GeForce GT 430 vs Radeon RX 580

Intro

Compare that to the Radeon RX 580, which has clock speeds of 1257 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2304 SPUs as well as 144 TAUs and 32 Rasterization Operator Units.

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

Texel Rate

The Radeon RX 580 is a lot (approximately 1516%) faster with regards to AF 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 will be much (about 1337%) better at full screen anti-aliasing than the GeForce GT 430, and also able to handle higher screen resolutions better. (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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record 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 clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
