GeForce 9500 GT 1GB GDDR3 vs GeForce GT 430 1GB

Intro

The GeForce 9500 GT 1GB GDDR3 features a GPU core speed of 550 MHz, and the 1024 MB of GDDR3 RAM is set to run at 800 MHz through a 128-bit bus. It also features 32 SPUs, 16 TAUs, and 8 ROPs.

Compare that to the GeForce GT 430 1GB, which uses a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this specific card. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
