Compare any two graphics cards:
Radeon R9 285 vs Radeon R9 380 4G
IntroThe Radeon R9 285 comes with a clock frequency of 918 MHz and a GDDR5 memory frequency of 1375 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 32 ROPs.Compare those specs to the Radeon R9 380 4G, which comes with core clock speeds of 970 MHz on the GPU, and 1425 MHz on the 4096 MB of GDDR5 memory. It features 1792 SPUs along with 112 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthThe Radeon R9 380 4G should theoretically perform a little bit faster than the Radeon R9 285 in general. (explain)
Texel RateThe Radeon R9 380 4G will be a bit (about 6%) faster with regards to texture filtering than the Radeon R9 285. (explain)
Pixel RateThe Radeon R9 380 4G should be just a bit (about 6%) more effective at AA than the Radeon R9 285, and also should be able to handle 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB 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 speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock 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 applied in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
