Ok, now that makes sense. The article I read wasn't very specific.
So PCSX2 isn't entirely LLE huh? Interesting.
Now that I think about it I'm entirely certain what I read was on the PS3.
Sorry I thought I could go to best buy and buy a high end graphics card and put it in my computer :/ anyway I just wanted to know of this laptop: P580-308725U would run better or worse than this laptop: V3-551-8887. Since intel graphics are bad and AMD graphics are good, I am curious. I am doing this on my iPod touch so I don't have my own computer yet, so I am looking to buy one that can run dolphin 720p for a good price. Does anyone know Andy other laptops I could get? Also does getting Windows 8 Pro make dolphin run faster?

Warning : Multimedia Laptop cooling is bad for heavy gaming such as Dolphin . They will run hot and maybe overheating -> Dolphin might not run well
Either buy a gaming laptop (>1200$) with dual cooling fans such as Asus G55VW or build a decent desktop
I'd have to agree - running high end emulators on laptops is a dangerous game. I remember there being an article on LifeHacker the other day that showed how for the price of a high end laptop that could do anything you'd want it to, you could build your own high end tower PC and buy a mid end laptop that was much more portable and both would last longer than pushing the high end laptop to its limits.
A lot of my friends go that route, and use something like gotomypc to play remotely. Now I know for Wii games that might not work as well, but it's something to consider. I don't think Wii games are best played on a laptop anyways :p
PCSX2 has the MTVU speed hack, which takes advantage of CPUs with more than three cores, and can give a huge boost in speed, but with my CPU, I can tell a difference. As for Dolphin, the closest feature I can think of is the so-called LLE on thread, but I don't think it helps at all. In fact, it doesn't do jack squat.

It does make a big difference in scenarios where DSP emulation is the bottleneck.

MTVU stands for multithreaded vector unit, it allows the two vector units to be emulated by two seperate threads. In a scenario where the VPU thread is the bottleneck this will improve performance.

I might consider the Lenovo in the newegg link, but If I had the money ($1000) or saved up would a laptop from ibuypower.com be a good choice?

Link ? Specs ?
The MTVU hack from PCSX2 only is best optimized for 3 cores, any more than that would be useless. But some games doesn't benefits from this hack at all. As a matter of fact, i get lowered fps when this hack is turned on for this one particular game, Zone of the Enders: The 2nd Runner.
I find it funny how both sides of the emulators said their emulator is more demanding or more complex than the other emulator, i.e. dolphin and pcsx2. The Devs at pcsx2 said that PCSX2 is technically more advanced than Dolphin due the complex nature of the ps2 hardware. They also said, Pcsx2 is more demanding than in the graphical department and on the CPU side as well. And now that I'm here seeing dolphin is also saying the same thing.
Well, technically, i think both emulators are quite demanding when it come to CPU processing power. Not all games can run full speed (unless hacks are involved). Here are some of PCSX2 most demanding games: Zone of the Enders series (1 and 2), All of Metal Gear Solid series, Grand turismo 3 and 4, and Shadow of the Colossus.

Interesting, apparently PCSX2 is not as well multithreaded as I thought. There are at least 6 major components in the PS2 that run in parallel and therefore could be emulated in parallel:
EE CPU
VPU0
VPU1
IOP
GS
SPU
And if SPU emulation where done as LLE that could be further split into SPU0 and SPU1. It seems PCSX2 normally has EE, IOP, VPU0, and VPU2 emulation all on the first thread and GS/SPU emulation on the second thread. MTVU hack splits VPU1 emuation into a third thread.
Threading IOP and SPU probably wouldn't improve performance at all but threading VPU0 should improve performance dramatically in some games. I wonder if the devs have thought about that or if it's even possible.

Well any game that doesn't use VPU1 a lot could potentially run slower since the multithreading adds overhead.

There is no question that pcsx2 is more advanced than dolphin (although the code is much cleaner). It only takes someone 5 minutes of looking at the source code for both emulators to figure that out. The PS2 hardware is more complex compared to the GC/Wii with a few notable exceptions like the GC/Wii DSP (which is more complex than the PS2 SPU). But to be fair the PS2 is a lot easier to tinker with than a GC or a Wii and there is a lot more documentation out there for it.
As for which is more demanding that depends on which games you're playing, what hardware you're using, what revision you're using, what OS you're using, and what settings you're using. Assuming you're using the recommended hacks dolphin is usually a bit slower on average.
