GeForce GT 430 vs Radeon HD 4670 1GB
Intro
The GeForce GT 430 features a clock speed of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 16 Texture Address Units, and 4 ROPs.Compare those specs to the Radeon HD 4670 1GB, which features a core clock frequency of 750 MHz and a GDDR4/GDDR3/DDR3/DDR2 memory frequency of 1100 MHz. It also uses a 128-bit bus, and makes use of a 55 nm design. It is made up of 320(64x5) SPUs, 32 Texture Address Units, and 8 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one 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 calculated by multiplying the number of Raster Operations Pipelines 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 fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
