Compare any two graphics cards:
Radeon HD 7870 XT vs Radeon R9 M295X
IntroThe Radeon HD 7870 XT comes with a GPU core 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 those specifications to the Radeon R9 M295X, which makes use of a 28 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM works at a frequency of 1375 MHz on this card. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7870 XT should be 9% quicker than the Radeon R9 M295X in general, because of its higher bandwidth. (explain)
Texel RateThe Radeon R9 M295X will be a little bit (approximately 8%) better at texture filtering than the Radeon HD 7870 XT. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 7870 XT is the winner, and very much so. (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 largest amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
