The AMD Ryzen 3 3300X and 3100 CPU Review: A Budget Gaming Bonanza

Our System Test section focuses significantly on real-world testing, user experience, with a slight nod to throughput. In this section we cover application loading time, image processing, simple scientific physics, emulation, neural simulation, optimized compute, and 3D model development, with a combination of readily available and custom software. For some of these tests, the bigger suites such as PCMark do cover them (we publish those values in our office section), although multiple perspectives is always beneficial. In all our tests we will explain in-depth what is being tested, and how we are testing.
All of our benchmark results can also be found in our benchmark engine, Bench.
Application Load: GIMP 2.10.4
One of the most important aspects about user experience and workflow is how fast does a system respond. A good test of this is to see how long it takes for an application to load. Most applications these days, when on an SSD, load fairly instantly, however some office tools require asset pre-loading before being available. Most operating systems employ caching as well, so when certain software is loaded repeatedly (web browser, office tools), then can be initialized much quicker.
In our last suite, we tested how long it took to load a large PDF in Adobe Acrobat. Unfortunately this test was a nightmare to program for, and didn’t transfer over to Win10 RS3 easily. In the meantime we discovered an application that can automate this test, and we put it up against GIMP, a popular free open-source online photo editing tool, and the major alternative to Adobe Photoshop. We set it to load a large 50MB design template, and perform the load 10 times with 10 seconds in-between each. Due to caching, the first 3-5 results are often slower than the rest, and time to cache can be inconsistent, we take the average of the last five results to show CPU processing on cached loading.
3D Particle Movement v2.1: Brownian Motion
Our 3DPM test is a custom built benchmark designed to simulate six different particle movement algorithms of points in a 3D space. The algorithms were developed as part of my PhD., and while ultimately perform best on a GPU, provide a good idea on how instruction streams are interpreted by different microarchitectures.
A key part of the algorithms is the random number generation – we use relatively fast generation which ends up implementing dependency chains in the code. The upgrade over the naïve first version of this code solved for false sharing in the caches, a major bottleneck. We are also looking at AVX2 and AVX512 versions of this benchmark for future reviews.
For this test, we run a stock particle set over the six algorithms for 20 seconds apiece, with 10 second pauses, and report the total rate of particle movement, in millions of operations (movements) per second. We have a non-AVX version and an AVX version, with the latter implementing AVX512 and AVX2 where possible.
3DPM v2.1 can be downloaded from our server: 3DPMv2.1.rar (13.0 MB)
Dolphin 5.0: Console Emulation
One of the popular requested tests in our suite is to do with console emulation. Being able to pick up a game from an older system and run it as expected depends on the overhead of the emulator: it takes a significantly more powerful x86 system to be able to accurately emulate an older non-x86 console, especially if code for that console was made to abuse certain physical bugs in the hardware.
For our test, we use the popular Dolphin emulation software, and run a compute project through it to determine how close to a standard console system our processors can emulate. In this test, a Nintendo Wii would take around 1050 seconds.
The latest version of Dolphin can be downloaded from https://dolphin-emu.org/
DigiCortex 1.20: Sea Slug Brain Simulation
This benchmark was originally designed for simulation and visualization of neuron and synapse activity, as is commonly found 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, equivalent to a Sea Slug.
Example of a 2.1B neuron simulation
We report the results as the ability to simulate the data as a fraction of real-time, so anything above a ‘one’ is suitable for real-time work. Out of the two modes, a ‘non-firing’ mode which is DRAM heavy and a ‘firing’ mode which has CPU work, we choose the latter. Despite this, the benchmark is still affected by DRAM speed a fair amount.

