Is it true AMD processor is not suitable for dolphin emulator?

[Set@moN]

Since yesterday I was thinking that Intel Cpu's has better performance against Amd ones when playing games on Dolphin. After downloading Revision 4.0.8483 I was able to play all games with a rock solid performance without any noticable issue. With these latest Dolphin revisions I see that there is no reasonable point to change Amd system with an Intel just for Dolphin. I was used Intel many years but I saw that I was wasting unnecessary dollars for playing games and multimedia needs. So I changed my all system in to an Amd and now very happy with getting same performance for my applications without waste more money. Especially I want talk about Dolphin Revision 4.0.8483. Now playing my all games with rock solid 30 FPS. My system has an Amd X4 955 BE CPU, Hd 7850 Gpu and 8 gm Ddr2 Ram. It is good to see optimisations of Dolphin is changed slightly since 3.5. and improving without stop.

There is no such thing like "optimization for AMD CPU" . "Dolphin is a dual core application" is the main reason why Dolphin does not run well on AMD CPU
Rather than making CPU run faster . All these years , AMD made CPU run slower . The worst CPU architecture of AMD is probably Bulldozer (FX-8150 , FX-6100 , FX-4100...) . Bulldozer FX-8150 has more cores than Phenom II x6 but each core is slow ...even slower than Phenom (You can check single-threaded benchmark or Dolphin benchmark on our site) . Most emulator don't care how many cores your CPU has , Dolphin is one of them .
Latest Dolphin run games faster than older dolphin revision , that's why you see an improvement . Not only for AMD CPU but also for Intel CPU as well .
With A10 6790k (Piledriver) @5.0GHz , I can play most games full speed except some demanding games like TLS . The cheaper Haswell dual core G3258 @ 4.6GHz ($65) is almost twice as fast as Quad Core A10 6790k @ 5.0GHz in Dolphin ....
Anyway , If you're satisfied with your CPU then you should not bother to upgrade

Now try an intensive game for Dolphin or just any single-thread application and you'll see the difference right away.

But if you can play your games at full speed, that's good for you. Just please don't suggest that there is now no reason to choose an Intel CPU over an AMD.

Exactly yes and I aggree with you that Amd Cpu's increasing cores but decreasing speed. I have a reasonable good cpu which is working @ 3.6 Ghz. I like performance of it at Pc and emulating applications. But Dolphin forced it so much and I cant play some games. Those games are not many but they are Wii platforms best games I think. After the testing last revision 4.0.8483, I am very very happy with the speed, graphic and sound improvements. I gave an example in another topic in here that yesterday evening I tested Dead Space Extraction. I am very surprised the improvement of optimisation of emulation. Before I got really serious Fps drops in open areas and also with graphical issues including hacks thicked. Now without any hacks I get solid 30-32 Fps. Sometimes drops to 25 Fps when crowded but you cant notice any slowdon or sound shuttering. Before I was using R6515, 3.5.144 and 4.0 but I couldnt play this game due to performance impact. Now I feel the difference so much. I also tested other problematic games too. Just like Cod Modern Warfare Reflex. It has performance issue too for me. Result is same. Rock solid Full speed gaming experience most of time. This is very well improvement for me to continue with my hardware.

Also I noticed that yes Dolphin is a dual core application but sometimes It uses my 3 cores. Also I can only increase Fps when I overclock my first core. Overclocking 2nd,3rd or 4rth core doesnt make any effect to increase FPS. I think first core is used by Dolphin to emulate wii core and other core is emulating Gpu. Isnt it?

One core is used for emulating the CPU, one core plus the GPU is used for emulating the GPU, one core can be used for emulating the DSP if you have it set to LLE, and the other cores are only used for tasks that don't need a lot of computing power.

Dont worry I dont suggest anything between Amd or Intel. Everyone can choose whatever they want. My computer knowledge comes from 8086 & 80286 Intel Cpu's and Cyrix (R.I.P). So I know what I need and expectations since first and second generation pentiums. Now I only think Cost and Efficiency. I wasted many dollars to old Pentium HT's and dual cores before. Now I am happy with Amd and I can feel the warm of my pockets if I get what I need without paying too much.

Now I just want to learn about intensive games. What are they? Just let me make a test and compare with old and this new revision with my cpu. I already tested those and playing full speed mostly;

Angry Birds
007 Night Fire (Full speed with 4.0.8384)
Red steel 2 (Full speed with 4.0.8384)
Dead Space Extraction (Full speed with 4.0.8384)
Cod Modernwarfare Reflex (Full speed with 4.0.8384)
Dinosaur Hunter (Full speed with 4.0.8384)
Terminator 3 Redemption
Metroid Prime Trilogy
Resident Evil Archives
Resident Evil DarkSide chronicles (Full speed with 4.0.8384)
Resident Evil Umbrella Chronicles
Resident Evil 4 wii edition
Wii Fit Plus
Wii Sport
Wii Sport Plus
Wii Play
Wii Play Motion
Virtua Tennis 4

Many more but I cant remember the names. I can play all of them at full speed most time during gaming. Minor fps drops without notice.

Interesting that when I start Dolphin 3.5.144 and start any game as window mode with windows task opened that I see 3 cpu is under usage without LLE. After closing the game window or stop emulating and start again now It is using 2 cores. Everytime this is happening. It is always using 3 cores at first emulation starting. I noticed it when making Oc to my cores seperately. I never use LLE because of the performance impact.

For a similar price point Intel performance is way better in Dolphin, even if many games run well on an AMD cpu nowdays due to emulation speedups, as long as the statement mentioned before stands i don't see a reason to suggest anything else but Intel here. Yes you can run many games fine with an AMD cpu in dolphin but you can run even more better without having to spend way more money going Intel. Especially if you are using a laptop where AMD can't compensate for their poor performance with more wattage like they do with desktop, that combo is the worst you can have in dolphin.

I'm not questioning your computer skills and knowledge, just saying that it still isn't the best idea to use an AMD CPU for Dolphin. Also, as Link_to_the_past mentions, an AMD uses more power than Intel CPUs yet they still have worse performance in Dolphin, so it isn't the most power and cost efficient.

There's The Last Story which is reportedly very intensive, Twilight Princess's Hyrule Field (completely "unlocked") is also quite intensive but not as intensive as it used to be thanks to improvements.

Well, here's the difference: a good Intel CPU will be able to run those at full speed even in the most intensive parts, not just "most time". Even with LLE (although that's less useful nowadays with most games as HLE gets better).
