Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 6900 XT should be quite a bit faster than the Radeon HD 3470 512MB in general. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 493888 (1625%)

Texel Rate

The Radeon RX 6900 XT is a lot (more or less 18150%) faster with regards to texture filtering than the Radeon HD 3470 512MB. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 580800 (18150%)

Pixel Rate

The Radeon RX 6900 XT should be much (about 7200%) more effective at AA than the Radeon HD 3470 512MB, and also able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 230400 (7200%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at 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 record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
