GeForce GTX 285 2GB vs GeForce GTX 470

Intro

The GeForce GTX 285 2GB comes with a GPU clock speed of 648 MHz, and the 2048 MB of GDDR3 RAM is set to run at 1242 MHz through a 512-bit bus. It also is made up of 240 SPUs, 80 Texture Address Units, and 32 ROPs.

Compare those specifications to the GeForce GTX 470, which has a core clock frequency of 607 MHz and a GDDR5 memory speed of 837 MHz. It also features a 320-bit memory bus, and makes use of a 40 nm design. It is comprised of 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
