Compare any two graphics cards:
Radeon R7 260X vs Radeon R9 M390X
IntroThe Radeon R7 260X has a GPU core speed of 1100 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1625 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 Texture Address Units, and 16 ROPs.Compare those specs to the Radeon R9 M390X, which features a clock frequency of 723 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It features 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 M390X should in theory be quite a bit superior to the Radeon R7 260X overall. (explain)
Texel RateThe Radeon R9 M390X is a lot (about 50%) faster with regards to anisotropic filtering than the Radeon R7 260X. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon R9 M390X is superior to the Radeon R7 260X, 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 max amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If 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 texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
