Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 6870
IntroThe GeForce GTX 260 Core 216 uses a 65 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 RAM runs at a speed of 999 MHz on this model. It features 216 SPUs along with 72 Texture Address Units and 28 ROPs.Compare that to the Radeon HD 6870, which comes with core speeds of 900 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 RAM. It features 1120 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6870 should be 20% faster than the GeForce GTX 260 Core 216 in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 6870 should be much (about 22%) faster with regards to texture filtering than the GeForce GTX 260 Core 216. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 6870 is superior to the GeForce GTX 260 Core 216, and very much so. (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 information (counted in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
