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.

Or fix the cpu scheduler to properly schedule threads for the highest trough put/latency/power efficiency depending on what the thread/program is doing (compressing a lot of data for archival doesn't need low latency, games/multimedia/UIs/... need low latency) the state of the machine (if you are connected to the power grid and not over heating power efficiency is not as important if you are on battery power in the middle of nowhere or if it's summer and you have no ac), user preferences (I might still be cheap and want lower total power consumption even if it means slightly less performance for things that are running in the background, or I could be using electric heating so power efficiency doesn't matter since the heat isn't waste, or maybe I want that things being run by me run better then the things that my friend is running over the network (I mean I would rather have my ui and videos smooth than his).bji - Tuesday, May 31, 2016 - link
One thing I never understand: what does "uncore" mean? It sounds like it's all the stuff that's not part of the cores. And yet, we have "Queue" and "I/O" listed separately. Why aren't those things "uncore"?keeepcool - Tuesday, May 31, 2016 - link
Wikipedia knows what it is:https://en.wikipedia.org/wiki/Uncore
:)
Also the Sparc is also somewhere burried in that mess.

OK thanks for the pointer. So Uncore is Intel's way of referring to specific parts of the CPU that interface directly with the cores and have to be very high performance, mostly managing inter-core communication functions like cache coherency and memory access, and some high performance interconnect stuff like Thunderbolt. Not sure why they bother to have a specific name for these sections, instead of calling them out directly when they are interesting, but whatever.Morawka - Tuesday, May 31, 2016 - link
Wow price increases across the board. Even the 8core got a $100 increase almost. Lame.6950x was supposed to be $999, and the 8 core $600, but i see Intel doesnt have any competition so everyone has to pay.
I'd wait for skylake E this fall/winter

Newegg sells all xeons. Even the 20 core versions. No need to ask a system builder to order one for youmooninite - Tuesday, May 31, 2016 - link
O RLY? Find me a E3-1260L v5 on Newegg.James S - Tuesday, May 31, 2016 - link
I give you newegg doesn't sell every single CPU made but they do have the Xeon E3-1270 v5, they don't have the low power variants as you already know. One could simply snag one off Dell.com though.legolasyiu - Tuesday, May 31, 2016 - link
You should be able to overclock much better using Strix X99 gaming or Rampage V Extreme / Edition 10. I was clocking 4.3Ghz without issues with 6800K and will push 4.4Ghz soonezcameron76 - Tuesday, May 31, 2016 - link
So I just bought the 6800k instead of the 5820k. After reading this I feel like I made the bad call and could have saved some money and get the Haswell E. Thoughts on this as I dont want to make a mistake and the new one has just shipped. I mainly play games but do some creation as well. I am redoing my pc and dont want to make a bad call if the 6800k can't overclock more then the haswell 5820k. Thoughts please everyone share.