y-Cruncher v0.7.6: Microarchitecture Optimized Compute
I’ve known about y-Cruncher for a while, as a tool to help compute various mathematical constants, but it wasn’t until I began talking with its developer, Alex Yee, a researcher from NWU and now software optimization developer, that I realized that he has optimized the software like crazy to get the best performance. Naturally, any simulation that can take 20+ days can benefit from a 1% performance increase! Alex started y-cruncher as a high-school project, but it is now at a state where Alex is keeping it up to date to take advantage of the latest instruction sets before they are even made available in hardware.
For our test we run y-cruncher v0.7.6 through all the different optimized variants of the binary, single threaded and multi-threaded, including the AVX-512 optimized binaries. The test is to calculate 250m digits of Pi, and we use the single threaded and multi-threaded versions of this test.
Users can download y-cruncher from Alex’s website: http://www.numberworld.org/y-cruncher/
Agisoft Photoscan 1.3.3: 2D Image to 3D Model Conversion
One of the ISVs that we have worked with for a number of years is Agisoft, who develop software called PhotoScan that transforms a number of 2D images into a 3D model. This is an important tool in model development and archiving, and relies on a number of single threaded and multi-threaded algorithms to go from one side of the computation to the other.
In our test, we take v1.3.3 of the software with a good sized data set of 84 x 18 megapixel photos and push it through a reasonably fast variant of the algorithms, but is still more stringent than our 2017 test. We report the total time to complete the process.

4790K 6700K 7700KAll Intel quad core showing generational differences as to where the 3300X and 3100 fit in.
1600X, 1700, 1700X, 1800X are all in our benchmark database, Bench.
It's practically listed on almost every page.

And that's obviously great. But with that approach you could just write "3100 and 3300X added to Bench", right? :)I have nothing against the factual layer of this article. Results are as expected and they look consistent.
But it's essentially a story how an entry-level $120 CPU from company A beats a not-so-ancient flagship from company B.
So I'm merely wondering why you decided to write it like this, instead of comparing to wider choice of expensive CPUs from 2017. Because in many of your results 3300X beats 1st gen Ryzens that were even more expensive than the 7700K.
Or you could include older 4C/8T Ryzens (1500X) - showing how much faster Zen2 is.
Instead you've included the older 6-core Ryzens, which are neither similar in core count nor in MSRP.

2600/1600 AF is ~$85 at retail (where you can find it), and judging by the comments, VERY popular. That's why this was included.Deicidium369 - Friday, May 8, 2020 - link
Just say AMD GOOD! INTEL BAD! that's all they are looking foreastcoast_pete - Thursday, May 7, 2020 - link
Some other sites have, and yes, the 3300 gives most of the 1st generation Ryzens a run for their money.Irata - Thursday, May 7, 2020 - link
This is a highly impressive little CPU for the money.I particularly liked the 3300X‘s good showing. If this is at least in part due to it using only one CCX, this should bode well for Ryzen 3 which should have an eight core CCX.
Look at some tests were Ryzen did not do so well wrt their Intel counterpart like Kraken and Octane - the 3300x now does very well. It even scores slightly better than the 3700x

Does the B550 MB need active cooling? I can't tell from the pic.callmebob - Thursday, May 7, 2020 - link
Look at the spec graphics. Note the only difference to the old B450 is pretty much that it provides PCIe 3.0 lanes instead of PCIe 2.0.Now, when was the last time you saw a PCIe 3.0-based chipset hub needing active cooling?
As an aside, while i am kinda glad the B550 is finally coming, i am also a bit disappointed in seeing AMD (and their design/manufacturing partners) needing a better part of a year just for managing a bump from PCIe 2.0 to PCIe 3.0. PCIe 3.0 has been in the market for around eight years now; there is no excuse for AMD taking this long to figure out this s*it.
Fritzkier - Thursday, May 7, 2020 - link
Because their PCIe 3 and 4 was provided by the CPU tho. Or maybe there's an advantage of PCIe lanes provided by the chipset?callmebob - Thursday, May 7, 2020 - link
Haha, do you even know _how many_ PCIe lanes the CPU provides? Wager a guess whether it is for more than a single x16 slot?
