Compare any two graphics cards:
GeForce GTX 460 1GB vs Radeon HD 6790
IntroThe GeForce GTX 460 1GB makes use of a 40 nm design. nVidia has set the core speed at 675 MHz. The GDDR5 RAM runs at a speed of 900 MHz on this specific card. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.Compare all of that to the Radeon HD 6790, which uses a 40 nm design. AMD has clocked the core frequency at 840 MHz. The GDDR5 RAM runs at a frequency of 1050 MHz on this model. It features 800 SPUs as well as 40 Texture Address Units and 16 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6790 will be 17% quicker than the GeForce GTX 460 1GB overall, due to its higher data rate. (explain)
Texel RateThe GeForce GTX 460 1GB should be just a bit (more or less 13%) faster with regards to AF than the Radeon HD 6790. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 460 1GB is the winner, 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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses 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 high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core 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 is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
