Compare any two graphics cards:
Geforce GTX 670 vs Radeon R9 M390X
IntroThe Geforce GTX 670 comes with a clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It features 1344 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.Compare all of that to the Radeon R9 M390X, which uses a 28 nm design. AMD has clocked the core speed at 723 MHz. The GDDR5 RAM works at a speed of 1250 MHz on this card. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Geforce GTX 670 should theoretically perform a small bit faster than the Radeon R9 M390X overall. (explain)
Texel RateThe Geforce GTX 670 is a little bit (about 11%) better at AF than the Radeon R9 M390X. (explain)
Pixel RateThe Geforce GTX 670 is quite a bit (approximately 27%) better at full screen anti-aliasing than the Radeon R9 M390X, and will be able to handle higher screen resolutions more effectively. (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 largest amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should 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 high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
