Compare any two graphics cards:
GeForce RTX 2080 vs Radeon R9 M390X
IntroThe GeForce RTX 2080 features a core clock speed of 1515 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 256-bit bus, and uses a 12 nm design. It is made up of 2944 SPUs, 184 TAUs, and 64 Raster Operation Units.Compare those specs to the Radeon R9 M390X, which uses a 28 nm design. AMD has clocked the core speed at 723 MHz. The GDDR5 RAM is set to run at a speed of 1250 MHz on this particular card. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce RTX 2080 should perform quite a bit faster than the Radeon R9 M390X overall. (explain)
Texel RateThe GeForce RTX 2080 will be a lot (approximately 201%) better at AF than the Radeon R9 M390X. (explain)
Pixel RateThe GeForce RTX 2080 should be quite a bit (more or less 319%) better at AA than the Radeon R9 M390X, and capable of handling higher screen resolutions without slowing down too much. (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 data (measured in MB per second) that can be transferred over the external memory interface within a 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 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 AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card 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 processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number 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 outputting the pixels (image) to the screen. 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 potential to reach the max fill rate.
