Compare any two graphics cards:
GeForce GTX 560 Ti 448 vs Radeon HD 6770 1GB
IntroThe GeForce GTX 560 Ti 448 has a GPU core clock speed of 732 MHz, and the 1280 MB of GDDR5 memory is set to run at 900 MHz through a 320-bit bus. It also features 448 Stream Processors, 56 TAUs, and 40 Raster Operation Units.Compare those specs to the Radeon HD 6770 1GB, which features a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is made up of 800 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 560 Ti 448 should theoretically be quite a bit faster than the Radeon HD 6770 1GB in general. (explain)
Texel RateThe GeForce GTX 560 Ti 448 is a little bit (approximately 14%) more effective at texture filtering than the Radeon HD 6770 1GB. (explain)
Pixel RateThe GeForce GTX 560 Ti 448 is a lot (more or less 103%) better at AA than the Radeon HD 6770 1GB, and will be able to handle 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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
