4200Mhz e6300 vs 3915Mhz e8400

[handlebike]

Hello. As the title says, which would provide better performance with Dolphin? An e6300 clocked at 4200Mhz or an e8400 at 3915Mhz. I own both processors so it's not a matter of buying anything extra (just a small time investment to swap it out and overclock).

Well spec wise, the e8400 is much better than the e6300 but I'm not sure if the emulator takes advantage of that (I'm guessing it does). Did you hit a wall getting your e8400 to clock higher? It should be able to hit 4ghz I believe

Yeah, the highest I can push my p43 motherboard is a 1740 FSB so no 4Ghz for me.

Thanks for the reply, but this is the "Pentium Dual Core" (Wolfdale) e6300 that I own, not the Conroe by the same name.

sorry I was misinformed. not exactly e6300 cache, but close enough?

It astounds me that people willingly subscribe to the idea that anything presented on a neat, cogently designed chart is empirical :p
I don't have answers here, I'm just extrapolating an allusion

Still hard to tell without knowing how dolphin will behave with the difference in L2 cache.

Seems like it could be anywhere from a ~7% performance gain to a ~11% performance loss.

I'd pick the E8400 simply because of the 6MB cache and it also have a higher FSB. On the other hand, the E6300 only have 2MB with 1066MHz fsb.

e8400 @ 3.915GHz no question about it. Dolphin will gain a substantial improvement from the 6MB cache (probably around 15-20%) and you will get a memory bottleneck at around 3.8GHz with either cpu so anything past that is effectively pointless.
