Compare any two graphics cards:
Radeon R9 280X vs Radeon R9 285
IntroThe Radeon R9 280X uses a 28 nm design. AMD has set the core speed at 850 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this specific card. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.Compare all of that to the Radeon R9 285, which comes with GPU clock speed of 918 MHz, and 2048 MB of GDDR5 RAM set to run at 1375 MHz through a 256-bit bus. It also features 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 280X should be quite a bit faster than the Radeon R9 285 overall. (explain)
Texel RateThe Radeon R9 280X will be a small bit (about 6%) better at anisotropic filtering than the Radeon R9 285. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 285 is superior to the Radeon R9 280X, but only just. (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 maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
