As you know, it is the graphics subsystem that determines the performance of the entire platform in the majority of contemporary games if the platform has a fast enough processor. Therefore, we select the most CPU-dependent games and measure the frame rate in two test modes. For the first mode we use lower resolutions and disable full-screen antialiasing, so we could see how well the processor can cope with gaming loads in general. This provides some insight into how the tested CPU is going to behave in the nearest future when it is accompanied with faster graphics cards. The second test mode refers to real-life settings: Full HD and maximum FSAA. In our opinion, these results are no less interesting as they demonstrate clearly the level of performance we can expect from contemporary processors today.
Full-HD with maximum visual quality settings:
Top Core i5 and i7 models are comparable in modern games, and the Devil’s Canyon release doesn’t change anything in this respect. As you can see in the charts above, the largest gap amounts to 3% only. Preferring the Core i7-4790K to the Core i5-4690K doesn’t make much sense for a gaming computer, especially as these processors get even closer to each other in performance when overclocked.
It is next to impossible to see any gaming benefits from switching from the older Haswell to the newer Devil’s Canyon products. The only fact we can draw from the results is that the AMD FX-9590 is inferior to Intel’s Core i5 and i7.
Lowered resolution results:
If we lower the graphics subsystem load by reducing the display resolution, we get more interesting results. The Core i5-4690K is now an average 2% faster than its predecessor. The senior model, Core i7-4790K, beats the i7-4770K by as much as 12% thanks to its much higher clock rate. The gap between the two Devil’s Canyon models is 13% on average but varies from 3% to 33% depending on how well the game engine is optimized for multi-threaded CPUs. So it looks like the Core i7-4790K has considerably higher gaming potential than its cousin or predecessor but the GeForce GTX 780 Ti isn’t fast enough to match it. Well, the next generation of graphics cards is already waiting around the corner.
