Compare any two graphics cards:
Radeon R9 380 4G vs Radeon R9 M395X
IntroThe Radeon R9 380 4G uses a 28 nm design. AMD has clocked the core speed at 970 MHz. The GDDR5 RAM runs at a speed of 1425 MHz on this particular model. It features 1792 SPUs along with 112 TAUs and 32 ROPs.Compare all that to the Radeon R9 M395X, which has a clock frequency of 723 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 380 4G should in theory be a small bit better than the Radeon R9 M395X in general. (explain)
Texel RateThe Radeon R9 380 4G is a bit (about 17%) faster with regards to AF than the Radeon R9 M395X. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 380 4G is superior to the Radeon R9 M395X, 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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
