Compare any two graphics cards:
Radeon HD 6770 vs Radeon R7 260X
IntroThe Radeon HD 6770 has a core clock speed of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is made up of 800 SPUs, 40 TAUs, and 16 ROPs.Compare those specs to the Radeon R7 260X, which makes use of a 28 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 RAM works at a speed of 1625 MHz on this particular model. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R7 260X should perform quite a bit faster than the Radeon HD 6770 in general. (explain)
Texel RateThe Radeon R7 260X will be much (approximately 71%) better at AF than the Radeon HD 6770. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon R7 260X is a better choice, and very much so. (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 moved over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should 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, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends 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.
