Compare any two graphics cards:
Radeon HD 4850 2GB vs Radeon HD 5750 1GB
IntroThe Radeon HD 4850 2GB makes use of a 55 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR4 memory works at a frequency of 993 MHz on this specific model. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 5750 1GB, which features GPU core speed of 700 MHz, and 1024 MB of GDDR5 RAM set to run at 1150 MHz through a 128-bit bus. It also features 720(144x5) Stream Processors, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5750 1GB should be 16% quicker than the Radeon HD 4850 2GB overall, due to its greater data rate. (explain)
Texel RateThe Radeon HD 5750 1GB should be a small bit (approximately 1%) faster with regards to anisotropic filtering than the Radeon HD 4850 2GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 5750 1GB is a better choice, but only just. (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 largest amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
