Why in most of gaming benchmarks(GTA V, AC Unity, etc..),intel core i7 6700k have more fps than 5820k?

ExtendLord · Jul 1, 2016

6700k have 8MB cache, 4 cores and 8 threads and clock speed 4GHz.
5820k have 15MB, cache 6 cores and 12 threads and clock speed 3.3GHz.
5820k have more 4 threads and more 2 cores, its strange that 6700k have more fps.
Can someone explain me why?

because most of the games do not need over 4 cores/threads and will perform better on faster cores.
4GHz is significantly faster than 3.3

Most games depend on the performance of a single master core.
The individual cores on the 6700K are faster at stock, and can be overclocked higher.

Few games can make use of more than 2-3 cores, so the 6 cores of the 5820k are not that useful.
Actually, for gamers, the extra hyperthreads of a I7 compared to I5 are not that useful either.

And yet a 4790k beats them both.

The number of cores/threads means almost nothing in the majority of games (unless you are talking about less than 4).

Single threaded performance is what matters here, the 6700k is faster than the 5820k.

most of the time it's to do with 'single core perfomance'

Most I5's have four cores, with no HT. And even though they have less cores, the often outperform those higher end CPU's in gaming metrics. This is because they have faster single core performance. As games become more reliant on more than 4 cores for top gaming, those other CPU's you mentioned will shine.

Right now, there is no need for anything more than an I5 for gaming, and an I7 for anything like video editing, streaming etc.

n0ns3ns3 :

and if games could use more than 4 cores/threads
will 5820k be better than 6700k?

n0ns3ns3 · Jul 1, 2016

only in a specific scenarios.
That's why, for gaming only, i5 is the best.

n0ns3ns3 :

why only in a specefic scenarios and not everytime?

ExtendLord :

because multithreaded applications will work faster with a 5820K then, since they will use all (?) the cores/hyperthread cores and it has more than the 6700. The more you have running at the same time, the better the 5820K will handle them.
Remember: benchmarks are just benchmarks, not real use of a rig.

it means that every game that can use more than 4 cores/threads, 5820k will run then better, no exception(same pc but other cpu) right?

I'll simplify.
6 cores would be always better than 4, if per core performance is the same (for example: same architecture + same clock speed).
in any other case, the answer is "it depends on so many things, that you can not only test to find what application will perform better with what CPU"

ExtendLord · Jul 1, 2016

n0ns3ns3 :

it depends on what?(cpu only,other specs will be exactly the same)

n0ns3ns3 · Jul 1, 2016

depend on what part of CPU (or system) application is sensitive for.
Take an example.
Is V6 engine is always better than V4 ?
what is they are diesel ? or turbo ? or twin turbo ? or one is way more efficient than another ?
Which one will be better for street racing, pulling cargo, off road ?
