Grand 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.
For all our results, we show the average frame rate at 1080p first. Mouse over the other graphs underneath to see 99th percentile frame rates and 'Time Under' graphs, as well as results for other resolutions. All of our benchmark results can also be found in our benchmark engine, Bench.

Grand Theft Auto Conclusions
Looking through the data, there seems to be a difference when looking at the results with an AMD GPU and an NVIDIA GPU. With the GTX 1080, there's a mix of AMD and Intel results there, but Intel takes a beating in the Time Under analysis at 1080p. The GTX 1060 is a mix at 1080p, but Intel takes the lead at 4K. When an AMD GPU is paired to the processor, all flags fly Intel.

Hat off to you, Mr Ian. A lot of good and interesting information there.Cheers!

Thanks :) This will hopefully become the new CPU testing standard for us. It's all scripted, making benchmarking relatively easy. Sourcing and writing are now the mentally consuming parts.YukaKun - Monday, July 24, 2017 - link
That is nice to know. Will you write an article about the testing itself? Like detailing the process or something along those lines? It would be interesting to know about those little details, for sure!I'm sure you can glue together an article in no time! *wink wink*

I've had one half-written about the new 2017 suite and an upcoming project for a couple of weeks. Need to get on it! Coffee time...Dr. Swag - Monday, July 24, 2017 - link
Let's hope you won't be Lake to the party...Cellar Door - Monday, July 24, 2017 - link
What is lake to the party is Intel - it is just so firetrucking sad how they refuse to give customers more for their money. HT should be enabled on all their chips, it is there on the physical chip.I will never buy another Intel cpu - what! You got a problem with that Intel?

Ryzen on some r3 cpus don't have SMTLolimaster - Tuesday, July 25, 2017 - link
With the corresponding price, Ryzen 1500X 4c/8t is 90% of the i7 7700 for half the price.Dr. Swag - Tuesday, July 25, 2017 - link
"With the corresponding price, Ryzen 1500X 4c/8t is 90% of the i7 7700 for half the price."This is just incorrect. Ryzen ipc is around 90% of kaby/skylake, but the 7700k oces around 25% higher and also has around a 20% higher out of the box frequency.

Uh oh, now they have to swear to never buy an AMD chip ever ever!
