Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 580 3GB
IntroThe GeForce GTX 550 Ti has a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also makes use of a 192-bit bus, and makes use of a 40 nm design. It is comprised of 192 SPUs, 32 Texture Address Units, and 24 Raster Operation Units.Compare all that to the GeForce GTX 580 3GB, which features a clock speed of 772 MHz and a GDDR5 memory speed of 1002 MHz. It also features a 384-bit memory bus, and uses a 40 nm design. It is made up of 512 SPUs, 64 Texture Address Units, and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 580 3GB should be 95% faster than the GeForce GTX 550 Ti overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 580 3GB should be much (approximately 72%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 580 3GB should be quite a bit (more or less 72%) better at FSAA than the GeForce GTX 550 Ti, and also will be able to handle higher screen resolutions while still performing well. (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

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many 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.
