Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 XT 50th Anniversary Edition will be 1409% quicker than the Radeon HD 3470 512MB in general, because of its higher bandwidth. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 428352 (1409%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition is a lot (approximately 8300%) more effective at texture filtering than the Radeon HD 3470 512MB. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 265600 (8300%)

Pixel Rate

The Radeon RX 5700 XT 50th Anniversary Edition is a lot (approximately 3260%) more effective at anti-aliasing than the Radeon HD 3470 512MB, and also will be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 104320 (3260%)

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 information (measured in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
