Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4350		22 Watts
Radeon RX 570		150 Watts
	Difference: 128 Watts (582%)

Memory Bandwidth

In theory, the Radeon RX 570 is 2767% faster than the Radeon HD 4350 in general, because of its higher data rate. (explain)

Radeon RX 570		229376 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 221376 (2767%)

Texel Rate

The Radeon RX 570 should be much (more or less 3150%) faster with regards to AF than the Radeon HD 4350. (explain)

Radeon RX 570		149504 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 144904 (3150%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 570 is the winner, and very much so. (explain)

Radeon RX 570		37376 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 35076 (1525%)

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 max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
