GeForce GT 430 vs GeForce GTX 260

Intro

The GeForce GT 430 has a GPU core speed of 700 MHz, and the 512 MB of GDDR3 memory is set to run at 900 MHz through a 128-bit bus. It also features 96 Stream Processors, 16 Texture Address Units, and 4 ROPs.

Compare those specifications to the GeForce GTX 260, which features a core clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also features a 448-bit memory bus, and uses a 65 nm design. It features 192 SPUs, 64 Texture Address Units, and 28 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
