GeForce GTX 1070 Ti vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which comes with core speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 memory. It features 2048 SPUs along with 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT		160 Watts
GeForce GTX 1070 Ti		180 Watts
	Difference: 20 Watts (13%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The Radeon RX 6600 XT is just a bit (about 3%) faster with regards to texture filtering than the GeForce GTX 1070 Ti. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
GeForce GTX 1070 Ti		244264 Mtexels/sec
	Difference: 7640 (3%)

Pixel Rate

If running with a high 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 1070 Ti		102848 Mpixels/sec
	Difference: 23104 (22%)

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 max amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at 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 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 Raster Operations Pipelines by the the core clock speed. 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 lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
