Compare any two graphics cards:
Radeon R9 270 vs Radeon R9 285
IntroThe Radeon R9 270 has a GPU core clock speed of 900 MHz, and the 2048 MB of GDDR5 RAM runs at 1400 MHz through a 256-bit bus. It also is made up of 1280 Stream Processors, 80 Texture Address Units, and 32 ROPs.Compare that to the Radeon R9 285, which makes use of a 28 nm design. AMD has clocked the core speed at 918 MHz. The GDDR5 RAM works at a speed of 1375 MHz on this specific model. It features 1792 SPUs as well as 112 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 270 should in theory perform a bit faster than the Radeon R9 285 overall. (explain)
Texel RateThe Radeon R9 285 will be a lot (more or less 43%) more effective at anisotropic filtering than the Radeon R9 270. (explain)
Pixel RateThe Radeon R9 285 should be a little bit (approximately 2%) faster with regards to AA than the Radeon R9 270, and capable of handling higher screen resolutions without slowing down too much. (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 information (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has 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 texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
