Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs GeForce GT 240 GDDR5 1GB
IntroThe GeForce 9500 GT 512MB GDDR3 features core clock speeds of 550 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.Compare those specs to the GeForce GT 240 GDDR5 1GB, which comes with a GPU core clock speed of 550 MHz, and 1024 MB of GDDR5 RAM running at 850 MHz through a 128-bit bus. It also is made up of 96 SPUs, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GT 240 GDDR5 1GB should in theory be much superior to the GeForce 9500 GT 512MB GDDR3 overall. (explain)
Texel RateThe GeForce GT 240 GDDR5 1GB is quite a bit (approximately 100%) more effective at texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateBoth cards have the exact same pixel fill rate, so in theory they should perform equally good at at FSAA, and be capable of handling the same 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: 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 calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 can be applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling 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 one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
