AMD 125w vs 140w

Really? I would have thought as the 140w having a higher starting point that would be it?

also for would the 125w be better for gaming?
 
140W tdp means the cpu actually can put out 140W of heat, as you overclock this becomes more and more. Obviously a cpu with a lower dissapation of the same generation might well overclock more as it had more headroom. It may dissapate less heat due to die shrinks, better/revised process or lowered vcore (hence, usually a better core, though not always) or all of the above. There obviously is another reason that 965 125w is 125w, as the extra 100Mhz of the 970 will not likely add 15w, thus even at 3.5Ghz, the 965 should be cooler.

The 140W will kick out more heat as a result of the extra 100mhz, higher TDP = better cooling required.

It doesn't necessarily mean one will overclock better though, the 970BE is probably a higher quality chip in this case.

But in cases like the 1055T 95W v 125W the 95W is actually a much higher quality chip and as a result runs on considerably less voltage and has more headroom to overclock.

I know nothing of AMD cpus, but the 100MHz is not the reason for the higher TDP, there is a 970 125W edition as well, looking at google it looks to be a slightly revised core. According to Extreme psu calc, a BE 965 125w edition would dissipate 129w at 3.5GHz assuming stock voltage, it would take up to 3.8Ghz to start throwing out 140W.

I first thought that this might relate to the amount of power required for the cpu and thus make it more powerful.

Been out of the game for quite a while but starting to get my head around things again.

thanks again for your explainations.
 
Yep, have seen a few competitors call it a 140W as well, but all seem to be C3, some forums have said its 125W quoted direct from AMD.
 
Save yourself £15 and get the 965. Clocks very easily. Even if you just wanted that extra 100 ghz you could just increase the mutli a notch and you probably wouldn't need to touch the volts.

I've clocked my 965 from 3.4 to 3.8 by changing the multi from 17 to 19 and increasing the volts form 1.375 to 1.425. Hasn't hit my temps much save for literally 2 dgerees.

What I will sya though is the stock hsf is noisey and hot so invets in a decent cooler.
