Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce GTX 660 Ti features a GPU clock speed of 915 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1500 MHz through a 192-bit bus. It also is made up of 1344 Stream Processors, 112 TAUs, and 24 Raster Operation Units.Compare that to the Radeon HD 6670 (OEM) 1GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this card. It features 480 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 660 Ti should be quite a bit faster than the Radeon HD 6670 (OEM) 1GB overall. (explain)
Texel RateThe GeForce GTX 660 Ti should be much (about 434%) faster with regards to anisotropic filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTX 660 Ti is a lot (approximately 243%) faster with regards to FSAA than the Radeon HD 6670 (OEM) 1GB, and also able to handle higher resolutions without slowing down too much. (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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
