Compare any two graphics cards:
GeForce 8800 GT 256MB vs GeForce GT 340 1GB
IntroThe GeForce 8800 GT 256MB makes use of a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 memory runs at a speed of 700 MHz on this card. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the GeForce GT 340 1GB, which has GPU clock speed of 550 MHz, and 1024 MB of GDDR5 memory set to run at 850 MHz through a 128-bit bus. It also features 96 SPUs, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GT 340 1GB should perform much faster than the GeForce 8800 GT 256MB overall. (explain)
Texel RateThe GeForce 8800 GT 256MB is a lot (about 91%) faster with regards to AF than the GeForce GT 340 1GB. (explain)
Pixel RateThe GeForce 8800 GT 256MB should be a lot (approximately 118%) more effective at AA than the GeForce GT 340 1GB, and also should be capable of handling higher screen resolutions without losing too much performance. (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 maximum amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
