[H] 660 Ti OC vs. 670 OC vs. 7950 OC - Page 8

post #71 of 363
Finally, a review for those that actually thought the 660TI was better value than the 7950. Now those naysayers can go away tongue.gif

I <3 my 7950. At 1.2ghz, I got high-end performance for mid-range price. Can't beat that thumb.gif

7950's are looking good, especially once the nice ones like the WF or TF get down to sub $300 biggrin.gif

You are right on the money with that remark. It would probably take two years of heavy gaming OC'd to come anywhere near half the price difference.

But here is another angle. I have a fairly new Corsair ax750. I could run two 670 FTW in sli OC'd without needing to upgrade psu.

Chances are I wouldn't be able to do that with two 7950 with a decent OC.

Face it. The 7950 and GTX 670 compete, and the 7970 and the GTX680 compete. In both cases, the AMD cards are better once you get into higher resolution (particularly multimonitor) and higher memory-bus bandwith gameplay, and in both cases the AMD cards are cheaper than their nVidia counterpoint.

Truth +1 my good sir

My 670 pcb has a much nicer black color than AMD. Deeper, richer and shinier plastic. It's even more smudge proof. thumb.gif

anndddd my has heat pipes....5 of them!!


speaking of which.. OFF TOPIC:::;;

I was looking at the pic to make sure i have 5 heatpipes as my card is i UPS hands right now in Baldwin Park Cali, and i saw that it went up in price

::http://www.newegg.com/Product/Product.aspx?Item=N82E16814102995

I purchased this card on sunday for $329 and now its gone back up to $350 lol

Glad i snagged it cheaper!!

EDIT::

wait i linked the wrong card lol thats the non OC or lighter OC card.

this is the one i got lol

Looks great for the 7950. I might just have to pick one up to replace my dead 5770...

Did it even say how many Volts? All cards OC differently. I can do 1.2Ghz with stock voltage. Some need less, some need more.
If HD 7950 does use more power OCed then thats that. Calculate the Hours you have the system under full 3D load and you will find out you don't really save much.

This.

Honestly, if you can power three 7950s with your current setup according to Outervision's PSU calculator I think you can power two overvolted 7950s. I still don't see how this is an issue anyway, considering that if you have say a 600W PSU that might be able to handle OC'd SLI 670s but not OC'd CFX 7950s, the difference between the two cards in total is probably ~$125 whereas the cost of a high quality 750W PSU is around $90. That $35 would take a pretty long time to add up on the power bill.

The other point is that because kepler is voltage locked on most cards, you will never truly see the overclocked power consumption of kepler unless you have a voltage unlocked card. What happens with kepler is that it throttles after 10-15 minutes of being overclocked - when the temp is too high or the power % is too high. I can't tell you the number of times i've had a ref 680 throttle after 5-10 minutes of overclocking, 7970 does not do that.

Also, if you want to see the true power consumption of kepler look at the anandtech review of the GTX 680 classified by EVGA. When it is over volted it uses more power than any AMD card on the market, by a lot.. What you are seeing - again - is the voltage locked nature of kepler (in combination with kepler throttling) hides the true power consumption.

48510.png

425 Watts. Yeah.. So thats what you get when kepler is over volted, which is higher than what the 7970 gets when overvolted. Voltage lock hides this very well though I guess.

Keep in mind that 99% of kepler cards are locked at 1175mV. This hides true power consumption and throttles when the OC goes awry, while AMD cards do not do this and are not locked (thus use more power)

How am I making a false statement? You linked an old review of a 7950 that was overvolted. At this point in time a 7950 does not need to be overvolted to keep up with a 670. Therefore a 7950 will not use more voltage to "keep up" as you put it.

A $300 7950 is awesome, good job AMD. It's incredible how much of a performance gain the 7950/7970 got with Catalyst 12.7.
