Compare any two graphics cards:
Radeon R9 380 2G vs Radeon R9 M295X
IntroThe Radeon R9 380 2G makes use of a 28 nm design. AMD has clocked the core frequency at 970 MHz. The GDDR5 RAM is set to run at a frequency of 1425 MHz on this card. It features 1792 SPUs along with 112 Texture Address Units and 32 ROPs.Compare all that to the Radeon R9 M295X, which makes use of a 28 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 memory works at a frequency of 1375 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 380 2G will be 4% faster than the Radeon R9 M295X overall, because of its higher bandwidth. (explain)
Texel RateThe Radeon R9 380 2G will be a bit (about 13%) more effective at AF than the Radeon R9 M295X. (explain)
Pixel RateThe Radeon R9 380 2G is quite a bit (approximately 29%) more effective at full screen anti-aliasing than the Radeon R9 M295X, and will be able to handle higher screen resolutions without losing too much performance. (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 max amount of data (measured in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 applied in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
