1.Less cores means less power, and less heat. This means you should be able to reach higher frequencies with an equal cooler.
2.Most games don't use more then 4 cores, the only one i can think of off the top of my head is bf3, in games that use 4 cores, the fx-81xx or fx-61xx may perform better because it has 4 cores it can dedicate specifically to the game, and 2-4 extras for idle stuff. But for the most part, the fx-4100 will perform pretty equally with it's higher core counterparts at equal clocks.
So in my opinion, in most cases the fx-4100 overclocked by one with some knowledge will outperform the fx-81xx in gaming due to the fact you can reach higher clockspeeds (in most cases, not all chips are the same of course smile.gif )

Well I can disable two or four cores. You think it will create less heat and perform better ?

it was an analogy,and bulldozer is like a rotory rather than a straight six.

If you can get higher clocks after you disable those cores, and the cores that were disabled weren't being used, then yes you would get better performance.

LOL,kind of,though there's still a tiny bit of CPU analogy in it somewhere.

Like a super Bulldozer with a ton of cores? If PHII is a piston engine maybe a V6, then BD is a rotary,SB is a high HP 4cyl.

In the rotary piston type of engine the crankcase and cylinders rotate around a fixed crankshaft with the pistons attached. The propeller is attached to the crankcase, not the crankshaft with a rotary piston engine. These were used during WW1, and phased out soon after in preference for Radial Piston engines. In a Radial Piston engine the crankshaft spins inside of the crankcase with the pistons attached to it and the propeller is attached to the crankshaft. These are what you are seeing when you look at a B-17 or Corsair fighter.
@ HMG : I am aware that true rotary engines exist and some have been used in aircraft. My dad is a pilot and a general aviation buff, I first saw rotary engined planes in the 80s at the OshKosh airshow.
I know that rotary engines were popular in the 80's but never heard of them being used in planes.

@ BF3Player: I am interested in seeing your experiments, if you do them. I know that this has been done, although I don't know exactly how much farther you can crank up 4 cores rather than 8. I think the best way is to turn off every other core- leaving each active core with the whole resources of each module.

@ HMG: They don't call the it the EAA OshKosh Airventure for nothing. ( EAA = Experimental Aircraft Association) Biggest airshow in the world- BTW. Very impressive.

So enable 1-2 and 5-6 cores? Not 1,2,3,4 ?

From what I know you would run cores 0,2,4,6 or 1,3,5,7 to have one core on in each of the four modules. 0123 would give you 2 modules, each with 2 cores per module, same as using 4567. I used the 0,1,2,3,4,5,6,7 system that the UEFI or BIOS uses as enumeration of cores for clarity.

I will do this expeirment and give you some stats. Should I leave my vcore @ 1.36v ?
