Dolphin, the GameCube and Wii emulator - Forums

No problem , friend

I 'm on a rather low budget. I'm thinking of buying the intel i3 3220 dual core processor. What category would it fit into?

Category: Very fast...

Buy Pentium Ivy Bridge G2120 instead of i3 .
Basically , they're the same chip . i3 has Hyper Threading and higher clock rate
But Hyper Threading is useless for Dolphin and 200MHz is not worth 50$ and 200MHz does not make noticeable difference (400MHZ or higher)
Both i3 3220 and G2120 should pair B75 mobo . Do not pair them with H61 mobo because bios update is a pain in the ass
If you choose G2120 , you will save 50$ for a graphic card
If you choose G2020 , you will save 65$ for even better graphic card
Recommend graphic card for 3x or 4x Internal Res (1080p and higher ) : EVGA GTX 650 (100$) or AMD 7750 GDDR5 or AMD 6670 GDDR5

I'm buying the i3 as part of a barebones kit (lazy, i know). I was actually looking for one with the pentium, but couldn't find it. So I settled for the i3. I actually already had decided to buy the evga geforce gtx 650, so no problems there! Thanks for your help.

I have access to a e5-2640 cpu and was wondering how that would handle Dolphin. I realize that the clock speed is rather low, but would the l2 and l3 cache offset that enough? Resolution would be 1920x1080.

Quote:e5-2640

Turbo Boost Frequency :
_3000 MHz (1 or 2 cores)
_2900 MHz (3 or 4 cores)
_2800 MHz (5 or 6 cores)
Since Dolphin is a dual core app , it should boost to somewhere around 2.9-3.0GHz

This CPU should be fine on most games , some demanding games will not run well

Actually, I was wondering if it would be possible to make one of these.
Listing specific models and such for the "Tech" Literate, who know the differences between different CPU models and such but not how they might perform in dolphin vs. other apps/games.

As well as perhaps recommendations for Over-Clocking.

Another thing I wanna note, I think someone should make a proper side sort of spring-off of Dolphin optimized for AMD's current chips, as it's been proven in linux for example that they can do much much better even with the same core count vs. the Intel part.
I didn't come here to argue, I'm just saying.

inb4: Someone starts spouting out non-sense and saying AMD sucks and how I'm being a "OMGS FANBOY".

PS: If cursing is against the rules, I do say I do not protest removing them.

Edited: To sound less obnoxious and buttmad

Wow that post escalated quickly. Anyways, you do realize they run the same architecture, right? The programmers aren't optimizing it for intel, but since dolphin needs 2-3 cores intel chips work the best. That's why octa-core intel chips are really high to buy, and why amd octa-core chips are common. They can't make a better chip, so let's just pile(piledriver) in more cores and give a higher clock rate. It isn't that programmers favor intel in their programming (though that did happen, there was a court case and a law passed against it or something done. Don't feel like looking it up). It's that intel chips are superior. No matter how you put it, they are superior. Both run the same code, just intel runs it a lot better. The only way amd chips are good is the apu's they sell because those are better than the intel hd graphics. And I think the haswell hd graphics are almost equal with those now.
Edit: When I say that's why they're really high to buy, just realized I never elaborated. 4 core i7's performace similar to 8 core amd's. They have alot more performance per core than amd chips.

Read the thread. This has been discussed ad nauseum.

That's completely unrelated to the purpose of this thread and would deserve its own thread. There are so many good OC guides on the web that quite frankly I don't see the point in investing the time/effort into making yet another one.

We're all adults here.

Cruzar Wrote:Another thing I wanna note, I think someone should make a proper side sort of spring-off of Dolphin optimized for AMD's current chips, AMD's design is totally different from Intels, you can either code it properly or be a lazy ass and continue giving them bad rep because you're too fucking lazy to learn anything new and wish to continue re-using the same coding you did on Core 2 since it'll work just fine on the newer Intel chips (or optimizing for Intel and De-optimizing for AMD), not to mention most issues of AMD chips lagging behind are developers coding for Intel then using the most Rock-Dumb un-optimized in your face retarded biasedly slow way possible for the AMD chips when they're detected. I guarentee with proper optimization, I.E. actually coding for the Architecture PROPERLY that the AMD (Bulldozer even, as well as Piledriver, not to also mention Phenom II FFS) processors would keep up just fine with the high-end Intel Chips. kthx

I'm going to go out on a limb here and say that you probably haven't done any assembly programming before. Or any type of low level programming at all. Or any programming period. Definitely at least the first two. You also probably don't have any knowledge of electronic engineering, computer engineering, cpu microarchitectures, etc.

Simply put everything you just said it either completely wrong and/or impossible.

But it is an open source project so feel free to prove the developers (some of which have been writing x86 assembly for over a decade) wrong with your vastly superior understanding of low level optimizations. As well as the engineers at Intel and AMD and every low level programmer out there. Since I'm pretty sure none of them would agree with that post as long as they've had any formal or informal education on the subject.

I've responded to this ridiculous claim (and so have the developers and many other veteran forum members) many times. If I have time I'll do it again for you sometime soon. Or maybe somebody else will beat me to it. We'll see.

Edit: I should also point out that linux builds of dolphin are compiled using GCC, an open source compiler. You sure as hell can't claim that is artificially favoring Intel cpus. Yet we don't see any significant speedup on AMD cpus on the linux build. Which completely rules out compilers "deoptimizing" codepaths for amd cpus like you claim.

Edit 2: For the record I do acknowledge that garrlker has provided a response already. I just don't feel that it has been properly elaborated.

Faster actually. At least iris pro that is.
