![]() ![]() We tested the Core i7-4790K in an Asus Z97-Pro motherboard with a SilverStone Argon AR03 air cooler. It's designed for motherboards that use the Intel Z97 chipset, and will also work happily in older Z87-based motherboards, although you may need to update the board’s firmware to enable it. It also has the same 8MB of Level 3 cache as the i7-4770K, which is shared equally between all the processor's cores.Īs with other Haswell processors, the Core i7-4790K is compatible with Socket LGA1150 motherboards. ![]() Like the Core i7-4770K, the Core i7-4790K benefits from Intel’s Hyper-Threading technology, which means that processor’s four physical cores are split into eight logical cores, theoretically improving multitasking performance and performance in multi-threaded applications. ![]() This means the i7-4790K will run slightly hotter and consume slightly more energy than its predecessor, so will be in need of the extra cooling provided for by its design. The chip has an 88W thermal design power (TDP), which is slightly higher than the Core i7-4770K’s 84W TDP. The Core i7-4790K is based on a 22nm process and has four CPU cores, as well as an integrated Intel HD Graphics 4600 graphics processor. Otherwise, there is little difference between the chips. The i7-4790K can operate at these higher clock speeds thanks to extra capacitors that help deliver power to the die and a new thermal interface material to improve cooling. The new chip has both faster base and boost clock speeds than its predecessor, the Intel Core i7-4770K, with a base clock speed of 4GHz and a Turbo Boost of 4.4GHz, compared to 3.5GHz and 3.9GHz. The Intel Core i7-4970K was 25% faster than the Intel Core i7-3770K on the second pass, so if you have an Ivy Bridge processor you’ll need to give it a good overclock in order to keep up with a stock 4790K CPU.2014’s Core i7-4790K, codenamed 'Devil's Canyon', seems to be a response to these complaints. The extra 500MHz turbo boost speed on the Core i7-4790K Devil’s Canyon processor meant that we were seeing a performance uplift of 12.6%. The Core i7-4770K came in with 67.53 FPS on pass one and 17.11 FPS on pass 2. This application scales across many threads and is ideal for processors with Intel Hyper-Threading or a bunch of cores.īenchmark Results: The x264 HD v5.0.1 benchmark showed the Intel Core i7-4790K had good runs with 75.07 FPS on pass 1 and 19.26 FPS on pass 2. ![]()
