Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470 4GB		120 Watts
Radeon RX 6700 XT		230 Watts
	Difference: 110 Watts (92%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6700 XT should be 86% faster than the Radeon RX 470 4GB overall, because of its higher bandwidth. (explain)

Radeon RX 6700 XT		393216 MB/sec
Radeon RX 470 4GB		211200 MB/sec
	Difference: 182016 (86%)

Texel Rate

The Radeon RX 6700 XT is much (about 213%) faster with regards to AF than the Radeon RX 470 4GB. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 252832 (213%)

Pixel Rate

The Radeon RX 6700 XT is quite a bit (more or less 401%) faster with regards to full screen anti-aliasing than the Radeon RX 470 4GB, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 118912 (401%)

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 information (measured in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 are applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
