Compare any two graphics cards:
GeForce GT 450 (OEM) vs Radeon R9 M390X
IntroThe GeForce GT 450 (OEM) makes use of a 40 nm design. nVidia has set the core speed at 790 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this model. It features 144 SPUs along with 24 Texture Address Units and 24 ROPs.Compare those specifications to the Radeon R9 M390X, which uses a 28 nm design. AMD has clocked the core frequency at 723 MHz. The GDDR5 RAM runs at a speed of 1250 MHz on this card. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 M390X should theoretically be much faster than the GeForce GT 450 (OEM) in general. (explain)
Texel RateThe Radeon R9 M390X is much (approximately 388%) better at texture filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R9 M390X is superior to the GeForce GT 450 (OEM), 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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better 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 the graphics card can possibly record to the 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 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 rate is also dependant on lots of 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.
