GeForce GT 430 vs Radeon RX 580

Intro

Compare those specs to the Radeon RX 580, which comes with GPU core speed of 1257 MHz, and 8192 MB of GDDR5 memory set to run at 2000 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 TAUs, and 32 ROPs.

Power Consumption (Max TDP)

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

Memory Bandwidth

The Radeon RX 580 should in theory be quite a bit faster than the GeForce GT 430 in general. (explain)

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

Texel Rate

The Radeon RX 580 is much (about 1516%) more effective at texture filtering than the GeForce GT 430. (explain)

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

Pixel Rate

The Radeon RX 580 should be a lot (more or less 1337%) more effective at AA than the GeForce GT 430, and also should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 580		40224 Mpixels/sec
GeForce GT 430		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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record 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 card's 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 also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
