Compare any two graphics cards:
GeForce GTX 460 (OEM) vs Radeon R9 M390X
IntroThe GeForce GTX 460 (OEM) features core speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.Compare that to the Radeon R9 M390X, which features a clock frequency of 723 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 M390X should in theory be much faster than the GeForce GTX 460 (OEM) in general. (explain)
Texel RateThe Radeon R9 M390X should be quite a bit (more or less 154%) faster with regards to AF than the GeForce GTX 460 (OEM). (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon R9 M390X is superior to the GeForce GTX 460 (OEM), though not by far. (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 across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once 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 is worked out by multiplying the total 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of 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.
