The Intel Skylake i7-6700K Overclocking Performance Mini-Test to 4.8 GHz
by Ian Cutress on August 28, 2015 2:30 PM ESTGaming Benchmarks: Discrete Graphics
Our regular benchmarks for processor reviews consist of Alien Isolation, Total War: Attila, Grand Theft Auto V, GRID: Autosport and Middle Earth: Shadow of Mordor. Rather than the full run of graphics cards from $70 and up, we are limiting here to just the low-end testing on integrated graphics and a full on ASUS GTX 980 Strix assault.
NVIDIA GTX 980
Conclusions on NVIDIA GTX 980
In our discrete test, it is clear that there is not much difference between the games tested.

If we keep dropping the OC multi on Skylake we are going into single-digit clock increases territory from 4GHz stock :)Yeah, I wonder why AT mentioned in their Skylake review about why people are losing interest in OCing despite Intel's claims of catering to it. From the looks of it, their 14nm process simply isn't tuned for 4GHz+ operation but towards the lower clocked but much more lucrative chips for the server and mobile segment.

Then you are deluded. There are edge cases and scenarios that will cause a hardware crash on a Xeon server with ECC RAM at stock speeds, so by your reckoning *nothing* is ever 100% stable.danjw - Friday, August 28, 2015 - link
When can we expect a platform overview? You reviewed the i7-6700K, but you didn't have much in details about them. You were expecting that from IDF. IDF is over, so is there an ETA?MrBowmore - Friday, August 28, 2015 - link

I assume the POV-Ray score is the "Render averaged PPS"?My 2600K @4.4 gets 1497 PPS, so a 35% improvement compared to 6700k @4.4

And of course I mean the 6700k seems to be 35% faster in POV... sigh this needs an edit buttonlooncraz - Saturday, August 29, 2015 - link
POV-Ray has been seeing outsized performance improvements on Intel.From Sandy Bridge to Haswell sees a 20% improvement, when the overall improvement is closer to 13%.
HandBrake improved even more - a whopping 29% from Sandy Bridge to Haswell.
And, of course, I'm talking core-for-core, clock-for-clock.
I suspect much of this improvement is related to the AVX/SIMD improvements.
Just hope AMD focused on optimizing for the big benchmark programs as well as their server target market with Zen (this is past tense since Zen is being taped out and currently being prototyped.. rumors and some speculation, of course, but probably pretty accurate).

One has to remember, that "handbrake" doesn't actually use CPU-resources at all. The process that is actually benchmarked is running x264 codec with certain settings easily accessible by using GUI called handbrake.If x264 or x265 programmers create new codepaths inside the codecs that take benefit of new architecture, it received huge performance gains. But what this actually means is that Sandy Bridge and Skylake actually run different benchmarks with different instructions fed to processors.
Do I care? No, because I just want my videos to be transcoded as quickly as possible, but one should still remember that this kind of real world benchmarks don't necessarily run same workloads on different processors.

When are you going to publish the runthrough of the architechture?! Waiting impatiently! :)NA1NSXR - Friday, August 28, 2015 - link
Sigh, still no BCLK comparisons at same clocks. What would really answer some unanswered questions would be comparing 100 x 40 to 200 x 20 for example.
