Very well.

Pentium G630
Phenom II X3 720
Pentium G840
Pentium G850
Pentium G860
i5-2415M
And so on.
Is that a joke? http://www.cpubenchmark.net/low_end_cpus.html are the 300 bottom ones.
As NaturalViolence said , "cpubenchmark.net" is not reliable , a lot of BM results are incorrect . I rather go to notebookcheck.net
Pentium Gxxx series are based on Sandy Bridge architecture , not the old Pentium Wolfdale . Pentium SB might run dolphin as fast as your i7 920 (clock for clock) or even faster
But those Pentium are not OCable

Well of course bottom of the barrel 7+ year old cpus will perform poorly with any software, but that has nothing to do with the point at hand. You can't just say "well the top end performs well in both and the low end performs poorly in both, therefore all of the results correlate well", that would be very poor logic. A lot of the results don't correlate well with dolphin performance so stop telling users that they will get good performance if there cpu reaches a certain passmark score. There are cpus scoring 6000 on that list that run dolphin slower than cpus scoring 3000 on that list, you cannot ignore this fact no matter how much you try and twist my words or change the subject.

So with that in mind would you kindly care to address the rest of my post?:
Quote:Compare a hexacore sandy bridge like the 3930K against a quad core sandy bridge like the 2600K in passmark. The hexacore chip performs 50% better in passmark because it has 50% more cores and passmark is a heavily multithreaded application. But do you honestly think that the hexacore chip will perform 50% better than the quad core cpu in dolphin, an application that only uses 2 cores?
Hint: The answer is no.

You want some more specific examples?
Bulldozer FX6100, FX8120, and FX8150 perform better than phenom II X6 or phenom II X4 in passmark but worse in dolphin.
Core i7 980 beats the 2600K and 2500K in passmark, but the 2500K and 2600K are a lot faster in dolphin.
AMD llano quad core and phenom II X4 beat desktop core i3 sandy bridge cpus in passmark. But desktop core i3s beat the living shit out of llano or phenom II X4 in dolphin.
And on and on and on.
Just take a look at the cpu in the 4,000-6,000 point range. Half of those cpus perform poorly with dolphin the other half perform well.
Hexacore opterons and core i5 quad cores both score in that range but core i5 quad cores are wwwaaayyyy faster in dolphin.

Dolphin doesn't care how many cores you have, how fast your SSE engine is, how fast the FPU is, or any of these things that clearly make a big difference with passmark. Passmark is a totally different type of application.

Just to name a few that score under 3,000 points yet perform extremely well with dolphin (faster than a lot of the cpus that score above 5,000 points).

And here are some examples from that same range that perform very poorly with dolphin.
Opteron 1354
Opteron 1356
Opteron 2380
Opteron 1352
Phenom 9650
i5-2557M
A8-3500M
And so on.

And a lot of those cpus perform moderately well.

Good god, look at how innaccurate those results are. G850 outperforms the G860 in passmark. It's the same chip except the G860 is clocked at 3.0Ghz instead of 2.9GHz. How do you explain stuff like that? The results are filled with major anomalies like that. Passmark has a terrible reputation as a reliable benchmarking utility, everybody knows that (except a few people apparently).

Better yet type passmark into the forum search, go on, do it. Then type in "passmark good" into google, or something along those lines and you'll see for yourself how great its reputation is.
Quote:The fastest cpus on the market usually perform well in all software because they don't cut corners anywhere (lots of cores, big cache, high clock rates, high IPC, etc.), but this has nothing to do with the point at hand. Lower end cpus have to cut corners and make tradeoffs. Some tradeoffs will not decrease performance very much if at all in some applications while having a huge performance hit on other applications. Many cpus perform far better in certain types of applications that play to there strengths well. For example dolphin will perform the same with a triple core, quad core, hexacore, or octacore cpu if all the other specs are the same. However a multithreaded video encoder may run twice as fast on the hexacore cpu vs. the triple core cpu.

Therefore it is far more reliable to use the results of actual dolphin users and the knowledge of experienced users and developers than some totally unrelated highly multithreaded unreliable synthetic application.

Don't tell users that they need a certain passmark score to get good performance with dolphin, that is just wrong on so many levels.

Experienced users on this forum have a general idea of about how well a particular cpu should perform with a particular game based on how demanding that game is, what architecture the cpu uses, and what clock rate the cpu is running at. A lot of us are so good at it that we can tell if the users system has a problem like background applications running or overheating just from the users reported performance. You also have to check for gpu bottlenecks, but that's easy as long as you ask user to provide there graphics card info. and there settings. If the gpu is not the bottleneck and they are getting 20 fps in a game that their cpu should be able to run at 40 fps then you know something is wrong. Please spend some time browsing through the forums, you'll see what I mean.

Quote:the cinebench r10 singlethreaded benchmark gives the best result which is comparable to dolphin...
it perfectly shows how the i-serie is superior to any other cpu

the singlethread benchmark is perfect for dolphin...

Much closer since it's single threaded but still not perfect. Cinebench relies a lot more heavily on FPU and cache performance than dolphin does.
Could the original poster or someone upload a new list of games that werent running correctly? I would rather appreciate that greatly.Smile
Unless my cache makes much difference, I've set my i5 to 2 cores, no turbo, and 2.4 ghz before, and every GameCube game I've tried like that works fine on hle.

Wouldn't that theoretically mean that the Celeron G530 would be passable for dolphin?
(Definitely PCSX2.)
DUDE!!!! You have better specs than me! And I am barely able to play Dolphin at 80-90%! Yes Celeron G530 should work just fine! You still have to remember, Dolphin doesn't have a final emulator like some other emulators have for other systems. It's still in devlopment. But with the right configurations, your games should run 90-100%! If you doubt me, how about we trade? Dodgy
