Radeon HD 5750 1GB vs Radeon HD 6450 (OEM)
Intro
The Radeon HD 5750 1GB comes with a GPU clock speed of 700 MHz, and the 1024 MB of GDDR5 memory runs at 1150 MHz through a 128-bit bus. It also features 720(144x5) Stream Processors, 36 TAUs, and 16 ROPs.Compare those specs to the Radeon HD 6450 (OEM), which comes with a GPU core clock speed of 625 MHz, and 512 MB of GDDR3 memory running at 800 MHz through a 64-bit bus. It also is comprised of 160 Stream Processors, 8 TAUs, and 4 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
