Compare any two graphics cards:
GeForce GT 430 vs Radeon HD 6770 1GB
IntroThe GeForce GT 430 makes use of a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this card. It features 96 SPUs as well as 16 TAUs and 4 Rasterization Operator Units.Compare all that to the Radeon HD 6770 1GB, which features GPU core speed of 900 MHz, and 1024 MB of GDDR5 RAM running at 1050 MHz through a 128-bit bus. It also features 800 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6770 1GB, in theory, should perform a lot faster than the GeForce GT 430 in general. (explain)
Texel RateThe Radeon HD 6770 1GB is a lot (about 221%) better at anisotropic filtering than the GeForce GT 430. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 6770 1GB is superior to the GeForce GT 430, by far. (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 largest amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
