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 puts 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 very low by historical standards. For typical consumer use there are better value propositions out there. [May '13 CPUPro]

MORE DETAILS

The 3930K has an outstanding multi-core performance profile, almost as good as you can buy at any budget, which considering its relatively reasonable price tag really make it stand out from the crowd. The reason for the extraordinary multi-core benchmark scores is down to the 3930K's six cores. Having six cores effectively results in a 50% lead over quad core cpus and a 200% percent lead over dual core cpu's. Typical desktop users rarely use more than two cores simultaneously thus rendering the additional four cores largely redundant for consumer use. In terms of regular use this CPU will offer virtually no better real world performance than the leaders in my Desktop CPU Group Test. For server orientated workloads the 3930K offers both outstanding performance and superb value for money. [Jun '13 CPUPro]
