The AMD Ryzen Threadripper 1950X and 1920X Review: CPUs on Steroids
by Ian Cutress on August 10, 2017 9:00 AM ESTGrand Theft Auto
The highly anticipated iteration of the Grand Theft Auto franchise hit the shelves on April 14th 2015, with both AMD and NVIDIA in tow to help optimize the title. GTA doesn’t provide graphical presets, but opens up the options to users and extends the boundaries by pushing even the hardest systems to the limit using Rockstar’s Advanced Game Engine under DirectX 11. Whether the user is flying high in the mountains with long draw distances or dealing with assorted trash in the city, when cranked up to maximum it creates stunning visuals but hard work for both the CPU and the GPU.
For our test we have scripted a version of the in-game benchmark. The in-game benchmark consists of five scenarios: four short panning shots with varying lighting and weather effects, and a fifth action sequence that lasts around 90 seconds. We use only the final part of the benchmark, which combines a flight scene in a jet followed by an inner city drive-by through several intersections followed by ramming a tanker that explodes, causing other cars to explode as well. This is a mix of distance rendering followed by a detailed near-rendering action sequence, and the title thankfully spits out frame time data.
There are no presets for the graphics options on GTA, allowing the user to adjust options such as population density and distance scaling on sliders, but others such as texture/shadow/shader/water quality from Low to Very High. Other options include MSAA, soft shadows, post effects, shadow resolution and extended draw distance options. There is a handy option at the top which shows how much video memory the options are expected to consume, with obvious repercussions if a user requests more video memory than is present on the card (although there’s no obvious indication if you have a low-end GPU with lots of GPU memory, like an R7 240 4GB).
To that end, we run the benchmark at 1920x1080 using an average of Very High on the settings, and also at 4K using High on most of them. We take the average results of four runs, reporting frame rate averages, 99th percentiles, and our time under analysis.
All of our benchmark results can also be found in our benchmark engine, Bench.

Depending on the CPU, for the most part Threadripper performs near to Ryzen or just below it.

Why did you end all the gaming review sections with something like "Switching it to Game mode would have made better numbers..."? Why didn't you run the benchmarks in Gaming mode in the first place?Ian Cutress - Thursday, August 10, 2017 - link
Gaming mode is not default, and we run gaming mode alongside the default - there's two sets of values in each graming test.DanNeely - Thursday, August 10, 2017 - link
You might want to call that out more clearly in the text. I also missed that you have two sets of 1950X results; and probably wouldn't've figured out what the -G suffix meant without a hint.Ian Cutress - Thursday, August 10, 2017 - link
I mentioned it in the Game vs Creator mode page, but I'll propagate it through.lordken - Thursday, August 10, 2017 - link
read before you complain, it is stated at beginning of the review that -G is for game mode...DanNeely - Thursday, August 10, 2017 - link
Especially during the work day a lot of people just are doing quick glances at the most interesting parts. I'll end to end read it sometime tonight.mapesdhs - Thursday, August 10, 2017 - link
If people quick-glance, that's their problem for missing key info. :D When learning about something as new as this, I read everything. Otherwise, it's like the tech equivalent of crossing a road while gawping at a phone. :}Last time I read so much about a new CPU launch was Nehalem/X58.

It seemed really clear to me but for people who didn't read the long text on NUMA etc maybe not.The dangers of skimming!

Indeed. :D Reminds me of when a long time ebay seller told me that long item decriptions are pointless, because most bidders only read the first paragraph, often only the first sentence.Ian Cutress - Thursday, August 10, 2017 - link
The test suite is a global glove: rather than have 20 tests for each segment, it's a global band of 80 tests for every situation. Johan does different tests as his office is several hundred miles away from where I am (and we're thousands of miles away from any other reviewer).For the gaming benchmarks, there are big differences in 99th percentile frame rates and Time Under analysis. As games become more and more GPU bottlenecked for average frame rates, this is where the differentiation point is. It's a reason why we still test 1080p as well. With regards the AI test, I've asked the Civ team repeatedly to make the AI test accessible from the command line so I can rope it into my testing scripts easily (they already do it with the main GPU test). But like many other game studios, getting them to unlock a flag is a frustrating endeavor when they don't even respond to messages.
