Compare any two graphics cards:
GeForce GTX 260 vs Radeon R9 M390X
IntroThe GeForce GTX 260 features a core clock frequency of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also makes use of a 448-bit memory bus, and makes use of a 65 nm design. It is made up of 192 SPUs, 64 Texture Address Units, and 28 Raster Operation Units.Compare those specs to the Radeon R9 M390X, which comes with a core clock frequency of 723 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 256-bit bus, and uses a 28 nm design. It features 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 M390X should in theory be much superior to the GeForce GTX 260 in general. (explain)
Texel RateThe Radeon R9 M390X should be quite a bit (about 151%) faster with regards to texture filtering than the GeForce GTX 260. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 M390X is superior to the GeForce GTX 260, 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 megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. 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 bandwidth is, the lower the potential to reach the max fill rate.
