How bad is the bottleneck today? Well, it all depends on how bad you are at pairing hardware. Any experienced system builder will tell you that it is important to build a balanced system, especially if you want the best for your money. In this article, we'll take a look at today's bottleneck, be it CPU or GPU bottlenecks, and test a variety of games: some old, some new, some CPU-bound, and some GPU-bound.
We selected several different CPUs for the benchmarks and tested them with the GeForce GTX 1060, 1070 and 1080 at 1080p. This should give you a pretty good idea of what kind of CPU and GPU pairing makes sense for your budget and the games you want to play.
It'll also show us how much lower CPUs like the G4560 and Ryzen 3 1200 limit the performance of high-end GPUs like the GTX 1070 and 1080, if you're crazy enough, a $ 100 CPU with a 400- Pair dollar CPU + GPU.
Towards the end of the benchmarks I will also check some overclocking results …
Test system specifications
In Battlefield 1, using the GTX 1060 makes no difference in performance between the different CPUs. The G4560 corresponds to the Core i7-7700K with at least 71 fps and an average of 80 fps. Admittedly, in the heat of a 64-player fight, you may see a greater variance, but unfortunately it is not possible to benchmark exactly. However, I personally found the combination of G4560 and GTX 1060 to be acceptable for multiplayer action, and you certainly can't complain about the price.
When upgrading to the GTX 1070, we notice a real separation between the different CPUs tested. The 7700K is now up to 28% faster than the G4560, although the Ryzen and Core i5-7400 CPUs still look pretty good.
As soon as we switch to the GeForce GTX 1080, things change significantly as the 7700K offers up to 50% more power than the G4560 and even 20% faster than the Core i5-7400. As expected, for high-end GPUs, you really need a powerful CPU to take full advantage.
It continues with the results of F1 2016. I am using the older version 2016, since F1 2017 came out shortly after I had collected most of these results when testing the Ryzen 3 CPUs. Still some interesting results. Although we see the same average frame rate of 71 fps on most CPUs tested with the GTX 1060, there is a slight difference in the 1% low results.
As soon as we switch to the GTX 1070, things change massively. Here the G4560 really falls behind, especially when you consider the 1% low result. Here it was 33% slower with only 55 fps than with the 7700K's 83 fps. Nevertheless, the processors Ryzen and Core i5 fit together quite well with the 1070.
However, once we switch to the GTX 1080, the 7700K is completely unleashed, and now you can see that it is 1400 miles ahead of the Core i5-7400 and Ryzen 5. The 7700K was almost 80% faster than the G4560 was a true sign of dominance.
With Total War Warhammer we are returning to extremely CPU-demanding titles, and as such, even the GTX 1060 shows the shortcomings of the G4560 as a lower-clocked dual-core CPU. As soon as we switch to the GTX 1070, we find that the Ryzen 3 and 5 CPUs are not really able to increase the performance compared to the GTX 1070. We have found that this is due to the way Nvidia's drivers handle the DirectX 12 API.
At least that's not the focus of this video. Even if we look at the Core i5 and Core i7 processors, there is now a certain separation in the GTX 1070. This is reinforced by the GTX 1080, and now the 7700K is almost 30% faster than the Core i5-7400 and 71% faster than the G4560.
