# 7950 or gtx 670? - Page 12

Quote:

Look dude, your math is wrong from when you said there was a \$180 difference in operating the two cards over the course of a year. Here's how:
265w = 0.265kw. (0.265kw) * (\$0.15 kw-hr) * (5hr/day) * (365 days) = \$72.54 To power the card for a whole year.
369w = 0.369kw. (0.369kw ) * (\$0.15 kw-hr) * (5hr/day) * (365 days) = \$108.40 To power the card for a whole year.
That is NOT \$180 difference per year, that's only \$35 difference per year. % difference aside, there's really hardly any monetary difference over the course of a power bill for an entire year for a household.

You're right, i made a mistake

This is exactly why i posted all my information rather than spouting numbers so other people could review it and check it for fallacies. I'll go edit all my previous posts to reflect this

Edit: I blame this calculator, it's totally inaccurate and i shouldn't have trusted it. I should have just done the calculation myself

An OC'd 7970 (1,25 - 1,3GHz) will crush your 1,3 GHz 670 in most games, thats another fact.
Keplers OC scaling is simply terrible (possibly bandwidth limited).
Stop getting upset just because most in here are favoring the 7950.
Oh and I'm not bashing Kepler in any way, im even an nVidia fan. Im simply being objective. Judging from a performance standpoint when overclocked to the max AMD has the edge. (Stock for stock its nVidia)
I still prefer Kepler as an overall package though (performance, heat, consumption, noise etc.)

I think my message was lost in my rant i was kinda aggravated that i went through 5 or 6 pages of 7950 is awesome here , 670 is awesome here , well no jo blo says 7950 does this if you do this , oh yeah well only because 670 turbo boost blah blah blah

im just saying , i had a 7970 , amds breakthrough chip , i paid \$599 a couple of months ago for the XFX DD , and it didnt blow my freaking mind. I love an underdog , i love em , i ran AMD cpus all the way from the original k6 to athlon 64 , they lost me when the core duo came out. Then nvidia came out with the 680 , \$499 when 7970's were still that or more. I waited. Then for \$399 nvidia releases the 670 , it performs 90%+ of the 680 , on par with it and the 7970 in alot of things with an oc. For what i consider a great value. AMD has always represented value to me , until now. Nvidia has beat AMD at their own game , VALUE. Someone has to agree with me on this .

XFX DD is the worst non-reference ever. No good colling in vram no good overclock. My best friend took one and he insta-give it back. You should give it back and take sapphire,asus or msi

mine did 1250mhz overclock !!! lol , its mem didnt oc for crap , but id consider 1250mhz successful . I sent it back almost a month ago lol

none of this matters until AMD enables turbo boost on the 7 series . all post are irrelevant until both companies disable all their technological innovations . Disable T&L and it will be more fair too , maybe disable the awesome power state in the 7XXX cards where it turns off when not in use. No more Direct X anything. Lets just run quake 3 benches. /s

When you have a crap vram cool your card performance drops really fast. From what a search back in january when i first buy my sapphire the XFX DD had the worst cooling solution. Vram temps easily hits 110 with XFX DD which is really bad

Well, Eric, I see where you got the numbers, but I just think that when it's known that the Perf per Watt between 7950 and 670 is only 2% different at stock clocks/volts, using like 15 benchmarks ... it's gonna be a tough sell to convince anyone that the 670 is 28% 'more efficient' when OC'd ... based on one benchmark

I suspect what happened is that [H] must've pushed voltage way up into the 'diminishing returns' range in terms of clock increases on the 7950 ... which just isn't possible on the 670.

The 'fair' way to do the OC'd efficiency calculation would be to look at the % delta between the 670's stock voltage and the 670's OC'd voltage, apply an equal, additional % delta to the voltage of the 7950, OC the 7950 as much as will be allowed from the voltage increase, and THEN re-calculate performance per watt.

@sugarhell , do you mean VRM or Vram ? you say vram but i always suspected the vrm wasnt properly cooled because my oc would take a dump with strenuous gaming.

There's really no need for people to call each other trolls here, first of all. Please do not do so again, anyone on this thread. We're all just trying to be heard, give our take, educate one another, etc. I don't see anyone here 'trolling'.

Secondly ... in reality there's nothing wrong with Kepler's scaling at all ... what's a problem though is a lot people (including reviewers) calculating it ENTIRELY WRONG.

It's fair to say that Tahiti (esp. Tahiti Pro) ultimately has more OC'ing headroom in terms of % clock delta, and hence the % fps increase from that delta ... however, the OC scaling ... e.g. the ratio (% fsp increase / % clock increase) is probably very similar. My guess is that when properly calculated, Kepler would show slightly better scaling. I guess that purely because Fermi's utterly blew the 5/6xxx series out of the water in this regard

I'm glad they ended up doing that. Maybe my analysis inspired them as i posted it up a few hours before them? Doubt it, but i can still flatter myself . It also shows how close my estimations were compared to their empirical data. I'm kind of disappointed though that they didn't compare power usage and noise levels too at both stock and overclocked speeds. They also didn't take into account the power cost when comparing prices as the 7950 at \$379 is the exact same price as a 670 at \$400 after a year.

If you are not one to overclock, it is clear the GTX 670 is the better value even when compared to AMD's \$449 HD 7970. The \$399 GTX 670 can deliver a similar experience for less money. When compare the price compatible GeForce GTX 670 to the Radeon HD 7950, the value delta is tremendous; it is simply an embarrassing scenario for the Radeon HD 7950. The GeForce GTX 670 clearly offers much better gaming performance at the same price. At the current prices the Radeon HD 7950 cannot compete in the market.

I think that's a little harsh, but ... funny. The 7950 sample didn't seem to be a very good OC'er ... here's the clocks they used:
Quote:
For the GeForce GTX 670 we found the highest stable overclock to be 1234MHz core frequency and 6.4GHz memory.

For the GeForce GTX 680 we found the highest stable overclock to be 1228MHz core frequency and 7GHz memory.

For the AMD Radeon HD 7950 we found the highest stable overclock to be 1050MHz and 6GHz memory.

For the AMD Radeon HD 7970 we found the highest stable overclock to be 1260MHz and 6.9GHz memory.

Although their 670 isn't the greatest either, I suspect its a lot closer to 'average' 670 OC's in terms of % delta than their 7950 sample was. Still, the 7950 OC gets dominated pretty hard in nearly every test vs. the OC'd 670.

It just needs to drop to like \$360, then it'll be awesome again
