GeForce GTX 285 2GB vs GeForce GTX 560 Ti 448

Intro

The GeForce GTX 285 2GB uses a 55 nm design. nVidia has set the core frequency at 648 MHz. The GDDR3 memory works at a frequency of 1242 MHz on this particular model. It features 240 SPUs along with 80 Texture Address Units and 32 ROPs.

Compare all that to the GeForce GTX 560 Ti 448, which has core clock speeds of 732 MHz on the GPU, and 900 MHz on the 1280 MB of GDDR5 memory. It features 448 SPUs along with 56 TAUs and 40 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, 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 maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
