Compare any two graphics cards:
Radeon HD 7850 vs Radeon R9 280X
IntroThe Radeon HD 7850 uses a 28 nm design. AMD has set the core frequency at 860 MHz. The GDDR5 memory is set to run at a speed of 1200 MHz on this specific card. It features 1024 SPUs along with 64 TAUs and 32 ROPs.
Compare those specs to the Radeon R9 280X, which has GPU core speed of 850 MHz, and 3072 MB of GDDR5 memory running at 1500 MHz through a 384-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon R9 280X should theoretically perform much faster than the Radeon HD 7850 in general. (explain)
Texel RateThe Radeon R9 280X will be a lot (about 98%) faster with regards to anisotropic filtering than the Radeon HD 7850. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 7850 is a better choice, but it probably won't make a huge difference. (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 maximum amount of data (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once 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 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 worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per 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 speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
