Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 6670 (OEM)
IntroThe GeForce GTX 550 Ti comes with a core clock speed of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also features a 192-bit bus, and makes use of a 40 nm design. It is comprised of 192 SPUs, 32 TAUs, and 24 Raster Operation Units.
Compare all of that to the Radeon HD 6670 (OEM), which makes use of a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this specific card. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 550 Ti should theoretically be quite a bit superior to the Radeon HD 6670 (OEM) in general. (explain)
Texel RateThe GeForce GTX 550 Ti will be much (more or less 50%) faster with regards to anisotropic filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 550 Ti is the winner, and very much so. (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 max amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
