Compare any two graphics cards:
Radeon HD 5570 vs Radeon HD 6450 (OEM)
IntroThe Radeon HD 5570 uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 RAM runs at a speed of 900 MHz on this particular model. It features 400(80x5) SPUs along with 20 Texture Address Units and 8 ROPs.Compare those specs to the Radeon HD 6450 (OEM), which uses a 40 nm design. AMD has set the core frequency at 625 MHz. The GDDR3 memory runs at a frequency of 800 MHz on this specific card. It features 160 SPUs as well as 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5570, in theory, should perform quite a bit faster than the Radeon HD 6450 (OEM) overall. (explain)
Texel RateThe Radeon HD 5570 is a lot (approximately 160%) more effective at AF than the Radeon HD 6450 (OEM). (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 5570 is a better choice, by far. (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 largest amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
