The Intel Core i5-7600K (91W) Review: The More Amenable Mainstream Performer

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.
Here we report the overall time to complete the test – sub-test results can be found in Bench.
The Core i5-7600K does well in the sub-tests that are more IPC dependent, but there are more sub-tests that revolve around threads and frequency and pure single-core grunt. As a result the i5-7600K pretty much matches the i5-6600K for performance.
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.
All the Kaby Lake processors seem to do well in CB15 single threaded performance, given that all the K-processors can reach 4.2 GHz or higher one way or another. This puts the i5-7600K on par with Devil’s Canyon when we factor in the IPC change as well.
Common consensus is that CB15 scales with threads, however the Core i5-7600K sits above the Core i7-2600K thanks to frequency and IPC gains over the years.
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.
Both the HandBrake tests essentially mirror what we saw in CB15 – the Core i5-7600K is there or thereabouts when frequency is the main factor, and when we stick a register-heavy threaded situation in the path, the effect from not having hyperthreading compared to the Core i7-7700K is relatively muted – in this case the i7 is only +20% performance over the i5, despite costing nearly 50% more.
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.
Our Hybrid test is somewhat similar to the HandBrake HQ test, showing the fact that heavy threads reduce the efficacy of hyperthreads.

It's not Zen but it's their own chips of the past years. They even admit that the IPC is unchanged from Sky Lake, so the only way to sell this chip as something new is by jacking up the "official" clock frequency.Bullwinkle J Moose - Tuesday, January 3, 2017 - link
How is preventing anyone from securing their own computer an upgrade?How is limiting what you can do on your computer an upgrade?
It is now legal for the FBI to hack into ANY computer ANYWHERE as long as you are using Windows 7/8 or 10, but I can stop them with XP
So how is this an Upgrade?
Security trumps your definition of "upgrade"

they don't prevent you from using linux, BSD or even your own custom OS and securing your computer.jimbo2779 - Wednesday, January 4, 2017 - link
What does any of this or your other posts have anything to do with the processor reviewed.Can you go post this in a comment section about win vista - 10 so the rest of us aren't subjected to it.
This article is about a cup not Windows.
Thanks.

because Windows XP IS Secure if you know what you're doing!and my Windows software IS compatible with Windows, not Linux

And most software that requires windows XP and is on 10-year old hardware will run just fine under an emulation environment (e.g. wine) on Linux. Or even inside a Windows XP VM running on a linux host OS.Emulation is of course much slower than native, but running an emulator on current generation hardware will still be faster than running native on that 10-year old hardware.
That way you can get a modern operating system with support for modern hardware, without the windows 8/10 spyware, while still being able to run your old winXP apps.
But if you have no desire or need to get a modern OS, if you are happy with XP and the performance that you get on your current hardware, then why the hell are you even asking these questions and looking here? The only reason you'd be looking and asking these questions is if you are interested in upgrading.

you sound confused eldakkawhat exactly is your point of running a secure OS from within a spyware platform with backdoored bitlocker encryption, keylogger, DRM and Windows components you cannot block in your firewall ?
It is TRUE that Windows 10 is the most secure Version of Windows EVER, but Microsoft should finish the sentence.....
Windows 10 is the most secure Version of spyware EVER for the FBI and the NSA, but NOT the End Loser (er...user)
Funny how the Snowden Interview video disapeared from the Internet explaining how he could watch you as you type and edit your text at your computer BEFORE you send the message with your "secure" encrypted messaging app
Those backdoors are there for a reason.....To spy on and hack any "modern" Windows Computer in the World which is why MS had to kill XP and why the Law was changed to allow the FBI to hack ANY computers, anywhere with a single warrant (that went into affect December 1st)
The FBI could not do that if the back doors were closed, but you cannot close them on Windows 10
computers
But the REAL Trolls here won't discuss that now will they?

Because no one cares about your AWESOME Windows XP! Get of the Internets everyone!!!! OMG, Spy FBI CIA NSA HELPS ME!!!Really dude, you are awesome. Thanks for repeating the same crap over and over again and showing your real ignorance. If you really knew what you were doing, you wouldn't have to explain yourself.

And if you have SUPER SECRETS that you don't want anyone to know about, guess what?Don't go online? You do realize that just having any port open allows someone to see your packets. You really think your ISP is secure? Because once a packet leaves your house, it's not your network anymore.
If any of the mentioned entities really want information from you, they'll just come in and physically take it.

The most secure operating system is one which allows for no input and gives no output. At that point, it's not a computer.
