GeForce GT 430 (OEM) vs Radeon RX 580

Intro

Compare all of that to the Radeon RX 580, which comes with core clock speeds of 1257 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs along with 144 TAUs and 32 ROPs.

Texel Rate

The Radeon RX 580 should be quite a bit (approximately 1516%) better at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

Radeon RX 580		181008 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 169808 (1516%)

Pixel Rate

The Radeon RX 580 is quite a bit (more or less 1337%) faster with regards to anti-aliasing than the GeForce GT 430 (OEM), and should be able to handle higher resolutions more effectively. (explain)

Radeon RX 580		40224 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 37424 (1337%)

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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
