Compare any two graphics cards:
GeForce GT 450 (OEM) vs Radeon HD 6670 (OEM)
IntroThe GeForce GT 450 (OEM) has a GPU core speed of 790 MHz, and the 1536 MB of GDDR5 memory runs at 1000 MHz through a 192-bit bus. It also is comprised of 144 SPUs, 24 TAUs, and 24 Raster Operation Units.Compare those specs to the Radeon HD 6670 (OEM), which makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this particular model. It features 480 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 450 (OEM) should theoretically perform much faster than the Radeon HD 6670 (OEM) in general. (explain)
Texel RateThe Radeon HD 6670 (OEM) should be a bit (more or less 1%) more effective at AF than the GeForce GT 450 (OEM). (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GT 450 (OEM) 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
