Compare any two graphics cards:
Geforce GTX 670 vs Radeon HD 6850
IntroThe Geforce GTX 670 makes use of a 28 nm design. nVidia has set the core speed at 915 MHz. The GDDR5 memory works at a speed of 1500 MHz on this model. It features 1344 SPUs along with 112 Texture Address Units and 32 Rasterization Operator Units.Compare all that to the Radeon HD 6850, which features clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 960 SPUs as well as 48 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Geforce GTX 670 should in theory be much better than the Radeon HD 6850 in general. (explain)
Texel RateThe Geforce GTX 670 is quite a bit (about 175%) more effective at AF than the Radeon HD 6850. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Geforce GTX 670 is a better choice, though not by far. (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 max amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core 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 applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
