Compare any two graphics cards:
GeForce GTX 280 vs Radeon HD 6870
IntroThe GeForce GTX 280 comes with a GPU core clock speed of 602 MHz, and the 1024 MB of GDDR3 RAM runs at 1107 MHz through a 512-bit bus. It also is comprised of 240 Stream Processors, 80 TAUs, and 32 ROPs.Compare those specs to the Radeon HD 6870, which makes use of a 40 nm design. AMD has set the core speed at 900 MHz. The GDDR5 memory works at a frequency of 1050 MHz on this particular model. It features 1120 SPUs along with 56 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 280 should in theory be just a bit superior to the Radeon HD 6870 overall. (explain)
Texel RateThe Radeon HD 6870 should be a little bit (more or less 5%) better at texture filtering than the GeForce GTX 280. (explain)
Pixel RateThe Radeon HD 6870 will be a lot (more or less 50%) better at full screen anti-aliasing than the GeForce GTX 280, and also capable of handling 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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the 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 that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
