Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 6870
IntroThe GeForce GTX 550 Ti comes with a clock frequency of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also makes use of a 192-bit bus, and uses a 40 nm design. It features 192 SPUs, 32 TAUs, and 24 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 is made up of 1120 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 6870 should theoretically perform much faster than the GeForce GTX 550 Ti overall. (explain)
Texel RateThe Radeon HD 6870 will be a lot (about 75%) faster with regards to anisotropic filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe Radeon HD 6870 should be a lot (about 33%) faster with regards to anti-aliasing than the GeForce GTX 550 Ti, and also should be able to handle higher resolutions more effectively. (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 information (counted in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core 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 per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
