Radeon HD 5970 vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which makes use of a 7 nm design. AMD has set the core speed at 1626 MHz. The GDDR6 RAM is set to run at a frequency of 1750 MHz on this particular model. It features 1792 SPUs along with 112 Texture Address Units and 64 ROPs.

Radeon RX 6600		132 Watts
Radeon HD 5970		294 Watts
	Difference: 162 Watts (123%)

Memory Bandwidth

In theory, the Radeon HD 5970 should perform a small bit faster than the Radeon RX 6600 in general. (explain)

Radeon HD 5970		256000 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 26624 (12%)

Texel Rate

The Radeon HD 5970 is quite a bit (more or less 27%) better at anisotropic filtering than the Radeon RX 6600. (explain)

Radeon HD 5970		232000 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 49888 (27%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6600 is superior to the Radeon HD 5970, though only just barely. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon HD 5970		92800 Mpixels/sec
	Difference: 11264 (12%)

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: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends 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 max fill rate.
