Compare any two graphics cards:
Radeon HD 7850 vs Radeon R9 280X
IntroThe Radeon HD 7850 uses a 28 nm design. AMD has clocked the core frequency at 860 MHz. The GDDR5 memory is set to run at a speed of 1200 MHz on this model. It features 1024 SPUs along with 64 Texture Address Units and 32 ROPs.
Compare those specs to the Radeon R9 280X, which features a core clock speed of 850 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 384-bit bus, and makes use of a 28 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Consumption (Max TDP)
Theoretically speaking, the Radeon R9 280X will be 88% quicker than the Radeon HD 7850 overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon R9 280X will be a lot (more or less 98%) better at texture filtering than the Radeon HD 7850. (explain)
Pixel RateThe Radeon HD 7850 is just a bit (more or less 1%) more effective at full screen anti-aliasing than the Radeon R9 280X, and able to handle higher screen resolutions while still performing well. (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 (measured in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
