The Core i7-4790 is the third upgrade to Intel's flagship quad core hyper-threaded CPU. This version, like its predecessor the i7-4771, gets a 100 MHz bump in stock frequency and additionally the i7-4790 also gets a 100 MHz turbo frequency bump. These improvements (~4%) are marginal and practically impossible to discern in day to day use. Looking at a benchmark comparison between the 4771 and 4790 verifies that there is little difference between the two CPUs. Although the i7-4790 isn't much of a step forward, it's still one of the best (locked) mainstream processors on the market. AMD hasn't been able to compete with Intel on single threaded performance for several years, consequently Intel have no need to push the envelope. Overclockers should wait for the 4790K which is rumoured to be released shortly. ^{[May '14 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]}
