Compare any two graphics cards:
Radeon HD 5870 vs Radeon R9 M390X
IntroThe Radeon HD 5870 uses a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory is set to run at a speed of 1200 MHz on this card. It features 1600(320x5) SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.Compare all that to the Radeon R9 M390X, which features a core clock frequency of 723 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 256-bit memory bus, and makes use of 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 BandwidthTheoretically speaking, the Radeon R9 M390X should be a little bit faster than the Radeon HD 5870 overall. (explain)
Texel RateThe Radeon R9 M390X is quite a bit (about 36%) faster with regards to anisotropic filtering than the Radeon HD 5870. (explain)
Pixel RateThe Radeon HD 5870 will be just a bit (approximately 18%) faster with regards to AA than the Radeon R9 M390X, and will be able to handle higher resolutions better. (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 maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
