GeForce GTX 280 vs GeForce GTX 560 Ti

Intro

The GeForce GTX 280 has a GPU core speed of 602 MHz, and the 1024 MB of GDDR3 memory runs at 1107 MHz through a 512-bit bus. It also features 240 SPUs, 80 Texture Address Units, and 32 ROPs.

Compare those specs to the GeForce GTX 560 Ti, which comes with core clock speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs along with 64 TAUs and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 can be processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 bandwidth is, the lower the potential to reach the maximum fill rate.

usted cual recomienda, para trabajar con adobe premier cs5, tengo esa duda, quiero comprar unatarjeta que me de resultavos positivos para mi trabajo, si la 280 tiene mayor cantidad de bus pero la 560ti tiene mayor cantidad de ddr5.
gracias por su aporte

Te recomiendo la GTX 560 Ti. porque? porque tiene tecnología mas nueva y es mas rápida en los programas que nombras.
