Compare any two graphics cards:
GeForce GTX 460 1GB vs Radeon HD 5870
IntroThe GeForce GTX 460 1GB has a GPU core speed of 675 MHz, and the 1024 MB of GDDR5 memory is set to run at 900 MHz through a 256-bit bus. It also features 336 Stream Processors, 56 Texture Address Units, and 32 ROPs.
Compare those specs to the Radeon HD 5870, which makes use of a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory runs at a speed of 1200 MHz on this specific model. It features 1600(320x5) SPUs as well as 80 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 5870 will be 33% faster than the GeForce GTX 460 1GB overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 5870 is a lot (more or less 80%) more effective at AF than the GeForce GTX 460 1GB. (explain)
Pixel RateThe Radeon HD 5870 should be a lot (more or less 26%) better at AA than the GeForce GTX 460 1GB, and will be capable of handling higher resolutions without losing too much performance. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes 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 speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better 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 most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
