7850 oced vs 660 oced

Yes voltage is to do with heat. But anything which has energy pushed into it generates something not wanted. Like heat, noise, light etc.

I prolly didn't word what I last said correctly but your trampling on your own toes as this point.
 
Heat and voltage will be a limiting factor, to much Oc (volt) will make more heat as its pushed at a higher rate to feed the chips/components with more power (making them run beyond there normal specs)

Check my sig, if i wanted more grunt from the GPU i would have to adjust my volts as that Oc im running is on stock volts.(stock for my card is 860 core with 1200 mem)

If i gave it more volts i could push it higher, now pushing higher would also mean my temps would run a lot higher than what i get now.
 
Lets reverse the question so we can use it with your example.

If you cooled your GPU to -100 for example (I am sure we have some hardcore overclockers in the forum) would you need the same/less/ or more voltage to run at the same speed?
 
That don't make any sense at all.

"If you cooled your GPU to -100 for example (I am sure we have some hardcore overclockers in the forum) would you need the same/less/ or more voltage to run at the same speed? "

Sorry ive read it over an over an its jsut making no sense to me or im missing some thing.

People go water cooled so they can clock there hardware higher (volts an timing) this in turn will make the hardware hotter.

Now this is why people use better coolers or water coolers nearly any Oc will result in temp rising (an the temps will differ depending on how much Oc it has an what cooling) as the item is running beyond its stock configuration.
 
The 660 bottlenecks with the overclock unfortunately. The 7850 does not suffer with this issue. The 7850 is a hard one to beat. I have mine at 1200 core and 1450 memory.
 
Lets try this then.
If you apply some sort of extreme cooling to your GPU, will you be able to run at the same/lower/higher frequency with the same vcore?

It all depends if it requires better cooling due to temps or your just an enthusiast who likes to push there rig to the extreme bench marks.

If your getting low temps on a mild Oc that your happy with then better cooling isn't needed, like mine has increased 5-8 on stock volts from 860-1050 so there's no reason to get a better cooler.

If you've Oc high as possible an stable which 99% of the time needs a volt adjustment then you would be better off getting a better cooler to stop it burning out chips.

But it also depends on what cooler your using.

I totally agree about the whole oc hype. If you cannot notice the difference without using a fps counter don't bother.
I also think that the average oc for 7850 is around 1100 and anything over 1200 is just asking for trouble as it will certainly involve increasing voltages.

I have 1200 at stock voltage.
 

It doesn't require increased voltages.

Taking the 7850 to 1200 is a 39.5% increase in clock speed.
Taking the 660 to 1100 is a 12.2% increase, but watch out for the bottleneck with the memory with this card.

This is still going on? I need more coffee before i even attempt to catch up, don't want to miss any chuckles.
 
Ok lets make it simple for you.
If the fan of your card fails will you run into any problems or not? Remember you are still using default volts - no increases, nothing.

Voltage can determine how far you can overclock a GPU, but all GPUs have a limit in what voltage they can take, regardless of the temperature, to the point where the chip will completely degrade regardless.

They are however large increases in volts.

Increasing the voltage means more heat, and more heat gets in the way of overclocking. Less heat and more voltage generally will mean better overclocks.

It's really simple stuff, why are you trying to overcomplicate it? It looks like you're doing it on purpose.

As for it being pointless, well, not really. My 7950s are overclocked about 62% higher than reference 7950 clock speeds, which makes for a massive increase in performance.
 
The 7850 overclocks quite a bit better than the 660 and in turn becomes faster. A 660 was only a good buy when they were down at £150 - £160 for a while, now they cost the same as a 7870 at £179 which is significantly better.

Not to mention there is a lot of B grade 7850's for sale at £130, considerably cheaper than the retail/GTX660.

However a 7870 is apparently a poor mans 7950, so get one of those, clock it and you have pretty much a 7950. You can do the same with the 7850 but I beleive the 7870 runs of the same core chip as the 7950 while the 7850 doesen't :)
