Core i7-5930K vs. Core i7-5820K - Content Creation performance analysis
Category : Content Creation
Published by Hiwa Pouri on 07.01.15
There is a variety of customer groups, which demand as much power as possible from their computers in order to accelerate processes in order to become more efficient and in the end increase revenue or add additional value to their projects. Especially in the field of content creation, which includes editing pictures and videos or even rendering a complex scenery with beautiful effects, will benefit largely from fast processors as well as a powerful underlying system architecture. With this series of articles we're going to compare two processors with every single article. The CPUs tested are being run at stock clocks as well as overclocked and apart from that we will also vary the memory frequency. It is our goal to show in depth which CPU is how much faster or slower than another one.

Conclusion
Default
First of all we’re going to have a closer look at performance differences with standard clock speeds. From our overall performance rating we see that the Core i7-5930K is on average
3.66 % quicker than the Core i7-5820K. Both processors come with six cores and twelve threads,
the difference between the two processors are the default base frequency where
the
5930K is 200MHz faster than the 5820K which is 3.3 GHz without Turbo Frequency,
other than that difference between two six core processors is number of
PCI Express Lanes the rest of the specification are exactly same.
If we start searching for the benchmarks with best possible scaling on the
i7-5930K, then we find that Cinebench 15 runs 14% faster on this CPU, Sysmark
Media Creation is about 12% quicker, SiSoft Sandra Cryptography gains an
additional 11% and HWPrime gets boosted by 10%. All other benchmarks benefit by
between 0.5% and 3.5%.
We also had a closer look at power consumption and in idle we notice that our test setup with Core i7-5930K was burning
6.90% more power than the same system equipped with Core i7-5820K. In case of load power consumption the difference was
3.87%.
4.2 GHz
Overclocking both processors to 4.2GHz basically shows
less than 1% gain between the two CPUs as they are both six-core processors and the
difference in number of PCI Express Lanes doesn't make any performance gain.
A closer look at power consumption reveals that overclocking these CPUs make for
quite a difference. With the Core i7-5930K we see system power consumption rise
by no less than 24.47% under load, when comparing with the default power
consumption values. In the case of the Core i7-5820K system power consumption
goes up by 20.44%, when the CPU is under full load. In idle the differences are
60.29% (5930K) and 72.73% (5820K). This clearly shows that from an efficiency
point of view, overclocking these processors is not attractive.
4.2 GHz DDR4-3000
Having arrived at this point we’re not going to go through every single benchmark anymore since the overall results are still very similar. What’s much more interesting now is checking what performance differences there are when running DDR4 memory at 2133MHz and 3000MHz with both processors.
Overclocking the system with the Core i7-5930K inside we notice that the performance goes up by
2.03%. In the case of the Core i7-5820K the difference is 2.22% on average. If we go and look out for the benchmarks and programs that benefit the most from increased memory clocks, then we see that
3Dmark 11 Physix performs 7.74% quicker with the memory at 3000MHz and in combination with the Core i7-5930K. In the case of the i7-5820K the same benchmark benefits by 2.43%. WinRAR appears to be scaling excellently on both CPUs whereas the i7-5930K benefits by
7.78% and the i7-5820K by 8.78%. Also the results gathered with SiSoft Sandra
Cryptography show 7.80% scaling on the i7-5930K and 8.10% on the i7-5820K. Apart from the applications that show scaling there is also Sysmark, which on average benefits by between two and three percent from the increased memory clocks on both processors.
Looking at idle power consumption, the system with Intel Core i7-5930K turns
11.93% more energy into heat, whereas with the i7-5820K consumption goes up by
9.09%. Under full load the differences are 5.96% in the case of the i7-5820K and
6.84% for the i7-5930K.
Recommendation
The performance differences between the
two CPUs we've had a closer look at here are minimal. The reason for that is
very simple, since the Core i7-5930K clocks only a little bit higher. If you're
thinking about buying a Core i7-5930K over an i7-5820K we would recommend you to
do so if you're going to assemble a system which benefits from the full 40 PCIe
Lanes. Otherwise spending an additional 182 Euro is simply not worth the 3.66%
more performance you get.
