Compare any two graphics cards:
GeForce GTX 285 2GB vs Geforce GTX 680
IntroThe GeForce GTX 285 2GB uses a 55 nm design. nVidia has clocked the core speed at 648 MHz. The GDDR3 RAM is set to run at a speed of 1242 MHz on this specific model. It features 240 SPUs along with 80 TAUs and 32 ROPs.Compare all that to the Geforce GTX 680, which comes with GPU core speed of 1006 MHz, and 2048 MB of GDDR5 RAM running at 1502 MHz through a 256-bit bus. It also features 1536 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Geforce GTX 680 should be quite a bit faster than the GeForce GTX 285 2GB in general. (explain)
Texel RateThe Geforce GTX 680 will be a lot (approximately 148%) more effective at anisotropic filtering than the GeForce GTX 285 2GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Geforce GTX 680 is superior to the GeForce GTX 285 2GB, by a large margin. (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 information (counted in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
