Compare any two graphics cards:
Radeon HD 6770 1GB vs Radeon R7 M260X
IntroThe Radeon HD 6770 1GB has a core clock speed of 900 MHz and a GDDR5 memory speed of 1050 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It features 800 SPUs, 40 TAUs, and 16 ROPs.Compare that to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this particular model. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 6770 1GB should theoretically be just a bit faster than the Radeon R7 M260X overall. (explain)
Texel RateThe Radeon HD 6770 1GB should be much (about 82%) more effective at texture filtering than the Radeon R7 M260X. (explain)
Pixel RateThe Radeon HD 6770 1GB is much (more or less 118%) faster with regards to anti-aliasing than the Radeon R7 M260X, and also capable of handling higher screen resolutions more effectively. (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 largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core 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 applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
