CPU Benchmarking - Quad vs. Dual in various RPGs
#11
Dark Chronicle is nice but I haven't played it through yet. Besides it US name is actually Dark Cloud 2 as Dark Chronicle is the European Name, don't ask me why they changed it. Well could be that Dark Cloud 1 wasn't released in Europe. Therefore I found a mistake as I used the PAL version of that game and not NTSC.

Xenosaga runs quite well in battles but when you move around it can get slow especially in Xenosaga II. At the beginning even with 4.4Ghz I get only 50 FPS. The GPU is limiting there, yes quite funny that a 260GTX+ might be limiting in a PS2 game Laugh. But I also use 1920x1200 as internal resolution so I shouldn't be surprised. I will try next week to overclock my GPU and test again (GPU easily runs 700/1450/1250).

Mmm, then I might evade Xenosaga ATM, although I never play at that Internal Res if it's not for FFX or X-2 where i've put it at 2048x2048 and still runs quite good.

2048x2048 is pretty high. I tried once 3840*2400 to have real good graphics but then even FF X had slow downs Biggrin. Now I am playing FF XII and there 1920x1200 seems to be too much so I reduced to 1680x1050.

Also..were people actually buying Quads for PCSX2 specifically, expecting to see superior performance compared with similarly-clocked Dual-Cores? Huh

Nice work nonetheless -- it's really nice to see a controlled benchmark showing how much clock speed affects performance. As a Q6600 owner myself (G0 rev sitting at 3.2GHz), I am a bit envious of the monstrous overclocking the E8400 is capable of. Still, I wouldn't consider downgrading just to run PCSX2 a little faster, as it's hardly the primary task for which I use my system Smile

i doubt there are many other people who've actually upgraded to quad/downgraded to dual just for PCSX2. i think its a good test though because there are many, such as you and myself, with Q6600s (except I have a qx6700...pretty much the same thing, though unlocked) and it looks like the performance is almost 1:1 per clock in most of these games with the e8400 in pcsx2, which is surprising.

in some Games the E8400 can even speedup by a few % with same clock speed. I guess this is because each core of the E8400 has more Cache. Might be this helps a little in some games.

If the iCore7 wouldn't require a Mainboard and RAM change I would get one but this way it is too expensive. I will wait for 32nm die-shrink and then try to get one. Because then maybe I can overclock Nehalem to > 4 Ghz as well.

Nice comparision. I'm really tempted to grab a E0 stepping E8xxx CPU and shoot for 500x9 (4.5GHz), my C0 refuses to clock higher than 4GHz without needing a huge bump in voltage, tho I run 500x8 so it's quite efficient nonetheless.

well I don't recommend you to change your CPU as the performance increase from 4Ghz to 4.5Ghz isn't worth it. Most of the time 4Ghz should do fine and if 4Ghz is not enough then 4.5Ghz won't help as well.

Therefore I now wait for 32nm die-shrink and then maybe we can overclock the new iCore7 to such clocks and enjoy another performance step in PS2 emulation Laugh.

Well I'm a benchmarker and overclocking guy, I don't upgrade cuz I'd need it, I just do it for fun and new stuff to play with and this would be a very cheap upgrade if selling my current E8400 too. 500x9 (4.5GHz) would be so sweet coupled with my RAM capable of tight DDR2-1000 config or DDR2-1200 5-5-4-10. My current old C0 stepping E8400 won't get stable at 4.1GHz even at 1.41v, haven't tried any more as it's not worth pushing it further when 500x8 (4.0GHz) runs perfectly stable at 1.36v... the voltage scaling starts running out of the hand at 4.0GHz+.

But yea I'm just gonna wait for i5 (Lynnfield) mainstream version of i7 most likely seeing how great ES samples are doing. It's not that far away, should be released around summertime. Need to upgrade my GPU too, but waiting for some great new performance/price cards and I want it to be newer than HD4870 1GB or GTX 260 Core 216 with at least same or better performance.

Yep. My C0 runs stable at 4GHZ with 1.25V but going above 4GHZ is no go with my CPU even with high voltages..

EDIT: 1.25V @ 9x447. 8x500 works too with higher voltages. Much above 4GHZ not stable no matter what fps,multiplier,voltages I've tried


About benchmark results, there's no big surprises there but nice work with it!

Uhm, Persona 3 runs on my Q6600 @ 4 x 3Ghz with 150fps (even at the School opening scene).

I use the PS2 Playground emulator (and I'm really asking myself why so much people use the 0.95 beta version, because the beta version runs totally unstable on my PC, additionally it's much slower than the Playground version).
