Radeon HD 3470 512MB vs Radeon RX 6900 XT

Intro

Compare all of that to the Radeon RX 6900 XT, which uses a 7 nm design. AMD has set the core speed at 1825 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this particular card. It features 5120 SPUs along with 320 Texture Address Units and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 6900 XT should theoretically perform a lot 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 should be much (more or less 18150%) more effective at AF 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

If running with a high resolution is important to you, then the Radeon RX 6900 XT is a better choice, by far. (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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total 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 one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
