Radeon HD 3470 512MB vs Radeon RX 6900 XT

Intro

The Radeon HD 3470 512MB comes with a GPU core clock speed of 800 MHz, and the 512 MB of GDDR3 RAM runs at 950 MHz through a 128-bit bus. It also features 40(8x5) Stream Processors, 4 TAUs, and 4 ROPs.

Compare those specs to the Radeon RX 6900 XT, which uses a 7 nm design. AMD has set the core frequency at 1825 MHz. The GDDR6 RAM works at a speed of 2000 MHz on this specific card. It features 5120 SPUs as well as 320 TAUs and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 6900 XT should perform a lot faster than the Radeon HD 3470 512MB overall. (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 will be much (about 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

If using high levels of AA is important to you, then the Radeon RX 6900 XT is superior to the Radeon HD 3470 512MB, 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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
