Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs GeForce GTX 580 3GB
IntroThe GeForce 9500 GT 512MB GDDR3 uses a 55 nm design. nVidia has set the core frequency at 550 MHz. The GDDR3 memory is set to run at a speed of 800 MHz on this model. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the GeForce GTX 580 3GB, which comes with a core clock frequency of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also features a 384-bit memory bus, and uses a 40 nm design. It is made up of 512 SPUs, 64 TAUs, and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 580 3GB should in theory be quite a bit superior to the GeForce 9500 GT 512MB GDDR3 in general. (explain)
Texel RateThe GeForce GTX 580 3GB is quite a bit (approximately 461%) more effective at texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateThe GeForce GTX 580 3GB should be a lot (more or less 742%) better at full screen anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and also able to handle higher screen resolutions without slowing down too much. (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 information (measured in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core clock 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 processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its 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 called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
