Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce GTX 550 Ti features clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs as well as 32 TAUs and 24 Rasterization Operator Units.
Compare that to the Radeon HD 6670 (OEM) 1GB, which makes use of a 40 nm design. ATi has set the core speed at 800 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this specific card. It features 480 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 550 Ti should be 54% faster than the Radeon HD 6670 (OEM) 1GB overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 550 Ti should be quite a bit (approximately 50%) more effective at anisotropic filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTX 550 Ti should be much (about 238%) better at FSAA than the Radeon HD 6670 (OEM) 1GB, and also 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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock 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 better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher 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 most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 reach the maximum fill rate.
