GeForce GTX 970 vs Radeon RX 6600 XT

Intro

Compare all of that to the Radeon RX 6600 XT, which features a core clock speed of 1968 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 128-bit bus, and makes use of a 7 nm design. It features 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

GeForce GTX 970		145 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 15 Watts (10%)

Memory Bandwidth

The Radeon RX 6600 XT should in theory be a little bit faster than the GeForce GTX 970 overall. (explain)

Radeon RX 6600 XT		262144 MB/sec
GeForce GTX 970		224000 MB/sec
	Difference: 38144 (17%)

Texel Rate

The Radeon RX 6600 XT will be a lot (about 131%) better at anisotropic filtering than the GeForce GTX 970. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
GeForce GTX 970		109200 Mtexels/sec
	Difference: 142704 (131%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6600 XT is the winner, and very much so. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce GTX 970		67200 Mpixels/sec
	Difference: 58752 (87%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure 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 drawing the pixels (image) on the screen. The actual pixel fill 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.
