Compare any two graphics cards:
GeForce GT 240 GDDR5 vs GeForce GTX 465
IntroThe GeForce GT 240 GDDR5 makes use of a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 memory runs at a frequency of 850 MHz on this particular model. It features 96 SPUs as well as 32 Texture Address Units and 8 ROPs.Compare all that to the GeForce GTX 465, which comes with GPU core speed of 607 MHz, and 1024 MB of GDDR5 memory running at 802 MHz through a 256-bit bus. It also is made up of 352 Stream Processors, 44 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 465 should in theory be quite a bit superior to the GeForce GT 240 GDDR5 overall. (explain)
Texel RateThe GeForce GTX 465 will be quite a bit (about 52%) faster with regards to AF than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe GeForce GTX 465 will be a lot (approximately 341%) faster with regards to FSAA than the GeForce GT 240 GDDR5, and also should be able to handle higher screen resolutions while still performing well. (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 (measured in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that can be processed 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 video 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 the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
