GeForce GTX 970 vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which features a GPU core clock speed of 1968 MHz, and 8192 MB of GDDR6 RAM running at 2000 MHz through a 128-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 64 Raster Operation 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

The Radeon RX 6600 XT should in theory perform just a 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 a lot (about 131%) more effective 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 using lots of anti-aliasing 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 largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
