GeForce GTX 1070 Ti vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which features clock 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 Rasterization Operator Units.

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 memory bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The Radeon RX 6600 XT will be a little bit (approximately 3%) faster with regards to anisotropic 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

The Radeon RX 6600 XT should be a lot (more or less 22%) better at full screen anti-aliasing than the GeForce GTX 1070 Ti, and able to handle higher resolutions while still performing well. (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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
