Compare any two graphics cards:
GeForce 8800 GT 1GB vs Radeon HD 4770
IntroThe GeForce 8800 GT 1GB comes with a clock speed of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 256-bit bus, and uses a 65 nm design. It is made up of 112 SPUs, 56 Texture Address Units, and 16 ROPs.Compare those specifications to the Radeon HD 4770, which makes use of a 40 nm design. AMD has set the core speed at 750 MHz. The GDDR5 memory runs at a frequency of 800 MHz on this particular card. It features 640(128x5) SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 8800 GT 1GB should theoretically be a bit better than the Radeon HD 4770 overall. (explain)
Texel RateThe GeForce 8800 GT 1GB should be a lot (approximately 40%) better at AF than the Radeon HD 4770. (explain)
Pixel RateThe Radeon HD 4770 will be much (more or less 25%) faster with regards to FSAA than the GeForce 8800 GT 1GB, and also 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: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number 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 processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
