Compare any two graphics cards:
Radeon HD 6570 (OEM) 1GB vs Radeon HD 6950 2GB
IntroThe Radeon HD 6570 (OEM) 1GB uses a 40 nm design. AMD has clocked the core speed at 650 MHz. The GDDR3 memory works at a frequency of 900 MHz on this card. It features 480 SPUs as well as 24 Texture Address Units and 8 ROPs.Compare those specifications to the Radeon HD 6950 2GB, which makes use of a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM runs at a speed of 1250 MHz on this card. It features 1408 SPUs as well as 88 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6950 2GB, in theory, should be much faster than the Radeon HD 6570 (OEM) 1GB in general. (explain)
Texel RateThe Radeon HD 6950 2GB will be a lot (about 351%) better at anisotropic filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 6950 2GB is superior to the Radeon HD 6570 (OEM) 1GB, by a large margin. (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 largest amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
