Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 6670 (OEM)
IntroThe GeForce GTS 450 1GB uses a 40 nm design. nVidia has set the core frequency at 783 MHz. The GDDR5 RAM works at a frequency of 902 MHz on this specific card. It features 192 SPUs along with 32 TAUs and 16 ROPs.Compare those specifications to the Radeon HD 6670 (OEM), which uses a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this specific card. It features 480 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6670 (OEM) should be 11% quicker than the GeForce GTS 450 1GB overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTS 450 1GB should be a lot (about 31%) faster with regards to anisotropic filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTS 450 1GB is superior to the Radeon HD 6670 (OEM), 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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
