GeForce GTX 970 vs Radeon RX 6600 XT

Intro

Compare those specifications to the Radeon RX 6600 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1968 MHz. The GDDR6 RAM works at a frequency of 2000 MHz on this card. It features 2048 SPUs along with 128 TAUs 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

In theory, the Radeon RX 6600 XT is 17% faster than the GeForce GTX 970 in general, because of its greater bandwidth. (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 quite a bit (about 131%) better at AF than the GeForce GTX 970. (explain)

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

Pixel Rate

The Radeon RX 6600 XT will be quite a bit (approximately 87%) better at full screen anti-aliasing than the GeForce GTX 970, and also able to handle higher resolutions without slowing down too much. (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: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
