Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon R9 M385X
IntroThe GeForce GTS 450 1GB comes with a core clock speed of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 16 ROPs.Compare those specs to the Radeon R9 M385X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this particular card. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 M385X should be much faster than the GeForce GTS 450 1GB overall. (explain)
Texel RateThe Radeon R9 M385X will be quite a bit (approximately 146%) more effective at AF than the GeForce GTS 450 1GB. (explain)
Pixel RateThe Radeon R9 M385X is quite a bit (about 40%) better at FSAA than the GeForce GTS 450 1GB, and should be capable of handling higher resolutions better. (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 maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 can be processed in one second. This is calculated by multiplying the total number of 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 applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
