The AMD Ryzen 5 1600X vs Core i5 Review: Twelve Threads vs Four at $250

Our first set of tests is our general system tests. These set of tests are meant to emulate more about what people usually do on a system, like opening large files or processing small stacks of data. This is a bit different to our office testing, which uses more industry standard benchmarks, and a few of the benchmarks here are relatively new and different.
PDF Opening
First up is a self-penned test using a monstrous PDF we once received in advance of attending an event. While the PDF was only a single page, it had so many high-quality layers embedded it was taking north of 15 seconds to open and to gain control on the mid-range notebook I was using at the time. This put it as a great candidate for our 'let's open an obnoxious PDF' test. Here we use Adobe Reader DC, and disable all the update functionality within. The benchmark sets the screen to 1080p, opens the PDF to in fit-to-screen mode, and measures the time from sending the command to open the PDF until it is fully displayed and the user can take control of the software again. The test is repeated ten times, and the average time taken. Results are in milliseconds.
Opening PDFs using Adobe is significantly single threaded, hence why Intel takes the win here for the most part - the 7400 is slightly lower on frequency, enough for the 4.0 GHz Ryzen parts to push ahead.
FCAT Processing
One of the more interesting workloads that has crossed our desks in recent quarters is FCAT - the tool we use to measure stuttering in gaming due to dropped or runt frames. The FCAT process requires enabling a color-based overlay onto a game, recording the gameplay, and then parsing the video file through the analysis software. The software is mostly single-threaded, however because the video is basically in a raw format, the file size is large and requires moving a lot of data around. For our test, we take a 90-second clip of the Rise of the Tomb Raider benchmark running on a GTX 980 Ti at 1440p, which comes in around 21 GB, and measure the time it takes to process through the visual analysis tool.
Similarly, FCAT is single threaded as it analyzes frame-by-frame. The extra frequency helps Intel here.
3D Particle Movement v2.1
This is the latest version of the self-penned 3DPM benchmark. The goal of 3DPM is to simulate semi-optimized scientific algorithms taken directly from my doctorate thesis. Version 2.1 improves over 2.0 by passing the main particle structs by reference rather than by value, and decreasing the amount of double->float->double recasts the compiler was adding in. It affords a ~25% speed-up over v2.0, which means new data.
DigiCortex 1.20
Despite being a couple of years old, the DigiCortex software is a pet project for the visualization of neuron and synapse activity in the brain. The software comes with a variety of benchmark modes, and we take the small benchmark which runs a 32k neuron/1.8B synapse simulation. The results on the output are given as a fraction of whether the system can simulate in real-time, so anything above a value of one is suitable for real-time work. The benchmark offers a 'no firing synapse' mode, which in essence detects DRAM and bus speed, however we take the firing mode which adds CPU work with every firing.
Agisoft Photoscan 1.0
Photoscan stays in our benchmark suite from the previous version, however now we are running on Windows 10 so features such as Speed Shift on the latest processors come into play. The concept of Photoscan is translating many 2D images into a 3D model - so the more detailed the images, and the more you have, the better the model. The algorithm has four stages, some single threaded and some multi-threaded, along with some cache/memory dependency in there as well. For some of the more variable threaded workload, features such as Speed Shift and XFR will be able to take advantage of CPU stalls or downtime, giving sizeable speedups on newer microarchitectures.
Because parts of Photoscan are very multithreaded, such as the first stage, there's plenty of scope for the Ryzen CPUs to pull ahead here.

I agree - this is implying the reverse of what was probably meant. And it's still broken.coder543 - Tuesday, April 11, 2017 - link
"For $250, the top Ryzen 5 1600X gives six cores and twelve threads of AMD’s latest microarchitecture, while $250 will only get you four cores and no extra threads for the same price."You're missing a word in here. That word is "Intel". Right now, the opening paragraph contains one of the most confusing sentences ever written, because the only brand mentioned is AMD, where $250 simultaneously gets you 6 cores and 12 threads *and* only 4 cores? Please update this paragraph to show that Intel only gets you 4 cores.

I agree - you really need to add "with Intel". This is a theme statement for the entire article and worth fixing.CaedenV - Tuesday, April 11, 2017 - link
Well, that review was surprising.I am looking to re-do my system in the next year or so, and I thought for sure that the R5 would be the no-brainer pick. But that seems not to be the case. If on a tight budget it looks like the i3 is the all-around value king offering great single-thread performance and decent light to moderate gaming. The i5 still reigns king for non-production work while being right about the same price point as the R5. And if doing production work the R7 really makes more sense as it is not that much more expensive while offering much better render performance. I somehow thought that the R5 would be better priced against the i5, just as the R7 stomps all over the i7 chips.
So now when I look at building my next PC the real question is how much production work I plan on doing. If it is a lot then the R7 is the way to go. But if I am just doing media consumption and gaming then perhaps the Intel i5 will still be the best option. Hmm... maybe I'll just wait a bit longer. I mean, my i7 2600 still keeps chugging along and keeping up. The real temptation to upgrade is DDR4, USB-C, m.2, and PCIe v3. Seeing more 10gig Ethernet would also be a big temptation for an upgrade, but I think we are still 2-3 years out on that. Any up-tick in raw CPU performance is really a secondary consideration these days.

That is a strange position indeed, as it conflicts with all the data in the review.In other words lol wut?
Meteor2 - Wednesday, April 12, 2017 - link
Indeed. My conclusion was 'wow, AMD have knocked it out of the park'. Same or better gaming, far better production.Cooe - Monday, March 1, 2021 - link
What happened to your "Ryzen 5 will be shit" comments from all over the OG Ryzen 7 review???Drumsticks - Tuesday, April 11, 2017 - link
It's not really hard to figure out. If you just do media and gaming, stick with Intel.If you rely on your home PC for any significant measure of production work, you should probably be buying the most expensive Ryzen chip you can.

Yeah, for the longest time I've maintained separate rigs for gaming and video work, but I'm in the process of building a hybrid machine and the Ryzen 7 chips came out at just the right time. I just ordered an 1800X for my new workstation/gaming/VR rig. Gaming performance is somewhat important to me, but I can handle lower frame rates in certain games versus the 7700K because for my post-production video work, I need those extra cores and threads. For the longest time Intel was able to charge whatever they wanted at the high-end and prices had gotten ridiculous, so the 7-series fills a huge niche.However, it seems less clear where the Ryzen 3 and 5 chips will fit in. People who only use their machines for games won't see very many of the benefits of the Zen architecture, but they're saddled with the weaknesses of relatively slower single-threaded performance, and AMD isn't competing on price.

You did luck out. u r the perfect ryzen demographic.I suspect teamed with a vega 8GB hbm & a pcie ssd, it will blow you away by xmas.
But the 1600 6 core comes close mostly, for $250~ less.
