Civilization 6
First up in our CPU gaming tests is Civilization 6. Originally penned by Sid Meier and his team, the Civ series of turn-based strategy games are a cult classic, and many an excuse for an all-nighter trying to get Gandhi to declare war on you due to an integer overflow. Truth be told I never actually played the first version, but every edition from the second to the sixth, including the fourth as voiced by the late Leonard Nimoy, it a game that is easy to pick up, but hard to master.
Benchmarking Civilization has always been somewhat of an oxymoron – for a turn based strategy game, the frame rate is not necessarily the important thing here and even in the right mood, something as low as 5 frames per second can be enough. With Civilization 6 however, Firaxis went hardcore on visual fidelity, trying to pull you into the game. As a result, Civilization can taxing on graphics and CPUs as we crank up the details, especially in DirectX 12.
Perhaps a more poignant benchmark would be during the late game, when in the older versions of Civilization it could take 20 minutes to cycle around the AI players before the human regained control. The new version of Civilization has an integrated ‘AI Benchmark’, although it is not currently part of our benchmark portfolio yet, due to technical reasons which we are trying to solve. Instead, we run the graphics test, which provides an example of a mid-game setup at our settings.
At both 1920x1080 and 4K resolutions, we run the same settings. Civilization 6 has sliders for MSAA, Performance Impact and Memory Impact. The latter two refer to detail and texture size respectively, and are rated between 0 (lowest) to 5 (extreme). We run our Civ6 benchmark in position four for performance (ultra) and 0 on memory, with MSAA set to 2x.
For reviews where we include 8K and 16K benchmarks (Civ6 allows us to benchmark extreme resolutions on any monitor) on our GTX 1080, we run the 8K tests similar to the 4K tests, but the 16K tests are set to the lowest option for Performance.
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.

Civilization 6 Conclusion
In all our testing scenarios, AMD wins at 1080p with minor margins on the frame rates but considerable gains in the time under analysis. Intel pushes ahead in almost all of the 4K results, except with the time under analysis at 4K using an R9 Fury, perhaps indicating that AMD is offering a steadier range in its frame rate, despite the average being lower.

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!
