performance tests of Core i7-6850X in comparison with Intel Core i7-5820K and today we have Intel Haswell-E flagship processor in comparison with flagship processor from Intel Broadwell-E lineup, we are talking about Intel Core i7- 6950X  and Intel Core i7-5960X.

The Intel Core i7-6950X is based on the Broadwell-E architecture which is manufactured at 14nm comprised of 10 cores running at a Base / Turbo frequency of  3.00 / 3.50 GHz and HyperThreading enabling 20 logical CPUs, which feed 25MB L3 cache with the support of DDR4 memory controller for Quad-Channel configurations. This processor would come at a price around 1000 euros. For CINEBENCH R15 test, Intel Core i7- 6950X  and Intel Core i7-5960X both are coupled with Asus Rampage V Extreme motherboard with 16 GB DDR4 memory @ 3000 MHz and a GeForce GTX 750 Ti. The Core i7-5960X (22nm) CPU equipped with 8 cores to a Base / Turbo frequency of 3.00 / 3.50 GHz.

Intel Broadwell-E Core i7-6950X Vs Haswell-E Core i7-5960X Benchmark Results



The Intel Core i7-6950X was Overclocked to 4.50 GHz for these test performance, achieving a demanding score of 2,327 points, while @4.00 GHz scored 1,904 points. At 4.00 GHz it translates into performance increment of 19.5% than the Core i7-5960X, although the Core i7-6950X still ran at 500 MHz above the 22nm CPU, so every extra core almost gets 1 % additional performance (although it is slower than a Core i7-4770K). The most notable difference is in the memory test AIDA64 where the writing speed is 37% higher in the i7-6950X (reading virtually unchanged).

Above tests are conducted on pre-release engineering sample (ES) of the Core i7-6950X processor.

The definition of Engineering sample

“A chip revision from within the product development stages, a prototype or beta version. It is a working sample of the planned final product with all its characteristics and properties. Engineering samples are used for the development and evaluation of all kinds of issues related to the chip, like electrical specifications and heat dissipation. They are also sent to the mainboard and component manufacturers to provide ways for them to develop their product around an upcoming production version.”

This is an ES, not the final retail CPU.

P.S: The chip tested against the Core i7-6950X is technically not the 5960X but it’s the Xeon equivalent, which provides almost the same performance with a difference under 1% at most.
