Compare any two graphics cards:
GeForce GT 440 1.5GB vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce GT 440 1.5GB features a core clock speed of 594 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 192-bit bus, and makes use of a 40 nm design. It is comprised of 144 SPUs, 24 Texture Address Units, and 24 Raster Operation Units.Compare those specs to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this specific card. It features 480 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6670 (OEM) 1GB should be 48% faster than the GeForce GT 440 1.5GB in general, due to its greater data rate. (explain)
Texel RateThe Radeon HD 6670 (OEM) 1GB should be a lot (about 35%) more effective at texture filtering than the GeForce GT 440 1.5GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GT 440 1.5GB is a better choice, 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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
