Radeon HD 5970 vs Radeon RX 6500 XT

Intro

The Radeon HD 5970 has a clock frequency of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It features 1600 SPUs, 160 TAUs, and 64 Raster Operation Units.

Compare those specs to the Radeon RX 6500 XT, which has core clock speeds of 2200 MHz on the GPU, and 2250 MHz on the 4096 MB of GDDR6 memory. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT 107 Watts
Radeon HD 5970 294 Watts
Difference: 187 Watts (175%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5970 should be quite a bit faster than the Radeon RX 6500 XT in general. (explain)

Radeon HD 5970 256000 MB/sec
Radeon RX 6500 XT 147456 MB/sec
Difference: 108544 (74%)

Texel Rate

The Radeon HD 5970 is a lot (more or less 65%) better at anisotropic filtering than the Radeon RX 6500 XT. (explain)

Radeon HD 5970 232000 Mtexels/sec
Radeon RX 6500 XT 140800 Mtexels/sec
Difference: 91200 (65%)

Pixel Rate

The Radeon HD 5970 is much (more or less 32%) faster with regards to AA than the Radeon RX 6500 XT, and also able to handle higher resolutions while still performing well. (explain)

Radeon HD 5970 92800 Mpixels/sec
Radeon RX 6500 XT 70400 Mpixels/sec
Difference: 22400 (32%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can 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 speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
