Compare any two graphics cards:
GeForce GT 240 GDDR5 vs GeForce GT 440 3GB
IntroThe GeForce GT 240 GDDR5 makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 memory works at a frequency of 850 MHz on this particular model. It features 96 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.Compare all of that to the GeForce GT 440 3GB, which uses a 40 nm design. nVidia has clocked the core frequency at 594 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this specific card. It features 144 SPUs along with 24 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GT 240 GDDR5 should theoretically be quite a bit superior to the GeForce GT 440 3GB overall. (explain)
Texel RateThe GeForce GT 240 GDDR5 is a lot (more or less 23%) more effective at AF than the GeForce GT 440 3GB. (explain)
Pixel RateThe GeForce GT 440 3GB is a lot (approximately 224%) faster with regards to FSAA than the GeForce GT 240 GDDR5, and will be able to handle higher screen resolutions more effectively. (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 maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
