Compare any two graphics cards:
GeForce GTX 285 1GB vs GeForce GTX 480
IntroThe GeForce GTX 285 1GB features a clock speed of 648 MHz and a GDDR3 memory speed of 1242 MHz. It also uses a 512-bit bus, and uses a 55 nm design. It is comprised of 240 SPUs, 80 TAUs, and 32 ROPs.Compare those specs to the GeForce GTX 480, which features GPU clock speed of 700 MHz, and 1536 MB of GDDR5 RAM running at 924 MHz through a 384-bit bus. It also is made up of 480 SPUs, 60 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 480 should in theory be a little bit faster than the GeForce GTX 285 1GB overall. (explain)
Texel RateThe GeForce GTX 285 1GB is a lot (approximately 23%) faster with regards to anisotropic filtering than the GeForce GTX 480. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 480 is superior to the GeForce GTX 285 1GB, and very much so. (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 (measured in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
