Compare any two graphics cards:
GeForce 8800 GT 1GB vs GeForce GT 240 GDDR5 1GB
IntroThe GeForce 8800 GT 1GB uses a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 memory runs at a speed of 900 MHz on this particular model. It features 112 SPUs along with 56 Texture Address Units and 16 ROPs.Compare that to the GeForce GT 240 GDDR5 1GB, which has core speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 96 SPUs along with 32 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 8800 GT 1GB should in theory be a small bit better than the GeForce GT 240 GDDR5 1GB in general. (explain)
Texel RateThe GeForce 8800 GT 1GB will be much (about 91%) faster with regards to AF than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateThe GeForce 8800 GT 1GB will be much (approximately 118%) more effective at FSAA than the GeForce GT 240 GDDR5 1GB, and capable of handling 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: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
