The Intel Core i3-7350K (60W) Review: Almost a Core i7-2600K

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.
Photoscan is a mix of single and multi-threaded segments, but overall the extra cores in the i5/i7 beat the Core i3, but not by much.
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. Nonetheless, the age of the Core i7-2600K is showing here.
Turning the tables with actual cores, and the Core i7-2600K gets a significant leg up here. The Core i5 also sits above the Core i3.
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.
For video conversion, having small frames puts all three CPUs in a similar spot. But ramp up the frame size and we see the Kaby Lake i5 pull ahead due to IPC and instructions. The Core i3 has enough oomph to match the extra threads on the Core i7-2600K though.
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.
With a different video conversion tool and render, the extra cores and threads of the Core i7 is more than enough to give it a 30% advantage over the Core i3-7350K. It makes me wonder if another +30% frequency would help the Core i3.

"celeron - duel core"Calm down, breathe. It's not something worth dueling over!

Yeah eldakke, "duel" vs "dual" is also something that gets my heart rate up. :-)Old_Fogie_Late_Bloomer - Monday, February 6, 2017 - link

Duel core? Funny mine never got into a fight.....R0H1T - Friday, February 3, 2017 - link
Yeah that's true except when people find out that there's this thing called Ryzen just on the horizon. Seems to me that the HT pentium & unlocked is just a way to sell more of these KL chips & Intel are hoping/waiting for Coffee Lake to counter Zen.There's no way a dual core is justified today, even if unlocked or with HT, unless you're absolutely on a shoestring of a budget &/or KL is the only thing you want. It's such bad value for money atm that no one should be recommending it, not at this point in time.

I have to agree. Not necessarily because there is anything wrong with this chip technically but because of the competitive landscape where Intel's own quad-core chips can be had for the same or lower prices.Meteor2 - Sunday, February 5, 2017 - link
I think the only thing which can be recommended at the moment is not to buy a CPU until Zen is released, in case AMD live up to their hype in performance and price their products competitively (I.e. cheaper than Intel).bananaforscale - Wednesday, February 8, 2017 - link
And see how Intel reacts. Gimme a 20% price drop on hex cores!Jumangi - Saturday, February 4, 2017 - link
They would be misleading gamers badly as is this Anandtech review. Their gaming becnhmarks are just woefully out of date its getting embarassing. There are already games that have come out like Farcry 4 that literally won't run if the system doesn't have 4 full cores. Any real gamer is screwing themselves over by trying to skimp on a CPU like this. Any legit tech site would never reccomend less than a 4 core CPU in 2017.Meteor2 - Sunday, February 5, 2017 - link
@nathanandrews hasn't that always been the case? Except, you might not be able to afford an i7, and (as these results show) you're better buying an i5 and a better GPU for gaming.
