Last summer we published a similar series of articles, where we were analyzing gaming performance on the basis of two different processors. Back in the days it became very clear that performance differences between two CPU's at high resolutions are close to zero. The reason for this can be found within the fact, that the processor isn't the bottleneck of a system, when you're playing games at high resolutions. In this case it's the graphics card, which has to work overtime. In case of lower resolutions the influence of the processor becomes clearly visible, since the graphics card isn't the limiting factor anymore.

Having a closer look at the results we gathered while testing eight different games and two different benchmarks with two different presets, we see that the Core i7-4770K, with our "low-preset" is on average 4.1 percent faster than the Core i5-4670K. Switching to our "high-preset" makes the Core i7-4770K's performance benefit melt to a mere 0.17 percent. Like we've already mentioned, this difference can be explained by the fact, that the CPU isn't the bottleneck in this case. Overclocking the Core i7-4770K to 4.5 GHz makes the performance with our "low-preset" go up by 11 percent but when it comes to the high-preset the increase in performance is only 1 percent. Regarding the Core i5-4670K the situation is similar (8.8 percent "low-preset", 0.8 percent "high-preset"). What's quite interesting to see is how the wattage of our test system increased while maintaining 4.5 GHz stably. The 4770K needed 40 percent more power and in case of the 4670K the increase was 30 percent.

Should you be looking for a gaming rig these days and ask yourself what CPU you should buy, then we can say, that the Core i5-4670K will be as sufficient as the i7-4770K. From a gaming performance point of view it really doesn't matter which of the two CPU's you buy. On the other hand, if you consider the price difference between these two CPU's, then the i5-4670K is almost 90 Euro cheaper and the i7-4770K. In case of a gaming PC the i5-4670K is definitely more value for money and the i7-4770K only makes sense, when you actually run applications, which benefit from eight virtual cores.
