Conclusion

FullHD

Having a closer look at the results measured with FullHD resolution we see, that the performance differences are rather small. Comparing the Core i7-4770K with stock clocks to the Core i7-5820K also running stock clocks we find a difference of 12.08 percent on average. A closer look at the values gathered reveals that GRID Autosport shows the largest difference at this resolution. In this case we're talking about a 15 percent gap between the Core i7-5820K and the i7-4770K. Overclocking the processors to 4.5 GHz we see a bigger difference between the two models, in this case we find gap in games like Sniper Elite 3 and Tomb Raider.

1440p

With the resolution set to 1440p we basically see the same tendencies like with FullHD although scaling with the Core i7-5820K is a little bit better. The average performance difference between a Core i7-4770K and a Core i7-5820K at stock clocks is 11.62 percent. Browsing through all the individual results we again find a spike with GRID Autosport, where the difference is 24.16 percent towards the i7-5820K.

UHD

Also in UHD things are more interesting. Having a look at the average values, we see that the Core i7-5820K at stock clocks is 12.99 percent quicker than the Core i7-4770K with standard settings. The overall results is a bit impressive again, but nevertheless there is an interesting spike again this time. It's again GRID Autosport and Tomb Raider which benefits the most from the Core i7-5820K with a 20 percent difference to the Core i7-4770K at stock clocks.

Power consumption

This is where we really seeing big differences. In idle the system with Core i7-5820K needs 1.49 percent more power and under load the difference is 33.08 percent compared to the i7-4770K. Overclocking the Core i7-4770K to 4.5 GHz makes the system pull 17.91 percent more power from the wall in idle and 9.77 percent more when under full load. In the case of the Core i7-5820K system power consumption goes up by 58 percent in case of idle and 46 percent regarding load.

Recommendation

Overall this round of CPU gaming performance was rather interesting. The average performance difference between these CPUs is 12.23 percent, where as the Core i7-5820K is the quicker one. Comparing prices we see that the Core i7-5820K costs about 13 percent more than an i7-4770K. Only compring CPUs this looks like prices are scaling equally with performance. But if you actually go and buy an i7-5820K you will also have to choose a X99 motherboards as well as DDR4 memory, which are more expensive than Z97 and DDR3 memory. Basically it can be said, that X99 is the more future proof platform at this time, but you also have to pay for that.
