GeForce GTX 580 3GB vs Radeon HD 6970

Intro

The GeForce GTX 580 3GB features core clock speeds of 772 MHz on the GPU, and 1002 MHz on the 3072 MB of GDDR5 memory. It features 512 SPUs as well as 64 Texture Address Units and 48 ROPs.

Compare those specs to the Radeon HD 6970, which makes use of a 40 nm design. AMD has clocked the core frequency at 880 MHz. The GDDR5 memory is set to run at a frequency of 1375 MHz on this model. It features 1536 SPUs along with 96 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.

This my dream 🙂

GOOOOD fight

Janus says:

Does this site lean to Nvidia side on those power graps or is there just something simply wrong with the one writing em?

Power consumption numbers for gtx 500 series are fucked up

admin says:

@Janus: I got the power numbers from Wikipedia. They should be the max power draw under load. Unless Wikipedia got it wrong... which is always possible.

I just checked TechARP.com's list, and the numbers are the same there as well.

How are they wrong?

Bjørn says:

No, they're wrong, 580 1.5GB goes well above 300W when under load.

admin says:

Do you have a source link for that so I can get the exact numbers?

huh? says:

what kind of speculative, unsubstantiated garbage is this? How do you get away with posting crap like this and still manage to have any readers?

admin says:

@huh?: Do you have a correction to make to the info here? We got our information either from Wikipedia or from TechARP. All we did with it is some calculations and made pretty graphs. If our original information is wrong, then the pretty graphs will be wrong too. I have made some corrections to a few things recently that turned out were input wrong... annoying, but it happens. Power consumption is max TDP, I edited the titles to make that more clear.

k says:

admin, don't mind these ppl. Although here it says the power draw is pretty different: http://www.anandtech.com/bench/Product/305?vs=292
Btw, this site is very nice, so thanks! I hope you will support CPU comparison, too!

admin says:

Thanks k 🙂 We do plan to add CPU comparisons in the future actually.

That Anandtech comparison has the power usage as total system power draw (as in, not just the card alone). I think the sources we use are probably the card alone. Though I'm not sure how they would go about measuring that... but anyway, here's Wikipedia's source for the power numbers: http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_580/3.html

James says:

Of course those stats are pretty close to the real deal except for different manufacturers like Evga,xfx,Sapphire,HIS all change each card to their own liking but being rude is un called for.

gangsta fred says:

you are all a bunch of whores

Sid says:

Come on,"gangsta fred",forums and communities only exist because of arguing over such trivial matters.Besides,the only right result is the one you measure yourself.However,nobody has the money to buy all of that,and we're forced to believe others.

M0HAX says:

Good job!

Bruder95 says:

harter kampf trotzdem gtx580 bisschen besser

Vemri says:

i was a "red" side big fans. but don't know some how i found that physx in "green" has more secret weapon in its "pocket".
and here am i using my 580 lightening, and it runs very perfect for kicking all latest game ass.

Gareth says:

@Huh you are what people call a doos. Thanks for the input. The website clearly states more or less and that the performance may vary in real life. I have been using this website for years. Thanks!!!
