Benchmarks: Single and Multi-Core

Intel only has itself to beat in the single-threaded PiFast benchmark and Haswell's more-efficient architecture is enough to open up a gap at the top of the chart. The Core i7-4770K and i7-3770K both turbo up to 3.9GHz, but the Haswell chip is able to complete the task eight per cent quicker.
This isn't a monumental gain - Sandy Bridge, Ivy Bridge and Haswell all remain closely matched - but the sub-10-per cent improvement gives the Core i7-4770K the fastest stock-clocked PiFast result we've ever seen.

Eight per cent faster than Ivy Bridge appears to be the early theme. The multi-threaded Cinebench test once again highlights Haswell's efficiency, but herein lies what could be deemed a snag for extreme enthusiasts. Intel's getting more from its four hyper-threaded cores, but the company's hexa-core Core i7-3960X scored over 10 points in the Cinebench test a couple of years ago.
Further evidence that Intel isn't looking to shatter benchmarks, but rather focus on honing the architecture to be both leaner and faster. Though, there's no reason why a six-core Haswell offering can't come into being at some time in the future.

wPrime is a number-crunching benchmark that stresses all available cores. Once again, the Core i7-4770K tops the chart but there's not a lot separating the three most-recent Intel generations. Architecture refinements can only go so far when brute force is called for.
