CPU Performance

I couldn’t get right into it and benchmark the 6700K, especially its CPU performance. I mean with Intel pushing this as a big gaming and enthusiast CPU that is the main focus anyhow. Once I had our test bench setup (this took a while I had a LOT of issues with getting Windows 7 installed) I set our Kingston Fury ram using XMP at its 2666MHz and got to testing. I started off with some encoding in X264 HD Benchmark. Here I run through two tests a total of four times each and then average each out. The results are the average FPS that the CPU was able to encode. The first pass favors clock speed and overall architecture where the second test is a little heavier on higher core count in addition to the clock speeds. So the first test actually put the 6700K right up at the top above the 4790K. The second test favored the 8 core 5960X and all of the past 6 core CPUs from Intel. Even so the 6700K did well, especially when compared to the 4790K that it replaced and the 5775C that I tested just a few weeks ago.


Next I tested using Cinebench, my favorite benchmark. I like this benchmark because it lets us see both a total CPU score as well as a single core score. The single core result is a great way to compare architures, especially when comparing between the 6/8 cores to the 2/4 cores. Here in the whole CPU result we have the 6700K up over the 4790K but still a little behind all of the modern Intel 6 cores going all the way back to the 3960X that is a little old now. The single core result really puts it all in perspective though, the 6700K is the fastest single core result with only the higher clocked 4790K coming close. In fact none of the others tested are even close (1.69 to 2.05). I also included the newer R15 results as I am slowly moving to that as our benchmark. The results are similar in it as well.



Next in Passmark 8 I use the total CPU score to test a variety of the synthetic CPU benchmarks. Here we see that the 6/8 cores are still favored but I was surprised to see the 4790K up ahead slightly as well given our results up until now. I guess the higher clock speeds helped.


Next for real world results I use PCMark 8 as it tests using video playback, browser usage, and word processing for most of its testing. Here we see that the 4790K with its higher clock speed still outperforms in some situations. It’s clear that PCMark 8 favors high clock speeds given how high the FX 9590 ranks as well.


Next I tested with wPrime as a good math compute benchmark. Here the 8 core 5960X dominates but the 6700K does surprisingly well in a firm second place.


Next I test using 3DMark Fire Strike benchmark but to keep it focused on the CPUs performance and not on GPU driver changes I only focus on the physics score. No big surprises here, the 6700K comes in just below the 4790K as well as the 6/8 core Intel’s but is well above everything AMD has as well as the recent 5775C.


Last but not least I run through a few different modern games to see how much if at all the CPU effects actual in game performance. In some games like Bioshock and Hitman the CPU plays a big role. The others hardly change from CPU to CPU. Even then Bioshock seems to be more dependent on clock speeds and Hitman favors more cores. The 6700K performs well in both but the one weird result is that 5775C actually outperforming the 6700K in Bioshock.

I hope everyone is having a nice week. Today Intel launched the first two of many Skylake CPUs at Gamescom. I put the i7-6700K through our tests and find out how it performs!
