Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 4870 512MB
IntroThe GeForce GTX 550 Ti has a GPU core clock speed of 900 MHz, and the 1024 MB of GDDR5 RAM runs at 1026 MHz through a 192-bit bus. It also features 192 SPUs, 32 TAUs, and 24 ROPs.Compare all that to the Radeon HD 4870 512MB, which comes with GPU core speed of 750 MHz, and 512 MB of GDDR5 RAM running at 900 MHz through a 256-bit bus. It also is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4870 512MB is 17% faster than the GeForce GTX 550 Ti in general, because of its higher bandwidth. (explain)
Texel RateThe Radeon HD 4870 512MB should be just a bit (about 4%) faster with regards to AF than the GeForce GTX 550 Ti. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 550 Ti is superior to the Radeon HD 4870 512MB, 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
