Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 2GB 160 Watts
Radeon HD 5970 294 Watts
Difference: 134 Watts (84%)

Memory Bandwidth

In theory, the Radeon HD 5970 should perform quite a bit faster than the GeForce GTX 460 2GB in general. (explain)

Radeon HD 5970 256000 MB/sec
GeForce GTX 460 2GB 115200 MB/sec
Difference: 140800 (122%)

Texel Rate

The Radeon HD 5970 is much (more or less 514%) more effective at anisotropic filtering than the GeForce GTX 460 2GB. (explain)

Radeon HD 5970 232000 Mtexels/sec
GeForce GTX 460 2GB 37800 Mtexels/sec
Difference: 194200 (514%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5970 is a better choice, by a large margin. (explain)

Radeon HD 5970 92800 Mpixels/sec
GeForce GTX 460 2GB 21600 Mpixels/sec
Difference: 71200 (330%)

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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 outputting the pixels (image) to the screen. The actual pixel fill 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 get to the max fill rate.

hola sres, de esta pagina, les escribo xke hace 1 año ke entre en el mundo de las placas de video y a jugar un poco mas, y estoy x cambiar mi placa y hace 2 dias conoci la ati 5970, y entre aqui a su pagina que desde hace ya un tiempo siempre la uso para compara placas, y al comparar esta placa la ati 5970 con cualquier otra placa ya sea de geforce o de ati ej la titan o la 7970 o la ultima belleza de ati la 7990.y me doy que con los datos de los resultados ke proveen, la ati 5970 es la placa mas poderosa ke existe eso es asi? o hay algun dato mal cargado y x eso da que supera a absolutamente a todas! espero ke m puedan sacar de la duda y a la vez a ayudarm a elegir mi proxima placa de video. desd ya muchas gracias
