Compare any two graphics cards:
Radeon HD 7850 vs Radeon R7 260X
IntroThe Radeon HD 7850 has clock speeds of 860 MHz on the GPU, and 1200 MHz on the 2048 MB of GDDR5 RAM. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.
Compare those specs to the Radeon R7 260X, which uses 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 as well as 56 Texture Address Units and 16 ROPs.

As far as performance goes, the Radeon HD 7850 should in theory be a lot better than the Radeon R7 260X overall. (explain)
Texel RateThe Radeon R7 260X is a small bit (approximately 12%) better at anisotropic filtering than the Radeon HD 7850. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 7850 is superior to the Radeon R7 260X, 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.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core 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 reach the max fill rate.
