GeForce GTX 970 vs Radeon RX 6600 XT

Intro

Compare all of that to the Radeon RX 6600 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 1968 MHz. The GDDR6 RAM works at a frequency of 2000 MHz on this particular card. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically, the Radeon RX 6600 XT should be a small 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 should be much (more or less 131%) better at texture 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 running with a high screen resolution is important to you, then the Radeon RX 6600 XT is a better choice, 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 information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines 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 fill 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.
