GeForce GT 430 (OEM) vs Radeon RX 580

Intro

Compare that to the Radeon RX 580, which features GPU core speed of 1257 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also features 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

GeForce GT 430 (OEM)		60 Watts
Radeon RX 580		185 Watts
	Difference: 125 Watts (208%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 580 should be 810% faster than the GeForce GT 430 (OEM) overall, because of its greater bandwidth. (explain)

Radeon RX 580		262144 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 233344 (810%)

Texel Rate

The Radeon RX 580 is a lot (about 1516%) more effective 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

If running with a high resolution is important to you, then the Radeon RX 580 is the winner, by a large margin. (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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video 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 Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
