Compare any two graphics cards:
Radeon HD 3650 256MB vs Radeon HD 6570 (OEM) 2GB
IntroThe Radeon HD 3650 256MB comes with a core clock speed of 725 MHz and a DDR2 memory frequency of 800 MHz. It also makes use of a 128-bit memory bus, and makes use of a 55 nm design. It is made up of 120(24x5) SPUs, 8 Texture Address Units, and 4 ROPs.Compare that to the Radeon HD 6570 (OEM) 2GB, which has a clock frequency of 650 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 6570 (OEM) 2GB should perform quite a bit faster than the Radeon HD 3650 256MB overall. (explain)
Texel RateThe Radeon HD 6570 (OEM) 2GB is much (about 169%) faster with regards to texture filtering than the Radeon HD 3650 256MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 6570 (OEM) 2GB is superior to the Radeon HD 3650 256MB, by a large margin. (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 max amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core 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 applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
