Compare any two graphics cards:
Radeon HD 6670 (OEM) vs Radeon HD 6770 1GB
IntroThe Radeon HD 6670 (OEM) comes with a GPU core speed of 800 MHz, and the 512 MB of GDDR5 memory is set to run at 1000 MHz through a 128-bit bus. It also is made up of 480 SPUs, 24 Texture Address Units, and 8 ROPs.Compare those specifications to the Radeon HD 6770 1GB, which comes with clock speeds of 900 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 RAM. It features 800 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6770 1GB should theoretically be a small bit superior to the Radeon HD 6670 (OEM) in general. (explain)
Texel RateThe Radeon HD 6770 1GB is a lot (more or less 88%) faster with regards to AF than the Radeon HD 6670 (OEM). (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6770 1GB is a better choice, 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: Bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one 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 the texel rate, the better the 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 most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
