Take control with the 6th Generation Intel Core processors codenamed "Skylake-S". The i5 6600K is the flagship processor of the Skylake-S line-up that features exceptional performance that is increased by up to 22% and offers 6x faster storage bandwidth for quicker media access, all this means for an all-round more responsive PC. The 'K' prefix shows that this CPU is Unlocked and has overclocking enabled this is great news for extreme gamers and enthusiasts. Improved overclocking is supported on the 6700K when in conjunction with Z170 chipsets only, it uses the BCLK (base clock) overclocking feature

In regards to the lovely 6600k itself. It arrived in a very colorful box, much like its bigger brother the 6700k. You notice from the onset the box is somewhat lighter and this is a result of intel removing the stock cooler for the CPU. As a result an aftermarket cooler is required, but generally this is no big deal as the stock cooler that came with the older CPU’s and locked CPU’s can run fairly warm and loud. For our build the Krakan X61 was used.
Aside from that we got a small manual and a sticker.
Of course the performance is the most crucial aspect and for that the CPU absolutely flies. For the motherboard we had it paired with the ASUS Maximus hero Z170 motherboard and a pair of Corsair DDR4 3200 Mhz sticks of ram and the CPU absolutely flew. Manually overclocking we dialed in a stable overclock of 4.7 Ghz @ 1.35 volts, so in all the chip performs nicely.
Out of curiosity as I own a 4690k, we compared the two systems at 4.6 Ghz in some titles: Crysis 3, Shadow of Mordor, Tomb Raider, Fary Cry 4, GTA 5 and Witcher 3.Read more ›
The obvious choice would be RAW POWER and going for the i7, but in reality, "bang for buck" just isn't the same. The i5 6600k, especially with superb overclocking potential was the most logical of the two candidates, particularly for a gaming build. Straight out the box this is one fast processor and I had the pleasure (for lack of a better word!) of using the integrated Intel HD530 for a day before my GPU came. It's not actually that bad... It managed World of Warcraft on low/mid at a steady FPS which was passable for a processor! Of course I would always recommend a dedicated GPU but if you, like me, need to wait on postage, you can definitely build a system with just the processor for a day or two of light gaming.
Installation was a breeze, just need to be delicate like all processor installations.
Skylake "K" processors such as this one, do not include the Intel Stock fan, so bare in mind you will need to look at your own cooler. Personally I combo'd this with a Hyper 212 Evo, and it stays super cool.
Hope that helps, have fun and let me know if I can answer any questions :)
ASUS Z170 Pro Gaming
Corsair Vengeance 16gb 3200Mhz CL18(I think, can never remember timings)
Sapphire R9 290 Tri-X oc (already had)
Coolermaster Hyper 212 Evo (how unoriginal)
Easily the best processor I have ever had (I came from AMD, what do you expec, to be honest they are great value), easily stable overclock to 4.6Ghz with minimal settings tweaks, just CPU core voltage which is around 1.36 V - i'm sure I could get it lower, but I haven't had the time to run AIDA64 yet on these voltages.
This is the flag ship of the current i5 processor line. The 6600K works with both DDR3 and DDR4 RAM, so for those upgrading an older generation system, their RAM will still be usable while still retaining the option to upgrade to a newer generation of RAM (DDR4, if their motherboard supports it). Good price for performance allows for the user to not break the bank while building a gaming centric PC.The performance of the i5 6660K is similar to a more expensive i7 processor in gaming situations. While the i7 does use more threading (twice as much), there are very few PC games that can actually take advantage of this making the i5 a good choice when building a gaming specific PC.The chip itself allows for 16 PCIe 3.0 lanes. This translates into how many PCIe devices can be used at the same time and how fast they can be controlled which makes for a scenario where multiple PCIe GPUs can be used at their top transfer speed of 16x for one and 8x for two.The K series of processors from Intel allow for overclocking. This means the user can choose to use after market cooling systems to then overclock their chips to see better performance than stock.
This processor uses the LGA 1151 CPU socket. For those upgrading from an older generation chip this means the will need to purchase a new motherboard and possibly RAM in order to use this chip. This can be expensive to replace so many components all for a single new pin in the chips connection. While the performance will be better than the last generation, it may not be worth the price of all new gear to see this performance. No longer does Intel include a heatsink with their new CPUs, so the user will have to purchase their own. While they are not too expensive, that basically means out of the box this can not be used unless a purchase was made for a heatsink along with this item.

Its great, very high performance, the overclocking ability makes it that much more recommended, but just annoyed that Intel released the new i5 7600K straight after my purchase. :)Published 11 days ago by Joe C.
