The third gen Ivy Bridge Core i7-3770K can't really be described as a consumer orientated processor. With 8 threads and four cores its capabilities are better aligned to server use. For price insensitive consumers that want the best of the best, this is currently one of the fastest processors available. The PassMark Single Thread score of 2080 points put the 3770K right at the top of the pack in terms of raw processing power and real world performance. The GeekBench and PassMark scores of 17210 and 9653 are within 20% or so of the best we have ever seen. Despite the near record breaking processing throughputs the 3770K is only rated at 77 TDP, which is also very reasonable by historical standards. For typical consumer use there are better value propositions out there. [May '13 CPUPro]


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]
