Inconsistent Speeds in Wii Games

[Visionary]

Hello Everyone!

I have been playing Gamecube games on Dolphin for a while and have been able to run them all at the highest settings. I recently bought a big enough flash drive so I can now rip and play my Wii games. The problem is that I have to have the lowest settings just for them to run. For example in Super Mario Galaxy, i get 100% speed when standing still, but as soon as I start moving and playing the game my speed hangs between 50-95% with major lag spikes here and there. I have been told that my system is more than enough to run these games fine, but its just not working.

My Rig:
-AMD FX-8320 (8 core) @ 4.1ghz
-Cooler Master hyper 212+ cooler
-G.Skill Ripjaw RAM 8gb at 1600mhz
-MSI Hawk Radeon HD 7870, 1220mV, Core Clock 1170MHz, Mem Clock 1320MHz
-Seagate barracuda 1tb HDD 7200rpm
-750w Thermaltake PSU
-Rosewill ThorV2 case

EDIT: Forgot to add that im running Dolphin 3.5-606

AMD FX-8320
Super Mario Galaxy

Overclock your CPU ! Your CPU does not stand a chance aganst i5 2400 in Dolphin (Yes we have benchmark data)
i5 2400 is not strong enough to run SMG full speed
If you used LLE backend , you would get lower speed

I have been told that my system is more than enough to run these games fine

For most games , yes
SMG is out of your league

How is my processor not enough to run this game? It is an 8 core 4.1ghz processor that was supposed to be top of the line.

In these benchmarks it seems to compare fairly well against the i5 2400. http://www.cpu-world.com/Compare/357/AMD...-2400.html

What do I need to do/buy to make it work?

It is an 8 core 4.1ghz processor that was supposed to be top of the line.

It's a midrange cpu from AMD. Clock rate and number of cores are not the only factors that determine performance. Piledriver cores handle certain types of code/algorithms very poorly. It just so happens that dolphin contains a lot of the types of algorithms that the architecture is not well suited to.

In these benchmarks it seems to compare fairly well against the i5 2400.

It depends on the application.

Overclocking will help a bit. But beyond that there is nothing more you can do other than swap out your motherboard and cpu with an Intel ivy bridge cpu and LGA1155 motherboard.

Look at post #137
Dolphin is a dual core application . Bulldozer/Piledriver are bad at single threaded performance that's why

Well shucks... I guess I am going to start looking at new motherboards and CPU's.

You should wait next gen - Haswell i5 4670k or i7 4770k CPU (June-2013)

Sweet, I will be looking forward to getting the next gen of intel!

Alright so it is 7 months later, what is the latest news as far as this information goes? Should I wait until the next generation of intel processors come out in 2014, or should I get a nice haswell cpu and motherboard for Christmas? Dolphin emulator 4.0 has been out for almost a month, so I figured I should see what you guys say before I drop more money into my rig.

Is it safe to say that for best single thread performance I should stick with Intel?
