Compare any two graphics cards:
GeForce 9800 GT 1GB vs Radeon HD 6770 1GB
IntroThe GeForce 9800 GT 1GB makes use of a 65/55 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this particular card. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 6770 1GB, which has a clock speed 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 BandwidthTheoretically speaking, the Radeon HD 6770 1GB is 17% quicker than the GeForce 9800 GT 1GB overall, because of its higher bandwidth. (explain)
Texel RateThe Radeon HD 6770 1GB should be a little bit (more or less 7%) faster with regards to texture filtering than the GeForce 9800 GT 1GB. (explain)
Pixel RateThe Radeon HD 6770 1GB will be quite a bit (about 50%) better at AA than the GeForce 9800 GT 1GB, and also should be able to handle higher resolutions more effectively. (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 maximum amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
