My brother wanted me to see if his CPU could unlock and overclock so I tested it in my system since his cheap MB could do neither. I thought Why not run this benchmark while I'm at it. The only thing changed between this test and my last one is the CPU.
First no tweaking just stock cpu.
OS: Windows 7 home premium x64
CPU: Phenom II x2 550 (Stock 3.1Ghz)
GPU: Gigabyte GTX 660 2GB GDDR5
RAM: OCZ Gold 8GB DDR2
Dolphin: 64bit From this thread only options changed where the ones Starscream changed.
GAME: NTSC
I resized the images this time so I will type out the FPS incase it's hard to read.
First Save. 40 FPS
Second save. 31 FPS
Third Save. 49 FPS
Now you may be thinking this is the practically the same as the 1100t and in fact when I first opened the first save I was pretty disappointed. However, though a single pic can't show this, the framerate was not nearly as stable. Though the FPS In the pics was the most prevalent there would be short dips in fps by as much as 10 - 15 frames. Where as the 1100t was pretty rock solid with there only being about a 1-2 fps change in both directions.
Now for the Same tests with the CPU unlocked to a quad core.
OS: Windows 7 home premium x64
CPU: Phenom II x4 B50 (Stock 3.1Ghz, same CPU as before but Unlocked)
GPU: Gigabyte GTX 660 2GB GDDR5
RAM: OCZ Gold 8GB DDR2
Dolphin: 64bit From this thread only options changed where the ones Starscream changed.
GAME: NTSC
First Save. 42 FPS
Second Save. 35 FPS
Third Save. 57 FPS
Again what can't be seen in the pics is how much the FPS changes. Unlocking to a quad brings back the fps stability that the 1100t had. No more large drops in fps. The fps was generally within 2 of what the pic shows. The only exception is the third save. It was consistently between 50 and 57 but never really on anything long enough to call it prevalent.
So what have I learned, and maybe you all knew it already?
1. A couple hundred Mhz is pretty much negligible for phenom II cores, at least as far as Dolphin is concerned.
2. Even though Dolphin only runs on two cores, excepting LLE on thread. A similarly clocked Phenom II x2 can achieve virtually the same FPS in theses examples however it can't maintain them as well as an x4 or higher.
3. It seems TurboCORE wasn't really doing anything for me. I was using the stock HSF though. Ill test again with better cooling.
I am curious as to how a similarly clocked triple core would fair. If i see any significant gains while OCing this cpu Ill post results. I'm Prime95 testing it right now at 3.4.
