Compare any two graphics cards:
GeForce 9800 GT 1GB vs GeForce GT 240 GDDR5 1GB
IntroThe GeForce 9800 GT 1GB features a GPU core speed of 600 MHz, and the 1024 MB of GDDR3 memory runs at 900 MHz through a 256-bit bus. It also is made up of 112 Stream Processors, 56 TAUs, and 16 ROPs.Compare those specs to the GeForce GT 240 GDDR5 1GB, which uses a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this specific card. It features 96 SPUs as well as 32 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 9800 GT 1GB should theoretically be a bit faster than the GeForce GT 240 GDDR5 1GB in general. (explain)
Texel RateThe GeForce 9800 GT 1GB will be much (approximately 91%) faster with regards to AF than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateThe GeForce 9800 GT 1GB is a lot (about 118%) better at AA than the GeForce GT 240 GDDR5 1GB, and will be able to handle higher resolutions without slowing down too much. (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 transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its 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 core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
