Compare any two graphics cards:
Radeon HD 6770 1GB vs Radeon R9 380 2G
IntroThe Radeon HD 6770 1GB comes with a GPU core clock speed of 900 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1050 MHz through a 128-bit bus. It also is comprised of 800 Stream Processors, 40 TAUs, and 16 ROPs.Compare those specifications to the Radeon R9 380 2G, which features GPU clock speed of 970 MHz, and 2048 MB of GDDR5 memory set to run at 1425 MHz through a 256-bit bus. It also is made up of 1792 SPUs, 112 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 380 2G should be 171% faster than the Radeon HD 6770 1GB in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon R9 380 2G will be quite a bit (more or less 202%) faster with regards to AF than the Radeon HD 6770 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R9 380 2G 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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics 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 most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units 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 is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
