GeForce GT 430 (OEM) vs Radeon RX 580

Intro

Compare those specifications to the Radeon RX 580, which has a GPU core clock speed of 1257 MHz, and 8192 MB of GDDR5 memory set to run at 2000 MHz through a 256-bit bus. It also is comprised of 2304 SPUs, 144 TAUs, and 32 ROPs.

GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 233344 (810%)

Texel Rate

The Radeon RX 580 is quite a bit (about 1516%) faster with regards to AF 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 screen resolution is important to you, then the Radeon RX 580 is a better choice, and very much so. (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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at 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 can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
