Compare any two graphics cards:
GeForce 8800 GTX vs Radeon HD 5870
IntroThe GeForce 8800 GTX has core speeds of 575 MHz on the GPU, and 900 MHz on the 768 MB of GDDR3 memory. It features 128 SPUs along with 64 TAUs and 24 Rasterization Operator Units.Compare those specs to the Radeon HD 5870, which comes with GPU clock speed of 850 MHz, and 1024 MB of GDDR5 RAM set to run at 1200 MHz through a 256-bit bus. It also is comprised of 1600(320x5) SPUs, 80 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 5870 should perform much faster than the GeForce 8800 GTX in general. (explain)
Texel RateThe Radeon HD 5870 will be quite a bit (approximately 85%) more effective at AF than the GeForce 8800 GTX. (explain)
Pixel RateThe Radeon HD 5870 will be much (about 97%) faster with regards to full screen anti-aliasing than the GeForce 8800 GTX, and will be 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 largest amount of data (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 interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
