GeForce GTX 285 2GB vs GeForce GTX 570

Intro

The GeForce GTX 285 2GB has a GPU core speed of 648 MHz, and the 2048 MB of GDDR3 memory runs at 1242 MHz through a 512-bit bus. It also is comprised of 240 SPUs, 80 TAUs, and 32 ROPs.

Compare those specifications to the GeForce GTX 570, which has a core clock speed of 732 MHz and a GDDR5 memory frequency of 950 MHz. It also makes use of a 320-bit memory bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 60 TAUs, and 40 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 memory bandwidth is, the lower the ability to get to the maximum fill rate.
