Compare any two graphics cards:
GeForce GTX 280 vs GeForce GTX 285 1GB
IntroThe GeForce GTX 280 comes with core speeds of 602 MHz on the GPU, and 1107 MHz on the 1024 MB of GDDR3 RAM. It features 240 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.Compare those specs to the GeForce GTX 285 1GB, which features a core clock frequency of 648 MHz and a GDDR3 memory frequency of 1242 MHz. It also features a 512-bit bus, and makes use of a 55 nm design. It is made up of 240 SPUs, 80 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 285 1GB should perform a little bit faster than the GeForce GTX 280 in general. (explain)
Texel RateThe GeForce GTX 285 1GB will be a small bit (about 8%) more effective at texture filtering than the GeForce GTX 280. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 285 1GB is a better choice, not by a very large margin though. (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 max amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once 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, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the 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 graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate 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 get to the maximum fill rate.
