Compare any two graphics cards:
GeForce 9800 GT 1GB vs Radeon HD 6770 1GB
IntroThe GeForce 9800 GT 1GB comes with a GPU core clock speed of 600 MHz, and the 1024 MB of GDDR3 memory is set to run at 900 MHz through a 256-bit bus. It also is comprised of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.Compare all of that to the Radeon HD 6770 1GB, which makes use of a 40 nm design. AMD has set the core speed at 900 MHz. The GDDR5 RAM is set to run at a speed of 1050 MHz on this card. It features 800 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6770 1GB should in theory be just a bit better than the GeForce 9800 GT 1GB overall. (explain)
Texel RateThe Radeon HD 6770 1GB will be a bit (about 7%) more effective at anisotropic filtering than the GeForce 9800 GT 1GB. (explain)
Pixel RateThe Radeon HD 6770 1GB will be much (more or less 50%) more effective at FSAA than the GeForce 9800 GT 1GB, and also able to handle higher screen resolutions better. (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 data (in units of MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total 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 in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the 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 the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
