To coincide with Computex 2014, Intel launched three new unlocked processors based on the Haswell architecture. The processors are the Core i7-4790K, the model we're testing today, the Core i5-4690K, and a special edition dual-core Pentium model to celebrate Intel's 20th anniversary of the Pentium processor.
The Core i7 4790Ks we're testing today came with a marketing nickname, Devil's Canyon. The processor was designed specifically for overclocking and features a 4.4GHz TurboBoost speed, HyperThreading, as well as knobs to adjust everything from cache speeds to BCLK dividers.
With a base clock speed of 4GHz that increases to a maximum turbo frequency of 4.4GHz at stock settings, the 4790K is Intel's flagship enthusiast processor. The 4790K will work with existing Z87 motherboards with a BIOS update, and is compatible out of the box with all Z97 motherboards. The 4790K is Intel's highest clocked quad-core CPU, yet it still boasts features such as integrated graphics and an exceptional dual-channel memory controller.
Two major differences set the Devil's Canyon CPUs apart from the original Haswell K-SKUs: updated thermal interface material (TIM) and extra capacitors on the CPU package. While the boost in CPU speed means that the 4790K has a TDP 4W higher than the 4770K, the upgraded TIM should prove to deal with this situation.
Pricing and Availability
The 4790K is priced at $340 at most online retailers; however, we purchased our CPUs from two local Microcenters, which have in-store specials as low as $280. The 4690K retails for $240, and the special edition dual-core Pentium edition (G3258) retails at $75.
The boxed 4790K carries the basic Intel CPU cooler, a warranty manual with sticker, and a free trial of McAfee LiveSafe. The standard warranty on the 4790K is 3 years. However, if you are worried about overclocking causing damage not covered under Intel's standard warranty, you can purchase Intel's Performance Tuning Protection Plan (PTPP), which covers any damage from overclocking. The Intel Performance Tuning Protection Plan offers extra protection at the low cost of $25; as long as you purchase the PTPP within one year of the purchase of the processor, Intel will replace your CPU one time due to damage caused by overclocking.
