Radeon HD 3470 256MB		30400 MB/sec
	Difference: 428352 (1409%)

Texel Rate

The Radeon RX 5700 XT will be much (about 7925%) better at anisotropic filtering than the Radeon HD 3470 256MB. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon HD 3470 256MB		3200 Mtexels/sec
	Difference: 253600 (7925%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 5700 XT is a better choice, by far. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon HD 3470 256MB		3200 Mpixels/sec
	Difference: 99520 (3110%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
