Compare any two graphics cards:
Radeon HD 5550 vs Radeon HD 6450 (OEM)
IntroThe Radeon HD 5550 features core clock speeds of 550 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 memory. It features 320(64x5) SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 6450 (OEM), which has a GPU core clock speed of 625 MHz, and 512 MB of GDDR3 memory set to run at 800 MHz through a 64-bit bus. It also features 160 SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have the exact same memory bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe Radeon HD 5550 is a lot (about 76%) more effective at AF than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe Radeon HD 5550 should be much (approximately 76%) more effective at anti-aliasing than the Radeon HD 6450 (OEM), and will be able to handle higher resolutions more effectively. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of 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 per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
