Intel’s unlocked Devil’s Canyon processors finally see the light of day at Computex 2014, after being first introduced at the Game Developer Conference earlier this year.
After divulging details regarding Devil’s Canyon at the Game Developers Conference earlier this year, Intel has finally unveiled the CPU. The manufacturer is launching two new products: a Core i7 4790K and a Core i5 4690K.
Both processors are fully unlocked and feature higher base as well as turbo clocks. The Core i7 4790K has a base frequency of 4.0 GHz (with all four cores independently clocking at 4 GHz) and a turbo frequency of 4.4 GHz, while the Core i5 4690K is clocked at 3.5/3.9 GHz (core/turbo). The Core i7 4790K has 8 MB cache while the Core i5 4690K has 6 MB cache.
One of the major changes in Devil’s Canyon is a new thermal interface, which Intel calls Next Generation Polymer Thermal Interface Material. The new thermal interface allows for more transistors on the die, and will work with existing cooling solutions. Overall, Intel claims that the new thermal packaging allows for better overclocking.
Intel has touched on the performance increases in Devil’s Canyon, mentioning that in certain use case scenarios, the i7 49790K CPU is 35 percent faster than the Core i7 2700K, which was launched three years ago.
Although the new CPUs are pin compatible with 8 series motherboards, Intel is recommending they be used with the recently launched 9 series boards. Intel cites that the TDP increase, which is now 88W from the 84W on earlier Haswell processors, as the main reason for incompatibility with 8 series boards. However, the manufacturer has stated that any 8 series board that can deliver 88W to the CPU can run Devil’s Canyon CPU. All 9 series boards by default deliver 88W.
Intel hasn’t announced pricing yet, but has mentioned that Devil’s Canyon processors will be available from later this month.
Devil’s Canyon isn’t all Intel is announcing today, as there is also a 30 year anniversary edition Pentium CPU, which will also be available later this month. The LGA 1150
socketed Pentium processor has a 3.2 GHz base frequency, two cores, 3 MB cache and will work with both 8 and 9 series motherboards.
