GeForce GTX 280 vs GeForce GTX 560 Ti

Intro

The GeForce GTX 280 comes with clock speeds of 602 MHz on the GPU, and 1107 MHz on the 1024 MB of GDDR3 memory. It features 240 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

Compare those specifications 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 RAM. It features 384 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

GeForce GTX 280 48160 Mtexels/sec
Difference: 4448 (9%)

Pixel Rate

The GeForce GTX 560 Ti will be much (more or less 37%) more effective at full screen anti-aliasing than the GeForce GTX 280, and should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 560 Ti 26304 Mpixels/sec
GeForce GTX 280 19264 Mpixels/sec
Difference: 7040 (37%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max 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
