GeForce GT 430 (OEM) vs Radeon R9 M390X

Intro

Compare those specs to the Radeon R9 M390X, which uses a 28 nm design. AMD has clocked the core frequency at 723 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this specific card. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

Theoretically speaking, the Radeon R9 M390X will be 456% faster than the GeForce GT 430 (OEM) in general, due to its higher data rate. (explain)

Radeon R9 M390X		160000 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 131200 (456%)

Texel Rate

The Radeon R9 M390X should be much (more or less 726%) more effective at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

Radeon R9 M390X		92544 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 81344 (726%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M390X is the winner, by far. (explain)

Radeon R9 M390X		23136 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 20336 (726%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
