GeForce GT 320 vs Radeon HD 5750 1GB
Intro
The GeForce GT 320 features a clock frequency of 540 MHz and a GDDR3 memory speed of 790 MHz. It also features a 128-bit bus, and uses a 40 nm design. It features 72 SPUs, 24 Texture Address Units, and 8 ROPs.Compare those specifications to the Radeon HD 5750 1GB, which makes use of a 40 nm design. AMD has clocked the core speed at 700 MHz. The GDDR5 RAM is set to run at a frequency of 1150 MHz on this card. It features 720(144x5) SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, 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, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
