GeForce 9500 GT DDR2 vs GeForce GT 430

Intro

The GeForce 9500 GT DDR2 has a GPU core clock speed of 550 MHz, and the 256 MB of DDR2 RAM runs at 500 MHz through a 128-bit bus. It also features 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare those specs to the GeForce GT 430, which has a core clock speed of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It features 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better 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 that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
