Radeon HD 3470 256MB vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which comes with a core clock speed of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 7 nm design. It is comprised of 5120 SPUs, 320 TAUs, and 128 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 6900 XT should theoretically perform quite a bit faster than the Radeon HD 3470 256MB overall. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon HD 3470 256MB		30400 MB/sec
	Difference: 493888 (1625%)

Texel Rate

The Radeon RX 6900 XT is much (more or less 18150%) more effective at AF than the Radeon HD 3470 256MB. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon HD 3470 256MB		3200 Mtexels/sec
	Difference: 580800 (18150%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6900 XT is superior to the Radeon HD 3470 256MB, by a large margin. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon HD 3470 256MB		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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
