Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs GeForce GT 240 GDDR5
IntroThe GeForce 9500 GT 1GB GDDR3 features a clock frequency of 550 MHz and a GDDR3 memory speed of 800 MHz. It also makes use of a 128-bit memory bus, and makes use of a 55 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare all that to the GeForce GT 240 GDDR5, which has a clock speed of 550 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is made up of 96 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 240 GDDR5 will be 113% quicker than the GeForce 9500 GT 1GB GDDR3 in general, due to its greater data rate. (explain)
Texel RateThe GeForce GT 240 GDDR5 will be much (approximately 100%) faster with regards to AF than the GeForce 9500 GT 1GB GDDR3. (explain)
Pixel RateBoth cards have exactly the same pixel fill rate, so in theory they should be equally good at at anti-aliasing, 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. 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. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a 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. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
