Radeon HD 5970 vs Radeon RX 6600 XT

Intro

Compare that to the Radeon RX 6600 XT, which has GPU core speed of 1968 MHz, and 8192 MB of GDDR6 memory running at 2000 MHz through a 128-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT		160 Watts
Radeon HD 5970		294 Watts
	Difference: 134 Watts (84%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6600 XT should be 2% quicker than the Radeon HD 5970 in general, because of its greater bandwidth. (explain)

Radeon RX 6600 XT		262144 MB/sec
Radeon HD 5970		256000 MB/sec
	Difference: 6144 (2%)

Texel Rate

The Radeon RX 6600 XT is a small bit (about 9%) faster with regards to anisotropic filtering than the Radeon HD 5970. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon HD 5970		232000 Mtexels/sec
	Difference: 19904 (9%)

Pixel Rate

The Radeon RX 6600 XT should be much (about 36%) better at anti-aliasing than the Radeon HD 5970, and capable of handling higher screen resolutions better. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon HD 5970		92800 Mpixels/sec
	Difference: 33152 (36%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. 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 card's memory bandwidth, the faster 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 can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
