Grand Theft Auto V
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.

I'm not sure. :D It's certainly annoying though. Worst part is searching for anything and then changing the list order to cheapest first, what a mess...SunnyNW - Thursday, October 5, 2017 - link
"That changes today."Anyone else read that and think that it is something we should have been reading ages ago?
Consumer technology is progressing slower than many expected and I feel the same way. Nonetheless I can't help but envision a Very near future where I'll be coming back and reading this article and being depressed at this level of technology all the while on my future monolithic many thousand core 3D processor ;)

Yes. A year ago this would have been an exciting development. Now it's just Intel remaining competitive against AMD's offerings.Valcoma - Thursday, October 5, 2017 - link
"The Core i5-8400 ($182) and Core i3-8350K ($169) sit near the Ryzen 5 1500X ($189) and the Ryzen 5 1400 ($169) respectively. Both the AMD parts are six cores and twelve threads, up against the 6C/6T Core i5 and the 4C/4T Core i3. The difference between the Ryzen 4 1400 and the Core i3-8350K would be interesting, given the extreme thread deficit between the two."Those AMD parts are 4 cores, 8 threads.

You're right, had a brain spasm while writing that bit. Updated.kpb321 - Thursday, October 5, 2017 - link
Still off"The difference between the Ryzen 5 1500X and the Core i3-8350K would be interesting, given the extreme thread deficit (12 threads vs 4) between the two."
the 1500X is a 4c8t processor so it effectively has hyper-threading over the i3-8350K while having a lower overclocking ceiling and lower ipc.

Ian, I love the way the gaming benchmarks are listed. So easy to access and much less confusing than drop-downs or arrows. Nice job!Valcoma - Thursday, October 5, 2017 - link
Are you sure that the i5-7400 got 131 FPS average in benchmark 1 - Spine of the Mountain in Rise of the Tomb Raider? Besting all the other vastly superior processors?Looks like a typing error there or something went wrong with your benchmark (lower settings for example on that run).

I've mentioned it in several reviews in the past: RoTR stage 1 is heavily optimized for quad core. Check our Bench results - the top eight CPUs are all 4C/4T. The minute you add threads, the results plummet.https://www.anandtech.com/bench/CPU/1827
