Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4550 256MB 25 Watts
Radeon HD 6450 (OEM) 31 Watts
Difference: 6 Watts (24%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon HD 6450 (OEM) will be a bit (approximately 4%) better at texture filtering than the Radeon HD 4550 256MB. (explain)

Radeon HD 6450 (OEM) 5000 Mtexels/sec
Radeon HD 4550 256MB 4800 Mtexels/sec
Difference: 200 (4%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 6450 (OEM) is superior to the Radeon HD 4550 256MB, but it probably won't make a huge difference. (explain)

Radeon HD 6450 (OEM) 2500 Mpixels/sec
Radeon HD 4550 256MB 2400 Mpixels/sec
Difference: 100 (4%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of 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 clock speed of the chip. The higher this number, 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 maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
