Compare any two graphics cards:
GeForce GTX 460 1GB vs Radeon HD 5870
IntroThe GeForce GTX 460 1GB features a core clock speed of 675 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 256-bit bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.
Compare all that to the Radeon HD 5870, which makes use of a 40 nm design. AMD has clocked the core speed at 850 MHz. The GDDR5 RAM runs at a speed of 1200 MHz on this specific card. It features 1600(320x5) SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 5870 should in theory perform quite a bit faster than the GeForce GTX 460 1GB overall. (explain)
Texel RateThe Radeon HD 5870 will be a lot (more or less 80%) better at anisotropic filtering than the GeForce GTX 460 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 5870 is superior to the GeForce GTX 460 1GB, 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.
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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
