Compare any two graphics cards:
Radeon R9 270 vs Radeon R9 M395X
IntroThe Radeon R9 270 features core clock speeds of 900 MHz on the GPU, and 1400 MHz on the 2048 MB of GDDR5 memory. It features 1280 SPUs along with 80 TAUs and 32 ROPs.Compare those specs to the Radeon R9 M395X, which has a GPU core clock speed of 723 MHz, and 4096 MB of GDDR5 memory running at 1250 MHz through a 256-bit bus. It also features 2048 Stream Processors, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 270 should in theory be a bit faster than the Radeon R9 M395X overall. (explain)
Texel RateThe Radeon R9 M395X should be much (more or less 29%) better at AF than the Radeon R9 270. (explain)
Pixel RateThe Radeon R9 270 will be a lot (about 24%) faster with regards to anti-aliasing than the Radeon R9 M395X, and able to handle higher 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: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
