Compare any two graphics cards:
Radeon HD 3650 vs Radeon HD 6750
IntroThe Radeon HD 3650 has a core clock speed of 725 MHz and a GDDR4 memory frequency of 800 MHz. It also makes use of a 128-bit memory bus, and uses a 55 nm design. It is made up of 120(24x5) SPUs, 8 TAUs, and 4 ROPs.Compare that to the Radeon HD 6750, which comes with GPU core speed of 725 MHz, and 512 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 720 SPUs, 36 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6750, in theory, should be much faster than the Radeon HD 3650 overall. (explain)
Texel RateThe Radeon HD 6750 should be a lot (about 350%) more effective at anisotropic filtering than the Radeon HD 3650. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 6750 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 max amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card 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 applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
