GeForce GTX 285 1GB vs GeForce GTX 560

Intro

The GeForce GTX 285 1GB makes use of a 55 nm design. nVidia has set the core speed at 648 MHz. The GDDR3 memory works at a frequency of 1242 MHz on this card. It features 240 SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 560, which features GPU clock speed of 810 MHz, and 1024 MB of GDDR5 RAM running at 1001 MHz through a 256-bit bus. It also features 336 Stream Processors, 56 TAUs, and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total 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 chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
