Compare any two graphics cards:
GeForce GTX 460 1GB vs Radeon HD 6870
IntroThe GeForce GTX 460 1GB makes use of a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 RAM works at a speed of 900 MHz on this model. It features 336 SPUs as well as 56 TAUs and 32 ROPs.
Compare those specifications to the Radeon HD 6870, which features GPU core speed of 900 MHz, and 1024 MB of GDDR5 RAM set to run at 1050 MHz through a 256-bit bus. It also features 1120 Stream Processors, 56 TAUs, and 32 ROPs.

Radeon HD 6870 wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the Radeon HD 6870 wins overall, by 21 FPS. Please note that we do not have the results of every benchmark ever done for these cards, so the results may differ wildly in different games.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 6870 is 17% faster than the GeForce GTX 460 1GB in general, due to its greater data rate. (explain)
Texel RateThe Radeon HD 6870 should be a lot (about 33%) better at anisotropic filtering than the GeForce GTX 460 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 6870 is superior to the GeForce GTX 460 1GB, by a large margin. (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 (measured in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of 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 processed in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs 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 ability to get to the max fill rate.
