Radeon HD 5970 vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which features GPU core speed of 1626 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 128-bit bus. It also is made up of 1792 SPUs, 112 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the Radeon HD 5970 should perform a small bit faster than the Radeon RX 6600 overall. (explain)

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

Texel Rate

The Radeon HD 5970 will be a lot (more or less 27%) faster with regards to 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

The Radeon RX 6600 is just a bit (more or less 12%) more effective at FSAA than the Radeon HD 5970, and should be able to handle higher screen resolutions while still performing well. (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 largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
