Compare any two graphics cards:
GeForce GTS 150 vs Radeon HD 6790
IntroThe GeForce GTS 150 features a GPU core clock speed of 740 MHz, and the 1024 MB of GDDR3 RAM is set to run at 500 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 Texture Address Units, and 16 ROPs.Compare all that to the Radeon HD 6790, which makes use of a 40 nm design. AMD has set the core speed at 840 MHz. The GDDR5 RAM works at a speed of 1050 MHz on this particular card. It features 800 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6790, in theory, should be much faster than the GeForce GTS 150 in general. (explain)
Texel RateThe GeForce GTS 150 will be a lot (approximately 41%) faster with regards to texture filtering than the Radeon HD 6790. (explain)
Pixel RateThe Radeon HD 6790 is a bit (more or less 14%) faster with regards to AA than the GeForce GTS 150, and able to handle higher 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 megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses 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 high 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 number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
