Compare any two graphics cards:
Radeon HD 3650 512MB vs Radeon HD 7750
IntroThe Radeon HD 3650 512MB makes use of a 55 nm design. AMD has clocked the core speed at 725 MHz. The GDDR3 memory runs at a frequency of 800 MHz on this particular model. It features 120(24x5) SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.Compare all that to the Radeon HD 7750, which uses a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this particular model. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 7750 should theoretically be a lot superior to the Radeon HD 3650 512MB overall. (explain)
Texel RateThe Radeon HD 7750 should be a lot (approximately 341%) faster with regards to AF than the Radeon HD 3650 512MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 7750 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: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at 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 the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
