Compare any two graphics cards:
Radeon R9 285 vs Radeon R9 380 2G
IntroThe Radeon R9 285 comes with a core clock speed of 918 MHz and a GDDR5 memory speed of 1375 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is made up of 1792 SPUs, 112 TAUs, and 32 ROPs.
Compare that to the Radeon R9 380 2G, which has a core clock frequency of 970 MHz and a GDDR5 memory speed of 1425 MHz. It also features a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1792 SPUs, 112 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Theoretically speaking, the Radeon R9 380 2G is 4% faster than the Radeon R9 285 overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon R9 380 2G should be a small bit (about 6%) faster with regards to AF than the Radeon R9 285. (explain)
Pixel RateThe Radeon R9 380 2G is a bit (approximately 6%) better at FSAA than the Radeon R9 285, and should be capable of handling higher 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core clock 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 processed per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock 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 is also dependant 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 max fill rate.
