Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

I agree. But there is an error. The HD 5970 texel rate 2 times lower - 116 MTexels.
I have a HD 5970 still is good! I wont replace it never! but maybe I will get a GTX 590 3GB when prices will drop
7970 was owned by our old 5970. they created a monster only once
MAN!! What the hell is this??
5970 faster than 7970??
Are u freakin' kiddin' me?
holy ass! the NEW 7970 got its ass handed to it by its older brother, the good ole' 5970.
Apparently none of you realize the 5970 is a Single Card Dual GPU while the 7970 is a single card single GPU. That's like comparing apples and two apples to see which has more food on it.
@Idiot Police but still u cant change the fact that 5970 is beast for more than 2 years old gfx card
They both only take up 1 slot, and both cost around the same even today.. 5970 was my purchase when it was new, and if i could take it all back and buy the 7970, i wouldn't. They're gonna have to create a new mold for the future.. they sure as hell broke it after the 5970.
you all will never andrestanding the ultimate power of great 5970, i hold this card for nearly 4 years and yet show no sign to being retreated.i wish i could have had another last 5970 to crossfired with my own one but its better to keep waiting for 8000 or maybe 9000 series.

The Upcomming 7990 is rumored to surpass them all. including Nvidia's beast the gtx 690
I hope you know that the specifications for the 5970 are wrong on this site. For some reason they're tripled, or doubled... I don't know what... someone got the specs wrong. The 6970s and 6980s easily surpass this card by a huge margin. This is an error... go check the specs on the AMD website yourself.

I have the 5970 and confirm that it's a piece of shit.
I can barely play AC3 on 15-20 fps in boston and shit even lags on d3 with 4 player games.
The only thing it does right is shooters, which I don't even fucking play.
a placa tenho um crossfire 5970 e até hoje não tem nada para bater. nem uma gtx690 que eu também tenho e não chega nem nos pés do meu crossfire.
io ho 2 5970 tedeschi di merda e vi dico che sono melgio le 5970 crucchi di merda .
According to AMD site only the texel and pixel rate has been doubled.
Part from that fact 5970 still smashes the 7970 in pixel rate by far,
which considering the age of the 5970 is bloody amazing.
At this point I'd go for 5970, just because it's a LEGEND
Just so you all know the information listed for the HD5970 is completely wrong.
Its good, not this good.
