Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs GeForce GT 240 GDDR5 1GB
IntroThe GeForce 9500 GT 1GB GDDR3 features a clock speed of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also features a 128-bit bus, and makes use of a 55 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.Compare all that to the GeForce GT 240 GDDR5 1GB, which makes use of a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 RAM runs at a speed of 850 MHz on this model. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 240 GDDR5 1GB will be 113% faster than the GeForce 9500 GT 1GB GDDR3 overall, due to its higher data rate. (explain)
Texel RateThe GeForce GT 240 GDDR5 1GB will be much (approximately 100%) better at AF than the GeForce 9500 GT 1GB GDDR3. (explain)
Pixel RateBoth cards have the exact same pixel rate, so theoretically they should perform equally good at at anti-aliasing, and be capable of handling the same screen resolutions. (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 over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
