GeForce GTX 285 2GB vs GeForce GTX 460 SE
Intro
The GeForce GTX 285 2GB makes use of a 55 nm design. nVidia has clocked the core frequency at 648 MHz. The GDDR3 memory runs at a frequency of 1242 MHz on this specific card. It features 240 SPUs as well as 80 Texture Address Units and 32 ROPs.Compare those specs to the GeForce GTX 460 SE, which comes with core clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 288 SPUs as well as 48 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
