Compare any two graphics cards:
Radeon HD 7870 XT vs Radeon R9 380 4G
IntroThe Radeon HD 7870 XT features a GPU core clock speed of 925 MHz, and the 2048 MB of GDDR5 memory is set to run at 1500 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 96 TAUs, and 32 Raster Operation Units.Compare all of that to the Radeon R9 380 4G, which comes with core speeds of 970 MHz on the GPU, and 1425 MHz on the 4096 MB of GDDR5 memory. It features 1792 SPUs along with 112 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7870 XT should in theory perform a small bit faster than the Radeon R9 380 4G overall. (explain)
Texel RateThe Radeon R9 380 4G should be quite a bit (approximately 22%) faster with regards to anisotropic filtering than the Radeon HD 7870 XT. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R9 380 4G is superior to the Radeon HD 7870 XT, though only just barely. (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 maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it 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 can be processed per second. This is calculated by multiplying the total 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 applied in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
