Compare any two graphics cards:
Radeon HD 4830 512MB vs Radeon HD 6570 (OEM) 1GB
IntroThe Radeon HD 4830 512MB features a clock speed of 575 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit memory bus, and uses a 55 nm design. It is comprised of 640(128x5) SPUs, 32 Texture Address Units, and 16 ROPs.Compare those specs to the Radeon HD 6570 (OEM) 1GB, which comes with a clock speed of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4830 512MB, in theory, should be much faster than the Radeon HD 6570 (OEM) 1GB in general. (explain)
Texel RateThe Radeon HD 4830 512MB should be a little bit (more or less 18%) more effective at texture filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 4830 512MB is the winner, 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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better 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 one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
