Below are the updated charts with the addition of the two freshly tested Hasswel-E models, the i7-5820K and the i7-5930K:

For SuperPi 32M the Ivy-Bridge E models with their higher Turbo speeds remain king of the hill for the high end platforms. Nevertheless when comparing clock per clock the new Haswell-E generation will have the edge due to architectural improvement and the DDR4 generated bandwidth, though out of the box the lower clock speeds for the two new processors are noticeable in this particular test.

When all cores are loaded the architectural improvements of the Haswell-E generation become more apparent. Even with lower clocks the new high end models from Intel outperform their predecessors easily. The 200Mhz higher clocked i7-5930K logically outperforms the 5820K; however the latter retails only a tad higher than the Devils Canyon i7-4790K. When comparing those two in a full multi-threaded environment the new Haswell-E’s make mincemeat of the flagship mainstream processor.

When testing in Cinebench the single threaded performance, raw clock speed is king. The 4GHz core speed, together with the 4.4GHz Turbo speed of the i7-4790K makes it perform outstandingly, though since modern applications are more and more multi-threaded there's no denying that the new i7-5820K is a solid bang for the buck processor when opting for Intel's latest high end platform. Easily outperforming the previous generation i7-4930K model, even while running at lower clocks (100 MHz on the core clock & 300MHz on the Turbo core clocks)
