Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs GeForce GT 240 GDDR5
IntroThe GeForce 9500 GT 1GB GDDR3 features core clock speeds of 550 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR3 RAM. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.
Compare those specifications to the GeForce GT 240 GDDR5, which features a core clock frequency of 550 MHz and a GDDR5 memory speed of 850 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is made up of 96 SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GT 240 GDDR5 will be 113% quicker than the GeForce 9500 GT 1GB GDDR3 overall, due to its higher data rate. (explain)
Texel RateThe GeForce GT 240 GDDR5 will be much (approximately 100%) better at texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)
Pixel RateBoth cards have the exact same pixel rate, so theoretically they should be equally good at at AA, and be able to handle 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 number of texture map elements (texels) that can be applied 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 graphics card will be at handling 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 could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
