Compare any two graphics cards:
GeForce GT 240 GDDR5 vs GeForce GTX 470
IntroThe GeForce GT 240 GDDR5 has a GPU clock speed of 550 MHz, and the 512 MB of GDDR5 RAM runs at 850 MHz through a 128-bit bus. It also is made up of 96 SPUs, 32 Texture Address Units, and 8 ROPs.Compare all that to the GeForce GTX 470, which uses a 40 nm design. nVidia has clocked the core speed at 607 MHz. The GDDR5 RAM runs at a speed of 837 MHz on this particular card. It features 448 SPUs as well as 56 TAUs and 40 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 470 is 146% quicker than the GeForce GT 240 GDDR5 overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 470 is much (approximately 93%) faster with regards to AF than the GeForce GT 240 GDDR5. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 470 is superior to the GeForce GT 240 GDDR5, by a large margin. (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 max amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
