Compare any two graphics cards:
GeForce 8600 GS (OEM) vs Radeon HD 6790
IntroThe GeForce 8600 GS (OEM) comes with core clock speeds of 540 MHz on the GPU, and 400 MHz on the 256 MB of DDR2 RAM. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare those specs to the Radeon HD 6790, which features a GPU core clock speed of 840 MHz, and 1024 MB of GDDR5 memory running at 1050 MHz through a 256-bit bus. It also is made up of 800 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6790 should perform a lot faster than the GeForce 8600 GS (OEM) overall. (explain)
Texel RateThe Radeon HD 6790 is a lot (more or less 289%) better at anisotropic filtering than the GeForce 8600 GS (OEM). (explain)
Pixel RateThe Radeon HD 6790 should be much (approximately 211%) more effective at full screen anti-aliasing than the GeForce 8600 GS (OEM), and should be capable of handling higher screen 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 data (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 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 AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number 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 outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
