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

CPU Performance: New Tests!

As part of our ever on-going march towards a better rounded view of the performance of these processors, we have a few new tests for you that we’ve been cooking in the lab. Some of these new benchmarks provide obvious talking points, others are just a bit of fun. Most of them are so new we’ve only run them on a few processors so far. It will be interesting to hear your feedback!

NAMD ApoA1

One frequent request over the years has been for some form of molecular dynamics simulation. Molecular dynamics forms the basis of a lot of computational biology and chemistry when modeling specific molecules, enabling researchers to find low energy configurations or potential active binding sites, especially when looking at larger proteins. We’re using the NAMD software here, or Nanoscale Molecular Dynamics, often cited for its parallel efficiency. Unfortunately the version we’re using is limited to 64 threads on Windows, but we can still use it to analyze our processors. We’re simulating the ApoA1 protein for 10 minutes, and reporting back the ‘nanoseconds per day’ that our processor can simulate. Molecular dynamics is so complex that yes, you can spend a day simply calculating a nanosecond of molecular movement.

Crysis CPU Render

One of the most oft used memes in computer gaming is ‘Can It Run Crysis?’. The original 2007 game, built in the Crytek engine by Crytek, was heralded as a computationally complex title for the hardware at the time and several years after, suggesting that a user needed graphics hardware from the future in order to run it. Fast forward over a decade, and the game runs fairly easily on modern GPUs, but we can also apply the same concept to pure CPU rendering – can the CPU render Crysis? Since 64 core processors entered the market, one can dream. We built a benchmark to see whether the hardware can.

For this test, we’re running Crysis’ own GPU benchmark, but in CPU render mode. This is a 2000 frame test, which we run over a series of resolutions from 800x600 up to 1920x1080.

Dwarf Fortress

Another long standing request for our benchmark suite has been Dwarf Fortress, a popular management/roguelike indie video game, first launched in 2006. Emulating the ASCII interfaces of old, this title is a rather complex beast, which can generate environments subject to millennia of rule, famous faces, peasants, and key historical figures and events. The further you get into the game, depending on the size of the world, the slower it becomes.

DFMark is a benchmark built by vorsgren on the Bay12Forums that gives two different modes built on DFHack: world generation and embark. These tests can be configured, but range anywhere from 3 minutes to several hours. I’ve barely scratched the surface here, but after analyzing the test, we ended up going for three different world generation sizes.

Interestingly Intel's hardware likes Dwarf Fortress.

We also have other benchmarks in the wings, such as AI Benchmark (ETH), LINPACK, and V-Ray, however they still require a bit of tweaking to get working it seems.
