Compare any two graphics cards:
Radeon HD 7870 XT vs Radeon R9 380 4G
IntroThe Radeon HD 7870 XT uses a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 memory runs at a frequency of 1500 MHz on this particular model. It features 1536 SPUs as well as 96 TAUs and 32 ROPs.Compare that to the Radeon R9 380 4G, which has GPU core speed of 970 MHz, and 4096 MB of GDDR5 memory set to run at 1425 MHz through a 256-bit bus. It also features 1792 SPUs, 112 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 7870 XT should perform a small bit faster than the Radeon R9 380 4G overall. (explain)
Texel RateThe Radeon R9 380 4G will be a lot (approximately 22%) faster with regards to texture filtering than the Radeon HD 7870 XT. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon R9 380 4G is a better choice, though not by far. (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 (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses 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, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 bandwidth is, the lower the ability to get to the maximum fill rate.
