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
i7-5930K with stock clocks to the Core i7-5960X also running stock clocks we find a
difference of 3.04 percent on average. A closer look at the values gathered
reveals that Battlefield 4 shows the largest difference at this resolution. In
this case we're talking about a 12 percent gap between the Core i7-5960X and
the i7-5930K at stock clocks. Overclocking the processors to 4.5 GHz there is only
2 percent difference.
1440p
With the resolution set to 1440p
we basically see the same tendencies like with FullHD although the difference
bewtween two CPUs are very small. The average performance
difference between a Core i7-5930K and a Core i7-5960X at stock clocks is only
2.7 percent. Apparently this is virtually nothing. Browsing through all
the individual results we a spike with Assasins Creed Unity, where the
difference is 6.61 percent towards the i7-5960X.
UHD
Even at UHD things are not becoming more interesting.
Having a look at the average values, we see that the Core i7-5960X at stock
clocks is 4.45 percent quicker than the Core i7-5930K with standard settings.
The overall results might not be impressive again, but nevertheless there is an
interesting spike again this time. It's Watch Dogs where we see a 12.95 percent
gain and Metro Last Light with 9.58 percent performance difference. This is actually
quite something if we consider that only the CPU is different in the our test
system.
Power consumption
This is where we start to really see big differences.
In idle the system with Core i7-5960X needs 31.4 percent more power than the same
system with Core i7-5930K and under
load the difference is 7 percent. Overclocking the Core i7-5930K to 4.5 GHz
makes the system pull 54 percent more power from the wall in idle and 13 percent
more when under full load. In the case of overclocking the Core i7-5960X to 4.5
GHz system power
consumption goes up by 85 percent in idle and 8 percent regarding load.
Recommendation
Overall we see that CPUs
aren't bottlenecking todays gaming rigs. Even at FullHD the impact of a faster
graphics card is much bigger than the CPU. Nevertheless
it was interesting so see that there are some games where the framerates at UHD
are quite a few percent higher when using an i7-5960X. Therefore the addtional
two cores and four threads as well as the larger L3 cache are helping.
Should you be thinking
about buying one of the CPUs we've had a look at in this article, we can tell
you that the performance difference in the case of gaming is marginal. Considering
that the Core i7-5960X costs 80 percent more than a Core i7-5930K the average
performance difference between 3 and 5 percent in the case of gaming simply
can't be justified. For gaming a Core i7-5930K is definitely more than
sufficient.
