First Intel Core i7-6700K Benchmarks Reveal 10-29 Per Cent Performance Gains

Written by Jon Sutton on Sun, Jul 12, 2015 2:00 PM

Results have surfaced from the first Intel Core i7-6700K Skylake processors sent out to reviewers, revealing performance gains as dramatic as 29.1% over the Haswell micro-architecture Intel Core i7-4790K during certain benchmarks.

The upcoming flagship processor from Intel will be one of two Skylake CPUs launching in early August, the other being the Core i5-6600K. The Intel i7-6700K comes packing four cores and eight threads thanks to Intel’s Hyper-Threading technology, as well as 4GHz base clock speed and 4.4GHz boost, all wih 8MB L3 cache and a TDP of 95W.

It’s set to be an impressive enthusiast-class processor, and one which Intel claim is the biggest generation leap seen in a decade. The comprehensive benchmarks released so far, performed on Sandra 2015, 3DMark, and Cinebench, indicate average performance gains in the region of 10%, with Cinebench R15 OpenGL tests pushing gains as high as 29.1%.

Any programs using single thread compute you can expect to see similar performance to the current-gen processors, but once multi-threading comes into play is when we see the real gains.

While these benchmarks are prior to the proper BIOS and driver updates going live, we can see Skylake is going to provide some significant firepower. It’s worth remembering these gains are over the Core i7-4790K, which is one of the fastest gaming processors in existence today, and puts it roughly in line with the six-core Haswell-E Core i7-5820K.

The expected retail price for the Intel Core i7-6700K is likely to fall in the region of $339. Will you be picking one of the new Skylake processors up? Performance gains in the regions you were expecting?

Actually, I'm waiting for a Xeon E3-1231 v5 (Skylake). Basically an i7 without iGPU (gamers don't need that) but at the cost of just above an i5 model.

If a game averages something crazy like 100 FPS, 10% better performance is only 10 FPS at a $339 pricepoint just for the CPU, not to mention you'd need RAM to go with it since the massive majority of people do not have DDR3L RAM, so you'd want DDR4 RAM and then you'll have spent the same or more for Skylake as X99. That's stupid. People still don't think X99 is valuable for its 5820K being $40 less at microcenter with even more performance than this quad core. On my article "Are X99 Chipsets Worth Buying" here on GD the overwhelming majority stated they would get Skylake but don't know prices

I agree with RedWolf, the only CPU series from Intel that I like since the core "i" series came out are the extreme ones and especially now when you can get an asrock x99 motherboard for 150$, a i7 5820k for 20-30$ more than an i7 4790k and you will have to get ddr4 sooner or later, since in 2016/2017 ddr4 will become mainstream.

Also I remember when people would NOT buy a new GEN of CPUs unless it was 100% better than the previous one, which AMD and Intel achieved with each new GEN at the time.... but nowadays both intel and amd are focusing on the iGPUs, which they should, CPUs are in-efficient compared to GPUs.

DirectX12 is just an API, it doesn't magically improve anything unless the programmer coded the software with this API already available and making use of it,
so no, even when DX12 comes out there will be nothing cool about it imo :)

Actually when DX12 comes out all the better. DX11 can NOT utilize more than 2 cores/threads effectively as Microsoft and AMD have stated, while DX12 can utilize up to 6 cores/threads effectively, plus the is supposed to do most of the or at least a big job of the work instead of the CPU with DX12. And as Tzzsmk said until games and developers don't start utilizing DX12 to it's fullest it's not going to be a big game changer.

Save your money and wait until both AMD and Intel get HSA(or however intel calls it) and developers start to use the iGPUs as secondary CPUs/ co-processors that do all the calculations instead of the CPUs and the CPUs just do instructions and tell their co-processors(iGPUs) what to do.

I was forced to buy a new mobo to upgrade so I wound up getting a 5820K. The hop onto DDR4 and x99 seemed far more economical in the long run than another quad core when I already had a quad core. Is Intel running out of innovations?

an asrock x99 motherboard for 150$, a i7 5820k for 20-30$ more than an i7 4790k and you will have to get ddr4 sooner or later, since in 2016/2017 ddr4 will become mainstream, costs a 100$ more than an z97 build, but still.
Also right now dual cores are mainstream for gaming, well 2 cores/threads for the most demanding games and a couple of cores to handle background apps, since dx11 does NOT benefit and does NOT utilize more than 2 core/threads effectively.
DX12 on the other hand, from what AMD and Microsoft have said and shown will utilize up to 6 cores/threads effectively, so hexa core cpus will become mainstream + a couple of cores for background apps and tasks.

Or if DX12 can make it so that iGPUs in CPUs are used as co-processors, doing all the calculations instead of the CPUs themselves and the CPUs will just do instructions, then nobody will have to worry for in terms of CPU power.
That's why both amd and intel have been focusing on the iGPUs in the past 6 years, instead of CPU performance. But amd and intel, well intel at this point needs to get HSA, or however they call it and make it mainstream.

AMD is not years behind in IPC.
AMD's cores are twice as small per nm/ have twice as less transistors than intel. It's impossible to make them have the same IPC. 2x AMD piledriver cores/ 1x module is actually 30% faster than 1x Ivy-bridge core/thread and 22-25% faster than 1x Haswell core/thread and is the same size per nm and almost the same transistor count.

There is not a real gpu bottleneck of the cpu. Gpu's can be bottlenecked by a cpu inability to process information fast enough for the gpu but the cpu it's self can be used for more then just feeding information to the gpu.
