The i7-950 is a first generation Core processor which is now three generations and four years old. The 950 was included in the group test as a reference for how fast processors were back in 2009. This particular generation of processor heralded the 4 core 8 thread configuration that Intel has been kitting its top end processors with ever since. In terms of real world performance based on single core horsepower (most applications are still unable to make use of multiple cores concurrently), with a PassMark Single Thread score of 1320 the i7-950 is approximately 50% slower than its modern day equivalent, the i7 4770K[Feb '12 CPUPro]

MORE DETAILS

The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]
