Radeon HD 6450 (OEM) vs Radeon HD 6450 (OEM) 1GB
Intro
The Radeon HD 6450 (OEM) comes with a core clock frequency of 625 MHz and a GDDR3 memory speed of 800 MHz. It also makes use of a 64-bit memory bus, and uses a 40 nm design. It is made up of 160 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which comes with a clock speed of 750 MHz and a GDDR5 memory speed of 900 MHz. It also features a 64-bit bus, and uses a 40 nm design. It features 160 SPUs, 8 Texture Address Units, and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must 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 can be processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 ability to reach the maximum fill rate.
