Intel Core i5 6600K CPU Review
Posted by Heath Coop on Thursday, October 22, 2015 - 8:00am
On release day, we brought you a review of Intel’s mainstream Skylake flagship, the i7 6700K. Today, we will focus another Skylake, the far more affordable Core i5-6600K. The new processor architecture based on Intel’s newest generation 14nm process FinFET lithographic technology. It promises decreased power consumption and increased performance. Like its more expensive i7 sibling, the i5 6600K is also features an unlocked multiplier and is sure to be popular with enthusiasts.
One of the most notable new changes is the use of DDR4 memory. DDR4 memory was first introduced with Haswell-E just shy of a year ago. Prices were high and many people stayed away. Since then the prices have dropped and become much more affordable. Where Hawsell was limited to around 2666 MT/s, Skylake bumps that up to a staggering 4133 MT/s.
Skylake also brings Intel latest HD Graphics technology. The Core i5-6600K we are reviewing today features HD 530 graphics and Intel claims that it is dramatically faster than the HD 4000 graphics that came with Haswell.
For Skylake-K, Intel has added more extensive overclocking features, chipset support for NVMe drives. Of course there are the new IPC enhancements that offer up to 10% better performance over Haswell too.
