The benchmark table below serves to illustrate that the status quo hasn't really changed since we reviewed the Core i7 4770K last year. So let's talk Devil's Canyon performance. We needed to use low-profile Corsair Vengeance RAM in order to attach our relatively monstrous cooler, but otherwise, the Z97I Gaming AC was as easy to work with as a standard board with no performance deficit. We're not entirely convinced by the tangible benefits of the Killer networking, but it does at least suggest premium parts across the product. While omitting key features of the Z97 chipset - for example, support for the new PCI Express SSD formats - the Z97I Gaming AC impressed in many respects, not least with its onboard Soundblaster audio chip, and four SATA-3 6gbps ports.

The supplied PC featured a mild 200MHz overclock to the i5, but we're looking to push the CPUs much more here, and despite its minuscule dimensions, the board offers much the same overclocking capabilities as much larger platforms. We're using the new Devil's Canyon processors on an MSI Z97I Gaming AC mini-ITX motherboard - the same base platform found in the Nightblade small form-factor PC we looked at last week. On top of that, additional capacitors are found on the base of the chip in order to provide smoother, more consistent power delivery to the processor.įirst, a quick word about our test set-up. To achieve this speed increase, Intel made changes: a new thermal interface material (TIM) attaches the processor die to the metallic heat-spreader covering in an effort to address claims that the firm had skimped on this important element in last year's Ivy Bridge release.

Memory: 2x 8GB Corsair Vengeance Pro DDR3/1866MHz. GPU (dedicated): Nvidia GeForce GTX 780 Ti. CPU #2: Core i5 4690K (quad-core with hyper threading, 3.5GHz/3.9GHz turbo, 6MB cache). CPU #1: Core i4 4790K (quad-core with hyper threading, 4.0GHz/4.4GHz turbo, 8MB cache). Out of the box, this is the fastest quad-core CPU Intel has ever shipped and it's quite a technical achievement, bearing in mind that some of last year's i7 4770Ks failed to overclock to this level. However, the new i7 4970K is intriguing: stock speed moves from 3.5GHz to a stunning 4.0GHz, while turbo hits an even more impressive 4.4GHz. On the face of it, the Core i5 4690K doesn't look like much to write home about - it's got the requisite 100MHz clock-speed increase over last year's model, moving up to 3.5GHz base and 3.9GHz with Turbo Boost active. The chips are the same but the surrounding packaging is redesigned with overclocking in mind, addressing an area of the market Intel struggled to satisfy with last year's offerings.ĭevil's Canyon takes the form of new, unlocked K-series Core i5 and i7 processors, accompanied by the release of an unlocked £50/$75 dual-core Pentium Anniversary Edition we'll be looking at soon. However, Devil's Canyon - the new enthusiast products - are different. These CPUs are available right now and while remaining as powerful and as great value as ever, the refresh simply amounts to Intel bumping up clock speeds across the board by 100MHz and selling the new chips at the same price as the older ones they replace. Shrinking transistors isn't as easy as it used to be - not even for the mighty Intel - so to fill the void left by Broadwell's no-show, we have the imaginatively titled Haswell Refresh. This year we were expecting to see the 14nm tick, codenamed Broadwell. Last year's Haswell, manifesting in the top-end Core i7 4770K, was a tock. A new architecture is released with a tock, before it's shrunk down the following year onto an even smaller fabrication process - the tick - making it even more power-efficient, before the cycle begins again. The strategy's known as the "tick-tock" model. Year after year, Intel has produced ever more capable, more efficient CPU architectures with relentless pace.
