Conclusion

Let’s have a closer look at the results gathered, while testing these CPUs in games with FullHD resolution and maximum details. Overall our test system with Core i7-4790K performed 2.4 percent quicker, than the same system using the Core i7-4770K as a basis. Overclocking the Core i7-4790K from the stock 4.0 GHz to 4.5 GHz, or in other words by 12.5 percent, made the gaming performance go up by 2.8 percent. In the case of the Core i7-4770K increasing the clocks from the stock 3.9 GHz to 4.5 – 15 percent overclock – conjured on average 3.3 percent more FPS on our screen.
If we start looking for the most surprising results, it doesn’t take long until we find that Battlefield 4 appears to be the only game, which properly scales with CPU clock speeds. Overclocking the Core i7-4790K to 4.5 GHz makes the frame rates increase by 10.3 percent and in the case of the Core i7-4770K we’re even measuring a 14.3 percent fps bump.

Another point, which is always interesting to have a look at, is power consumption. Equipping our system with the Core i7-4790K and running it in idle, caused our system to burn away 78 Watt and under load the value went up to 392 Watt. Equipped with the Core i7-4770K we see 76 Watt idle power consumption and 388 Watt under full load. Comparing the two systems, the one equipped with Core i7-4790K burns 2.6 percent more power in idle and 1.0 percent more under load.

If you bought a Core i7-4770K a while back, then we can tell you without the shadow of a doubt, that there is absolutely no need to get rid of it and replace it with a Core i7-4790K. From a gaming performance perspective it really doesn't matter which of the two CPU's you have in your system. Apart from this, we found that in Switzerland there is almost no price difference between the i7-4770K and the 4790K but when you compare prices of these to CPU's in Europe you see that the Core i7-4770K goes for 27 Euro less. Should be planning to upgrade your rig with a CPU that supports HT and eight virtual threads and should you be situated in a country, where the 4770K goes for less than the 4790K, we recommend to go for the 4770K. On another note we have to mention that the i7-4790K runs considerably cooler than the i7-4770K which makes it easier to overclock the 4790K using aircooling.
