Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon HD 6790
IntroThe GeForce GTX 285 1GB uses a 55 nm design. nVidia has set the core frequency at 648 MHz. The GDDR3 memory is set to run at a speed of 1242 MHz on this particular model. It features 240 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.Compare all that to the Radeon HD 6790, which uses a 40 nm design. AMD has clocked the core frequency at 840 MHz. The GDDR5 memory is set to run at a speed of 1050 MHz on this specific 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 GeForce GTX 285 1GB should in theory be just a bit faster than the Radeon HD 6790 overall. (explain)
Texel RateThe GeForce GTX 285 1GB is a lot (more or less 54%) more effective at texture filtering than the Radeon HD 6790. (explain)
Pixel RateThe GeForce GTX 285 1GB should be quite a bit (about 54%) faster with regards to FSAA than the Radeon HD 6790, and should be capable of handling higher screen 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 information (counted in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). 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 maximum fill rate.
