GeForce GT 430 vs Radeon HD 6450 (OEM) 1GB
Intro
The GeForce GT 430 makes use of a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this card. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which uses a 40 nm design. ATi has clocked the core speed at 750 MHz. The GDDR5 memory is set to run at a speed of 900 MHz on this particular model. It features 160 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
