GeForce GTX 460 2GB vs Radeon HD 5970

Intro

The GeForce GTX 460 2GB has a core clock speed of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

Compare all that to the Radeon HD 5970, which features a GPU core clock speed of 725 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also is comprised of 1600 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

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 information (in units of MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also 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 potential to reach 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
