Radeon HD 5970 vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which has core speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 1792 SPUs as well as 112 Texture Address Units and 64 Rasterization Operator Units.

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

Texel Rate

The Radeon HD 5970 will be much (about 27%) more effective at texture 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 using a high resolution is important to you, then the Radeon RX 6600 is a better choice, but not by far. (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: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
