Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 6870
IntroThe GeForce GTX 550 Ti has a GPU core speed of 900 MHz, and the 1024 MB of GDDR5 memory is set to run at 1026 MHz through a 192-bit bus. It also is comprised of 192 SPUs, 32 Texture Address Units, and 24 ROPs.Compare all that to the Radeon HD 6870, which uses a 40 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 RAM is set to run at a speed of 1050 MHz on this model. It features 1120 SPUs as well as 56 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6870 should in theory be a lot faster than the GeForce GTX 550 Ti in general. (explain)
Texel RateThe Radeon HD 6870 will be quite a bit (about 75%) faster with regards to AF than the GeForce GTX 550 Ti. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 6870 is superior to the GeForce GTX 550 Ti, 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 information (in units of MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units 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 processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
