GeForce 8500 GT vs GeForce GT 430 1GB
Intro
The GeForce 8500 GT comes with a clock frequency of 450 MHz and a DDR2 memory speed of 400 MHz. It also makes use of a 128-bit memory bus, and uses a 80 nm design. It is comprised of 16 SPUs, 8 TAUs, and 4 ROPs.Compare those specs to the GeForce GT 430 1GB, which has GPU core speed of 700 MHz, and 1024 MB of GDDR3 memory running at 900 MHz through a 128-bit bus. It also is made up of 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core clock 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 a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
