GeForce GTX 280 vs GeForce GTX 560 Ti

Intro

The GeForce GTX 280 features a core clock frequency of 602 MHz and a GDDR3 memory speed of 1107 MHz. It also features a 512-bit bus, and makes use of a 65 nm design. It is made up of 240 SPUs, 80 TAUs, and 32 Raster Operation Units.

Compare all that to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has clocked the core speed at 822 MHz. The GDDR5 RAM works at a frequency of 1002 MHz on this model. It features 384 SPUs along with 64 Texture Address Units and 32 ROPs.

The GeForce GTX 280 should in theory perform a small bit faster than the GeForce GTX 560 Ti overall. (explain)

GeForce GTX 280 141696 MB/sec
GeForce GTX 560 Ti 128256 MB/sec
Difference: 13440 (10%)

Texel Rate

The GeForce GTX 560 Ti will be a little bit (about 9%) more effective at AF than the GeForce GTX 280. (explain)

GeForce GTX 560 Ti 52608 Mtexels/sec
GeForce GTX 280 48160 Mtexels/sec
Difference: 4448 (9%)

Pixel Rate

The GeForce GTX 560 Ti is much (more or less 37%) more effective at AA than the GeForce GTX 280, and will be capable of handling higher screen resolutions without slowing down too much. (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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to 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.
