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.

7350K seems like a good old overcloking fun CPU. Introduced just ahead of Ryzen launch. Taking this one from 4.2 to 5GHz is a good +20% overclock. And good (not incredible) value at $175. This or its successor on 10nm will be my next gaming machine.skpetic - Wednesday, January 4, 2017 - link
1. Aggregated results are that an i7-6700 is as fast as the i5-7600K(?)2. The 6700 is more future proof as it has better performance in applications with good multithreading implementations (future apps and games)
3. Why is this not considered in the review?

Had I known this in 2011 when I bought i5-2500k I would have purchased i7-2600k for hyperthreading as it helps in spice simulations. I also would have spend 100$ more to better modo. On the other hand I saved 200$+interest not doing so...I'm almost happy that advancement in performance has slowed down. No need to upgrade and finally we are seeing software being optimized. Like Chrome browser, we wouldn't see these java script competitions if never hardware would be suffice.

In the 5th paragraph you have the 7600K as 4.0 base/ 4.2 turbo but in the table it is listed as 3.8 base/ 4.2 turbopavag - Wednesday, January 4, 2017 - link
I cannot find the log out linkzodiacfml - Thursday, January 5, 2017 - link

Why is the ivy bridge you are using the 3770k, an i7, instead of an i5 3570k? Don't you think people considering the i5 are more likely to have ... AN IFIVE@!!!!Adam Saint - Saturday, January 7, 2017 - link
Looks like the 4790k is holding up exceptionally well in both single and multithreaded tests. Impressive for a chip that's 3 generations old.epobirs - Sunday, January 15, 2017 - link
I build new systems as a hobby, so I'm not especially concerned with whether the new box is a sufficient upgrade over my current main system. That my next build can have some incremental improvements at about the same price point is real progress in my book. Right now, I have a pair of Antec mITX cases I got especially cheap. The original purpose they were intended to serve has been cancelled, so some HTPC configurations are likely, just for the fun of it. since some of Kaby Lakes upgrades are directly applicable to an HTPC's needs, those are likely the parts I'll use if no Skylake items become available for an especially good price.In general, incremental upgrades of the product line don't offend me any more than minor improvements to an automobile model from one year to the next. Just because I'm not in the market for a new car this year doesn't mean they should hold still. There are plenty of others who are more than due for an upgrade and those incremental improvements add up eventually for everybody.

It is good that we know so much of the gta. http://mygtacheats.com
