Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs Radeon HD 7770
IntroThe GeForce 9500 GT 512MB GDDR3 features a GPU core speed of 550 MHz, and the 512 MB of GDDR3 memory is set to run at 800 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare all that to the Radeon HD 7770, which makes use of a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 7770 should be 181% quicker than the GeForce 9500 GT 512MB GDDR3 overall, because of its higher data rate. (explain)
Texel RateThe Radeon HD 7770 should be much (more or less 355%) faster with regards to AF than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 7770 is superior to the GeForce 9500 GT 512MB GDDR3, 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 maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
