Compare any two graphics cards:
GeForce 9800 GT 512MB vs GeForce GT 240 GDDR5
IntroThe GeForce 9800 GT 512MB features clock speeds of 600 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the GeForce GT 240 GDDR5, which features GPU clock speed of 550 MHz, and 512 MB of GDDR5 memory running at 850 MHz through a 128-bit bus. It also features 96 Stream Processors, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 9800 GT 512MB should perform a small bit faster than the GeForce GT 240 GDDR5 overall. (explain)
Texel RateThe GeForce 9800 GT 512MB should be a lot (about 91%) better at texture filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce 9800 GT 512MB is superior to the GeForce GT 240 GDDR5, by far. (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 MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, 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 that the graphics card can 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 clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
