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]


Processor Rankings (Price vs Performance) October 2018 CPU Rankings.

We calculate effective speed which measures real world performance for typical consumers. Effective speed is adjusted by current prices to yield a value for money rating which is geared towards gamers. Our calculated values are checked against thousands of individual user ratings. The customizable table below combines these factors to bring you the definitive list of top CPUs. [CPUPro]
