GeForce GTX 580 3GB vs Radeon HD 5970


The GeForce GTX 580 3GB uses a 40 nm design. nVidia has clocked the core frequency at 772 MHz. The GDDR5 memory is set to run at a speed of 1002 MHz on this particular model. It features 512 SPUs along with 64 TAUs and 48 Rasterization Operator Units.

Compare those specs to the Radeon HD 5970, which has GPU core speed of 725 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also features 1600 Stream Processors, 160 Texture Address Units, and 64 ROPs.

The Radeon HD 5970 will be a lot (about 370%) better at anisotropic filtering than the GeForce GTX 580 3GB. (explain)

Radeon HD 5970 232000 Mtexels/sec
GeForce GTX 580 3GB 49408 Mtexels/sec
Difference: 182592 (370%)

Pixel Rate

The Radeon HD 5970 should be much (about 150%) faster with regards to anti-aliasing than the GeForce GTX 580 3GB, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon HD 5970 92800 Mpixels/sec
GeForce GTX 580 3GB 37056 Mpixels/sec
Difference: 55744 (150%)

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 max amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are 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 the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.

kostas says:

it should be 50 percent better.......ambelivible

Dave says:

These are theoretical numbers. The 3gb 580 would perform much closer to that of the 5970 than this.

hakeeme says:

i dont believe this

nic says:

yes i would like to see the 5970 4gb on this website, also the upcoming classified 580 3gb.

LOL says:

Bunch of morons!!! Yeah theoretical and actual makes a huge diff!!! Dumb@sses!!

shooter says:

Hate to disappoint all the nVidia fanboys, but the GTX580 Classified, FTW or whatever else nVidia is trying to release these days will still get spanked by the ATI 5970. Better take a closer look at those specs of the's a refresher 1600 SPUs as well as 160 TAUs and 64 ROPs GTX580 doesn't even come close so $499.99 and still getting spanked by the ATI 5970 and I have two of these puppies in crossfireX want to see those real world benchmarks against your Tri-SLI GTX580's?
