GeForce GTX 460 2GB vs Radeon HD 5970

Intro

The GeForce GTX 460 2GB makes use of a 40 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR5 memory runs at a speed of 900 MHz on this particular model. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.

Compare those specs to the Radeon HD 5970, which has a clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It is comprised of 1600 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

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

Texel Rate

The Radeon HD 5970 will be quite a bit (about 514%) better 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 a high screen resolution is important to you, then the Radeon HD 5970 is the winner, by far. (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 data (in units of megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, 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 worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the 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 write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum 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
