The Skylake Core i3 (51W) CPU Review: i3-6320, i3-6300 and i3-6100 Tested

All of our benchmark results can also be found in our benchmark engine, Bench.
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.
The different stages of Photoscan have different preferences for frequency and threads, but all the results are in Bench. In this case having threads matters, with the old 8-thread FX CPU barely getting ahead of the Core i3 parts. The i5 takes the lead, showing that having physical cores helps with cache management. This is further reinforced by our results staircase, which put the i3-6320 and i3-6300 at roughly equal timings but the i3-6100 almost 4% behind.
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.
Cinebench eats threads, high IPC and high frequency for breakfast. In the single thread test, the high Intel IPC shines through, and our i3 parts sit in unison with AMD behind by up to 40%. In multithreaded land, the 6/8 thread FX processors go ahead of the i3s as expected, and our staircase slightly deviates for the i3-6100 showing that L3 cache creep is slowly coming in.
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.
The high IPC of the Skylake parts makes a difference for the smaller frame conversion, while threads come into play for the larger resolution frames. In both cases, the regular staircase shows a lack of issues with the L3 cache differences, but it is interesting to see the X4 845 hot on the heels for the high resolution frames despite its cache arrangement. The FX-6350 sits on par with the i3-6100, showcasing the difference between a six-thread much older processor and a four thread latest process part.
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.
Hybrid is similar to HandBrake, and we again have a regular staircase.

I remember in Eurogamer's i3-6100 review, just using 2666 or 3200MHz DDR4 gave a significant performance boost in pretty much all games, especially Ryse whose maximum FPS almost doubled from 59 to over 100FPS. And this was at the stock CPU clockspeed. Minimum frames improved substantially too.wintermute000 - Monday, August 8, 2016 - link
Problem is the price premium for 3200Mhz, you're already halfway to the cost of a dGPU like a GTX950 or R460 that will blow the doors off any iGPUwintermute000 - Monday, August 8, 2016 - link
whoops I guess I was looking at the expensive stuff, realised that not all 3200 is priced that much higherbeginner99 - Tuesday, August 9, 2016 - link
exactly. If you go Skylake, buy 3200 mhz RAM. For 16 GB it's only $20-30 more than 2133 mhz RAM and totally worth it.fanofanand - Monday, August 8, 2016 - link
Fantastic article Ian, you are definitely doing a great job of filling in the "lull" period between major GPU reviews. I have been wanting exactly this review to be done, as I would love to be able to build my kid a cheap computer for school that could do a bit of light gaming. I was really hoping the APUs would give adequate performance, but it looks like I will be waiting for Zen. I really don't want to get a dGPU for his computer and with Intel it doesn't look like there is much of a choice. Zen it is! Please don't disappoint us AMD!BrokenCrayons - Tuesday, August 9, 2016 - link
I'm keenly interested in seeing what Zen brings to the table too. However my next desktop PC upgrade is going to be a GPU of some sort and even that's probably a good 6+ months away if not more. Zen will be another CPU+Mobo+RAM swap and I'm not looking forward to anything of the sort right now...unless Zen can more than double the performance of my 860K, at which point I'll be very interested.Achaios - Monday, August 8, 2016 - link
Bought a brand new laptop today with an Intel Core i5-6200U Skylake onboard (which you have failed to include in your table) clocked at 2.3 GHz which turbos to 2.8 GHz.The thing I wanna say if you try to install Windows 7 on a Skylake machine without making a little in-depth research, you're screwed.
One way to install Windows 7 on Skylake machines is described by the following ASROCK article:
http://www.asrock.com/microsite/win7install/
(Thank you ASROCK).
I am not ashamed to say I spent the better part of day fighting off the dreaded "A required CD/DVD drive device driver is missing" before I had my Windows 7 Pro 64 Bit slipstreamed and updated by ASROCK's app.
Perhaps you should consider adding a couple of words on the subject as there are many ppl who will stay on Windows 7 for several years to come and are not very familiar with the Skylake platform.

Well, of course it's not on the table - that's a mobile chip. Plus unless you have some specific business need to use Windows 7 I don't see why you would go through the hassle of putting it on there. It's an almost 7 year old OS.fanofanand - Tuesday, August 9, 2016 - link
LOL "failed to include" I love it. "I bought it so you should review it, even if it's not even in the same segment as the other products you are reviewing". Classic snowflake narcissism.Meteor2 - Tuesday, August 9, 2016 - link
1. I wish you'd calculated price/performance and power/performance for us, rather than leaving us to guesstimate2. The game benchmarks need 95th (or whatever) percentile frame rates and minimum frame times, as that's where the performance difference between i3 and i5 truly lies.
