![]() ![]() If the overclocking headroom delivers on top of that, enthusiasts might be able to hit 4.7-4.8GHz on standard cooling." The other tweak to the Haswell core is a great many additional capacitors, which have been integrated to smooth power delivery at higher currents. ![]() Overclockers reported that removing Haswell's lid could boost clock speeds by several hundred MHz. First, Intel has changed the thermal interface material from the paste it used in the last generation over to a new Next Generation Polymer Thermal Interface Material, or as Intel calls it, "NGPTIM." Moving Haswell's voltage regulator on-die proved to be a significant problem for overclockers since it caused dramatic heat buildup that was only exacerbated by higher clock speeds. The new chip is the Core i7-4790K and it packs several new features that should appeal to the enthusiast and overclocking markets. Enthusiasts weren't terribly excited about either core but Intel is hoping its new Devil's Canyon CPU, which launches today, will change that. Haswell may have delivered impressive gains in mobile, but it failed to impress on the desktop where it was only slightly faster than the chip it replaced. ![]() Both chips were just incremental updates over their predecessors. Meanwhile, here's some useful coverage of the latest overclock-friendly Z97 motherboards, just in case you're looking to accessorize.MojoKid (1002251) writes "Last year, Intel launched two new processor families based on the Haswell and Ivy Bridge-E based Core i7 architecture. There's also a Core i5-4690K to look out for, priced at $242, which notches base and turbo speeds up by 100MHz compared to the current product - not a huge gain, but enough to send a message that Intel isn't entirely preoccupied with Broadwell and ultra-portables. The $339 price tag is identical to what you'd pay for the existing Core i7-4770K on Newegg (base clock: 3.5GHz), so it's definitely worth holding onto your cash until the end of the month. Such a part is just weeks away, however, in the form of the refreshed Haswell Core i7-4790K, codenamed "Devil's Canyon." The new chip shifts from 4GHz up to 4.4GHz in turbo mode, with the only downside being a slight increase in wattage from 84W to 88W - a change that might be partly mitigated by Intel's use of a better thermal interface material underneath the lid of the CPU. Sure, we've seen 4GHz base clock speeds before, but never in an Intel chip. ![]()
