Hello Ladies and Gentlemen, My name is McGyver, and you might know me from critically acclaimed reviews about the Dell P2715Q monitor or the Radeon 7870XT graphics card. If Google brought you here, this is a forum about a FREE Source engine mod called Empires. You should try it! Today we are going to look at my new CPU, the Intel i5-6600K Skylake generation. Let me tell you a little history. After several years of only using a laptop, in 2008 I decided to build a gaming PC once again. Back then, the choice was between a higher-clocked dual core and the slightly slower clocked quad-core. I chose the quad and that rewarded me with several years more of usage out I got of this CPU. This month I had to make a similar decision, go for an i5 or an i7 or even a hexa-core CPU? This time I went for the i5, because I do not think that the upcoming advances in multi-threading are worth the additional price tag. Although it feels pretty strange that after seven years I only upgraded from a quad-core to another quad-core CPU. Skylake is the code name for Intel's newest processor architecture and it comes from a delicious 14nm facturing process. After two years Intel finally released CPUs for the desktop based on a new tech, I scantily survived the time I had to wait for it and almost got talked into getting a Haswell CPU. Installation was pretty painless, my Noctua NH-U12P cooler I already used for the Q6600 will serve to cool the 6600K as well. Professionally applied thermal paste. But let's take a look at the performance increase: I used my old Q6600 at 2.7 Ghz and the new i5-6600K was set to a mild overclock of 4.0 Ghz. First let's take a look at just the pure single thread performance with CPUmark99, no fancy new instructions are used here, just raw integer processing power. From 383 to 719 points! That's quite impressive, but doesn't even double the seven year old CPU. Then we try the build in benchmark tool from CPU-Z: Here single threaded performance improves from 740 to 1658 points! Also in gaming, Skylake does deliver: Guild Wars 2 went from below 20 FPS in large World versus World battles to 80+ FPS and that is with higher settings. GTA V FPS doubled in the integrated benchmark from 30 to (possibly GPU limited 60) FPS. Then there is the improvement for people that use full disc encryption (everyone should use that!) Look at that, AES encryption test went from 383 MB/s to 3500 MB/s! Dat AES instruction set integration. And there are the energy savings too: Idle (with dedicated graphics card): 42W down from 100W. My router alone needs 8W! Load with Prime95: 138W down from 180W Conlusion: New CPU better than old CPU, but seven years don't change THAT much. Thank you for your attention.
