Dolphin, the GameCube and Wii emulator - Forums

Which is the better CPU?  I know the 5820K is a 6 core CPU but the 6700K is skylake based.  Is Skylake as big an improvement in IPC as Sandy Bridge to Haswell? 

Skylake isn't a huge improvement, but 6 cores won't really help either, I'd go with which ever is cheaper.

But is the improvement as much as from sandy bridge to haswell?

You're jumping from 1 generation with haswell to skylake. You're jumping 2 generations with sandybridge to haswell

According to users Skylake is in average only 5% faster.
But if you look at CPU frequencies, you should definitively take the 5820K : more computing power when not overclocked. If Dolphin is your priority, that is. For PC games (that tends to use more cores with DirectX 12) and multithreading software, the 6700K is better.

Here is Dolphin Benchmark for i7 6700k

As you can see , Skylake is just slightly faster than Haswell while Haswell is 30% faster than Ivy Bridge/Sandy Bridge

DrHouse, that makes no sense as the 5820k has 6 cores while the 6700k has 4, so if PC games take advantage of more cores, how is the 6700K better?

I would go for the 5820K as the price is the same or lower than 6700K but you get 6 cores/12 threads instead of 4/8 and it is overclockable as well.
When you overclock 5820K you will be able to run any dolphin game at max speed and modern PC games like GTA V will run better on 5820K.
Also 5820K has more pci-e lanes so it is better for multi GPU setup.
Add to that quad channel vs dual channel memory and you have the winner...
Even though the 5820K is an older CPU it is more future proof than the 6700K.

Agree but X99 mobo for i7 5820k is not cheap !!! It's twice as expensive as a normal Z97 / Z170 mobo

True but you also get more features with X99 board.
Even cheapest X99 board has SLI support where with Z97/Z170 you have to go for the more expensive ones.
