GeForce GTX 980 Ti vs Radeon RX 6600 XT

Intro

Compare all that to the Radeon RX 6600 XT, which features core speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 RAM. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

Radeon RX 6600 XT		160 Watts
GeForce GTX 980 Ti		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

The GeForce GTX 980 Ti, in theory, should be quite a bit faster than the Radeon RX 6600 XT in general. (explain)

GeForce GTX 980 Ti		336000 MB/sec
Radeon RX 6600 XT		262144 MB/sec
	Difference: 73856 (28%)

Texel Rate

The Radeon RX 6600 XT is a lot (about 43%) more effective at texture filtering than the GeForce GTX 980 Ti. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 75904 (43%)

Pixel Rate

If running with 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 980 Ti		96000 Mpixels/sec
	Difference: 29952 (31%)

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 (counted in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record 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 core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
