Benchmarks: Civilization, Total War Attila
The R7 360 was good for 39fps at 1080p in Civilization: Beyond Earth, 11% faster than the GTX 750 Ti. However, the R7 370 didn't fare quite as well falling short of the GTX 950's 51fps by an 8% margin. The R9 380 once again took control over the GTX 960 as it was 4% faster. Finally, the R9 390 was just 1% slower than the GTX 970.
Increasing to 1600p we found the R9 390X and GTX 980 delivering the exact same performance with an average of 69fps each. The Fury X was also 3% faster than the GTX 980 Ti, though with 89fps it was just 3fps faster.
The 1080p resolution proved too much for the sub-$150 GPUs and while the R7 360 was 7% faster than the GTX 750 Ti, it only managed an average of 16fps. The R7 370 was crushed by the GTX 950, delivering 14% less performance for an average of just 19fps. That said, the GTX 950 wasn't exactly smooth with 22fps.
Moving up to the R9 380 vs. GTX 960 battle we are on the edge of playable performance and for the first time the R9 380 is slower than the GTX 960 -- 7% slower, in fact. The R9 390 was also 11% slower than the GTX 970 which managed an impressive 44fps.
Playing Total War: Attila at 1600p using the maximum in-game setting puts a huge load on the system, the result being that high-end graphics cards such as the R9 390X average just 28fps and this meant it was 7% slower than the GTX 980 which offered just 30fps.
The R9 Fury X managed 37fps, just 3% slower than the GTX 980 Ti's 38fps average.
