Compare any two graphics cards:
Radeon HD 6670 (OEM) vs Radeon HD 6950 2GB
IntroThe Radeon HD 6670 (OEM) comes with a GPU core speed of 800 MHz, and the 512 MB of GDDR5 memory runs at 1000 MHz through a 128-bit bus. It also features 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.Compare that to the Radeon HD 6950 2GB, which features GPU core speed of 800 MHz, and 2048 MB of GDDR5 memory running at 1250 MHz through a 256-bit bus. It also features 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 6950 2GB should perform quite a bit faster than the Radeon HD 6670 (OEM) in general. (explain)
Texel RateThe Radeon HD 6950 2GB is much (about 267%) faster with regards to anisotropic filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateThe Radeon HD 6950 2GB is a lot (more or less 300%) better at full screen anti-aliasing than the Radeon HD 6670 (OEM), and also will be capable of handling higher resolutions while still performing well. (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 information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
