Compare any two graphics cards:
Radeon HD 4550 512MB vs Radeon HD 7750
IntroThe Radeon HD 4550 512MB makes use of a 55 nm design. AMD has set the core frequency at 600 MHz. The GDDR3 RAM runs at a frequency of 800 MHz on this model. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 ROPs.Compare all of that to the Radeon HD 7750, which makes use of a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this specific model. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7750 should be much faster than the Radeon HD 4550 512MB in general. (explain)
Texel RateThe Radeon HD 7750 will be much (approximately 433%) better at texture filtering than the Radeon HD 4550 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 7750 is a better choice, and very much so. (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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 can be processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on 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 memory bandwidth is, the lower the potential to reach the max fill rate.
