Compare any two graphics cards:
GeForce 8800 Ultra vs Radeon R9 M280X
IntroThe GeForce 8800 Ultra makes use of a 90 nm design. nVidia has clocked the core frequency at 612 MHz. The GDDR3 RAM runs at a speed of 1080 MHz on this model. It features 128 SPUs as well as 64 TAUs and 24 Rasterization Operator Units.Compare all of that to the Radeon R9 M280X, which has a GPU core clock speed of 900 MHz, and 4096 MB of GDDR5 memory running at 1375 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 8800 Ultra should in theory be just a bit better than the Radeon R9 M280X in general. (explain)
Texel RateThe Radeon R9 M280X should be quite a bit (more or less 29%) more effective at anisotropic filtering than the GeForce 8800 Ultra. (explain)
Pixel RateThe GeForce 8800 Ultra should be a bit (approximately 2%) better at anti-aliasing than the Radeon R9 M280X, and also will be capable of handling higher screen resolutions without slowing down too much. (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 largest amount of information (in units of MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, 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 chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
