power consumption has nothing to do with scaling, but dual cards increase heat, and that is something the 6850 is better at. Even if it has a reference cooler, which are actually pretty rare for them, it still only has a tdp of 127 watts.

460s beat down a 480, 6850s tackle the 580.

Crossfire scales better than sli, ever since the 6000 series came out.

I've been doing some more research, and it appears you're right about the 460. 6850 @ 1000mhz is roughly equal to a 460 a 815mhz, and after 1000 the 6850 scaling goes downhill, and the 460 keeps going. This however, only refers to average framerates. I speculate that the 6870 would still maintain a healthy lead in minimum rates, as it has a 10% lead over the 560 in this regard.

http://www.tomshardware.com/reviews/...p,2944-17.html

The cheapest 6850 isn't even reference cooler so that's plus in its favor also.
Dual cards increase heat but the 6850 runs hotter so it would be even more bothersome in crossfire than the 460 which runs cooler. You keep talking about non-reference AMD coolers, what about nvidia non-reference coolers...

Why are you comparing the two cards to other cards instead of each other with bench?
http://www.anandtech.com/bench/Product/314?vs=302
The 460 and 6850 are almost identical in performance at stock.

Why are you linking a review that compares scaling for the GTX 570 and HD 6950, neither of which are the cards we are talking about.

From the anandbench comparing the two cards in dual-GPU configuration directly we can see the 460 scales just as well as the 6850.

Stop grasping at straws.

I compared the same cooler on a 6850 and a 460, and I already gave you the results. The link I gave you was to show the CF improvements AMD made in their latest generation.

Although minor, the 6850 increases its lead over a 460 when the cards a paired up. So, the 6850 scales better.

The cheapest 460s are stock coolers or external exhaust from zotac/evga. The cheapest 6850 I found had a custom cooler. Regardless, even with reference cooled 6850s which almost nobody sells, the total heat produced would be much less, like 90 watts less in furmark. Even if the chips ran hotter, they'd still be within their limits and your psu would be producing less and your case would be cooler. Power consumption = Heat. All the cooler does is place it somewhere else, in the case or out.

The HD 6850 produces less heat.

Again, I don't believe anything you say because it sounds like horse****. You try to compare two completely different video cards and then make inferences on how these two cards....

If you can't provide a link to a decent review comparing temperatures then you're just blowing smoke. I could just say I did the same thing bu the 460 was cooler. Link or it didn't happen.

The benchmark clearly shows the 460 is just as fast as the 6850. Not only that, but I already provided a link detailing the efficient scaling of the 460. Unless you can provide another review that says so otherwise you're just blowing smoke.

Do you just make up numbers? There is a 40W difference in power consumption for both dual-GPU systems.

Obviously from all the reviews and links I provided the 460 is cooler, unless you can provide some contradictory reviews you're still blowing smoke. Your garbage computer review doesn't count.

The 460 not only runs cooler than the 6850, but it also overclocks better and scales better when overclocked.

GTX 560 'Non-Ti' = HD 6870,,i read the reviews,,

HD 6850 = GTX 460 1 GB

GTX 560 Ti = between HD 5870/HD 6950

I would say the 560 Ti is about the same as the 6950 (3-5% slower) before overclocking.

The 460 only runs cooler with the reference coolers. Just the fact that the gpu uses less power lets you know that with the same cooler the 6850 would be coolers. There are other variables, like the heatspreader, however the 460 uses more power and thus produces more heat.

Did you just ignore my last post? The cheapest 6850s have custom air coolers. I didn't make up numbers either, they're in the anandtech link. Where it says power consumption.

As for temps, why don't you learn physics, or find a review yourself? I'm not going to go out looking for a review of two cards with the same cooler on them, I already did it myself and just basic logic backs my statement up.

You seem really angry for no reason. Do you have a response about 6000 series CF scaling? You seem to refute all my links or just ignore them.

Want to provide some links? Your opinions are still completely worthless without any evidence behind them.

Power consumption does not mean more heat. Efficiency is a much more important contributor to excess heat. For example, a 400W Bronze PSU produces more heat than a 400W Silver PSU even though they both use the same amount of power. The FPS themselves also do not indicate effiency of power consumption because of architectural differences.

But yeah you know youre physics... eletricity = heat right?

I already linked a review praising the SLi scaling of 460s but here it is again.

Again, you don't provide any relevant links. That 570 vs 6950 scaling comparison was pretty cute though.

To OP sorry about this drag but to summarize, the 460 and 6850 are equal in performance. The 560 is faster than the 6850. The 6850 consumes slightly less power but produces more heat. The 460 overclocks better and scales better overclocked. The 560 is comparable to the 6870.

You asked to prove that 6000 series improved their scaling. I did.
I also proved 6850s scale better, which I also did.
How is that not relevant?

I wouldn't consider the 460 more efficient. Since it, and most of Nvidia's lineup, has a worse performance per watt ratio when compared to the competing AMD offering. However, I get your point point about efficiency, as it is another variable like Nvidia's choice to use a heatspreader over the chip. But, don't you think that their indicated TDPs and amps pulled are more of an idication. Afterall, one exists because of the other. To be perfectly honest, Nvidia is much more generous about their TDPs. Since a 480 does use more power than a 5970 and 590 uses more power than a 6990. Even though Nvidia claimed otherwise. This is relevant to the anandtech links I sent you.
I suppose you'll need links for that also.
http://www.tomshardware.com/reviews/...0,2898-17.html

Your link about the 460s scaling better than a 480 is pre-6850. I also showed you that although 460 scaling is good, the 6850s is better. It It was able to surpass the 460 in games which it didn't win in originally.
So our argument has been reduced to what, just heat. Not heat generated, but which runs cooler with the same cooling.

I agree with your summary minus the "producing more heat part". And of course, that "CF scales better" should be added.

I asked you to provide me evidence the 6850s scale better than 460s which you did not do at all.

Why are you linking me crap about things you're agreeing with me about. TDP =/= heat; cool whatever.

I didn't link anything that said the 460 scales better. It just says the 460 scales great. Again, you actually didn't provide any evidence the 6850 scales better than the 460.

You just make things up and I'm bored and care enough to respond.

The 6850s have a larger % framerate increase when used in crossfire compared to the 460s. That's why I am saying the 6850s scale better.

I'll check back in a few hours, if you still care enough to respond, I suspect you're getting bored of this too.
