The Intel 6th Gen Skylake Review: Core i7-6700K and i5-6600K Tested

Agisoft Photoscan – 2D to 3D Image Manipulation: link
Agisoft Photoscan creates 3D models from 2D images, a process which is very computationally expensive. The algorithm is split into four distinct phases, and different phases of the model reconstruction require either fast memory, fast IPC, more cores, or even OpenCL compute devices to hand. Agisoft supplied us with a special version of the software to script the process, where we take 50 images of a stately home and convert it into a medium quality model. This benchmark typically takes around 15-20 minutes on a high end PC on the CPU alone, with GPUs reducing the time.
Cinebench R15
Cinebench is a benchmark based around Cinema 4D, and is fairly well known among enthusiasts for stressing the CPU for a provided workload. Results are given as a score, where higher is better.
HandBrake v0.9.9: link
For HandBrake, we take two videos (a 2h20 640x266 DVD rip and a 10min double UHD 3840x4320 animation short) and convert them to x264 format in an MP4 container. Results are given in terms of the frames per second processed, and HandBrake uses as many threads as possible.
Hybrid x265
Hybrid is a new benchmark, where we take a 4K 1500 frame video and convert it into an x265 format without audio. Results are given in frames per second.

I still don't see the point in upgrading from Sandybridge let alone anything newer. Its a big chunk of a cash for a new mobo, CPU and memory, all for what, 25%?Cumulus7 - Wednesday, August 5, 2015 - link
Exactly.Usually i suggest an upgrade if you get approximately twice the performance (+100%). But for 25%: forget it! Never!!!

The other way of looking at it is that it's amazing how good the Sandy Bridge numbers hold up, that good ol' 2600k is one of Intel's all-time great CPUs. Be happy you backed a winner!mrcaffeinex - Wednesday, August 5, 2015 - link
I did and I am very happy. It frees up funds to focus on other parts that make a bigger impact like more RAM, a larger SSD, and of course a better video card.This is better than Haswell in several ways and I imagine the overclockers are going to have some fun since they have been given back more options than some of the previous generations. At least it looks like Intel is paying more attention to the enthusiasts this time around, even if they are not the largest target market.

Well, I'm glad I held back on the 2600K and 3770K and got haswell!! - So with this kind of reasoning, its a never ending circle.Look at the platform overall, the pcix storage, nvme compatibility, m.2 ports. USB 3.1 which will be all over the place a lot faster then people realize.
At the same speed its 37% faster and "In specific tests, it is even higher" - a good clocking 6700K will be a nice upgrade for anyone with Sandy. Just like Haswell was for Nahelem users.
Seems a perfectly justifiable upgrade.

Eh. I've been wanting an excuse to upgrade from my 2600k. I am an "enthusiast" and building PC's and such is my hobby. So, it's not always just simply the price/perf value proposition. Christmas is coming up and my nephew doesn't have his own PC yet, and also loves to play steam games (he usually does it at his grandparents). So, this gives me an excuse to build a new setup. I still have my GTX 760 laying around that i upgraded to a 980ti. So a 6700k setup would be a nice pairing with the 980ti and should realistically set me for 3-4 years.kmmatney - Wednesday, August 5, 2015 - link
I'm an i5 3570K owner. If I'm going to upgrade, I'd look for an i7-4790K (or even a i7 2600K) on Ebay before completely overhauling my system with this.darkfalz - Wednesday, August 5, 2015 - link
Even that's a waste of money unless you are doing a tonne of Handbrake.mapesdhs - Wednesday, August 12, 2015 - link
No, get a 2700K instead, they oc much better than the 2600K.2700K = 5GHz guaranteed, even with a simple TRUE and one fan (I use the ASUS M4E,
built five so far).

Agreed. Especially when you factor in that those 25% is peak performance. How often does the average user call on peak performance? I think the most common and frequent scenario for average users to need CPU power is gaming. And here, due to the fact that GPUs are the bottleneck, you won't even get 10%.From an enthusiast point of view, the last 4 years since Sandy Bridge have been disappointing. If not outright worrying.
