Intel Haswell Refresh Reviewed: Core i7-4790, i5-4690, i5-4590 and i5-4460 Tested

About the same time this year Intel introduced the world to their 4th generation processor aka Haswell, built on the same 22nm technology and using the Tri-Gate transistor technology derived from Ivy-Bridge. The Haswell processors delivered a decent boost in performance in regards to the predecessors. Most special about Haswell was the Fully Integrated Voltage Regulator inside the processor die, allowing finer coarse voltage adjustments inside the processor without the need of a gazillion phases on the motherboard. Maximizing power efficiency was Intel’s main target: this integrated regulator solution was discussed heavily over the internet mainly due to speculations of extra generated heat. With Haswell the Intel HD integrated graphics solution also got a small boost versus the Ivy Bridge solutions; too bad that the Iris Pro with embedded EDRAM is only available on a limited number of Haswell processors as it is a real scorcher and can easily compete and even outperform AMD’s latest Kaveri APU offerings.

Overclocking the Haswell generation was totally different from the Sandy and Ivy-Bridge generation. Haswell turned out to be a mix of clocking the previous released Ivy-Bridge (LGA1155) and the high end Sandy-Bridge E CPUs (LGA2011) on one platform. Loads of gear ratios and memory dividers allowed the OCer to maximize performance per clock.
For daily OC’ers the maximum clock frequencies reached were lower than with Ivy-Bridge; again the heat dissipation issue reared its ugly head.
For the extreme guys Haswell was sadly a return to Intel’s usual Cold bug (+/- -120°C) which is a pity. Nevertheless a good clocking Haswell leaves a similar clocked Ivy-Bridge biting in the dust.
