ASUS Radeon HD 6950 CrossFire

[...]

Counting everything: 6950 CF has 27.5% over 5970 and 42.8% over 580[/B]

That's 27.5% more power costing 3.4% more or 42.8% more power costing 20% more. To put it into perspective, 6970 costs 23.3% more then 6950 and only brings ~12% better performance then 6950.


Unless i made some mistake, i didn't arrive @ the same conclusion as W1zzard:

You calculated that the 6950 crossfire will do 142.8% of a GTX580 and 127.5% of a HD5970, but this is considering both cards full performance, the graphs show the HD6950 performing 100%, and following your math, the GTX580 does 70% of the crossfire, and the 5970 does 78,4%

A little different, but not that much.

Correct: still doesn't add up to W1zzard's findings, but it's much closer.

So i really was making a mistake in my calculations. This means that i made the same error in this 6870 CF post.

EDIT

Only noticed ... now ... that you did the same calculations a few posts back ... that's what i get for not reading all the posts when i make my own ...

In Unigine Heaven 2.0, 6950 CF has 96.8% over 5970 and 77.9% over 580


6950 CF is $600: that's 3.4% more then a 5970 and 20% more then a 580 but how much better then a 5970 and 580 is it? Shall we add up?

Not counting the 3DMark benches AND Unigine bench: 6950 CF has 26.1% over 5970 and 41.5% over 580

Not counting 3DMark benches only: 6950 CF has 38.8% over 5970 and 43.9% over 580

Counting everything: 6950 CF has 27.5% over 5970 and 42.8% over 580

That's 27.5% more power costing 3.4% more or 42.8% more power costing 20% more. To put it into perspective, 6970 costs 23.3% more then 6950 and only brings ~12% better performance then 6950.

Judging from this, the 6990 will totally destroy 5970 and 580: i wonder how it will stand against the dual GPU card nVidia is supposedly working on.

Thanks for the write up, couldnt of said it any better.. Antiless vs 590gtx, game on it seems!

how do you expect nvidia to do a dual gpu card if their tdp is over 9000? ._.

I'd really like to get another 6950 to CF. These results are great!

edit: just ordered a new gigabyte 6950 to CF. hope my psu can handle it

In the meantime, we know that the first batch of HD6950's were in fact down-BIOS'ed 6970's, so maybe that's why they scaled so good in CFX...
