Intel Hyper-Threading Technology: Allows each core of the processor to work on two tasks at the same time providing unprecedented processing capability for better multi-tasking, and for threaded applications.Speed when you need it, energy efficiency when you don't. Intel Turbo Boost Technology 2.0: Dynamically increases the processor frequency up to when applications demand more performance.4-Way Multi-Task Processing: Runs 4 independent processing threads in one physical package.you could clock it lower and the rest higher, albeit it's a little far-fetched.īut let's bullet up some of the primary features and we'll focus on the 47x0 processsors right now: So if you learn that one CPU core is a little weaker. For overclockers it will be interesting to know that each CPU core can be overclocked independently. The frequency gain is expected to be up to 37% for a short time and say 20% in other scenarios. Dynamic Turbo (Turbo 2.0) will allow the CPU power to exceed the TDP value when the rest of the platform is relatively cool. It can alter several stages and levels "per core" in clock frequencies. Depending on CPU load, one or more CPU cores will run above its advertised specification. It has changed as there are several steps in which the Turbo Mode will be utilized. This broken thermal reading for the core temperature should only trouble Linux overclockers or those extensively tweaking their system, but the regression will surely be addressed in due time, and it's not i7-4790K specific.So the processor's Turbo Mode is based on revision 2.0, which makes the Turbo Mode much more dynamic. The only problem at all to report is one that I'm hitting with all Haswell processors right now: when using the default cputemp kernel module for reading the CPU core temperatures, 29.8 Celsius is all that's reported. When popping the Intel Core i7 4790K CPU into a Gigabyte Z97-HD3 motherboard, it booted right up into Ubuntu 14.04 LTS x86_64 and encountered no major problems. It should come as no major surprise given all of Intel's investment in Linux through their Open-Source Technology Center and that their developers have already been busy for over a year on Broadwell with the Haswell support being splendid for the most part under Linux, but the i7-4790K ran without any major issues on Linux. My Devil's Canyon sample just arrived on Monday but I've already been busy running the beast under Linux.
Pricing on the Intel Core i7 4790K is currently about $340 USD from major Internet retailers. Like the i7-4770K, the HD Graphics 4600 top out at 1.25GHz.
The Core i7 4790K has an 88 Watt TDP over 84 Watts on the Core i7 4770K but aside from the higher clock frequencies and thermal/power improvements, the i7-4790K shares much in common with the i7-4770K when it comes to being a quad-core CPU with Hyper Threading, 22nm manufacturing, DDR3-1600MHz memory support, and sports HD Graphics 4600. The Core i7 4790K remains compatible with the LGA-1150 socket and will work with existing Z87 motherboards assuming the motherboard vendor puts out a firmware update, or there's a whole assortment of new motherboards on the market powered by the Z97 chipset. The Intel Core i7 4790K is a performance-focused, enthusiast processor with a 4.0GHz base frequency, 4.4GHz Turbo Boost Frequency, ships fully unlocked for overclocking, and sports a new thermal interface (the "Next-Generation Polymer Thermal Interface Material") and other refinements over the original Core i7 4770K Haswell to make it a better candidate for overclocking and maximizing the potential out of the CPU. Today we're delivering the first public tests of the i7-4790K Devil's Canyon run under Linux.

The Intel Core i7 4790K tops out at 4.4GHz and is quite interesting for PC enthusiasts and performance junkies. Last week at Computex Intel formally announced the Core i7 4790K "Devil's Canyon" processor as a new, high-end, refreshed Haswell part.
