GeForce GTX 1070 Ti vs Radeon RX 6600 XT

Intro

The GeForce GTX 1070 Ti comes with clock speeds of 1607 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2432 SPUs along with 152 Texture Address Units and 64 Rasterization Operator Units.

Compare those specifications to the Radeon RX 6600 XT, which has clock speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 RAM. 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 perform the same. (explain)

Texel Rate

The Radeon RX 6600 XT should be a bit (approximately 3%) better at 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

If running with lots of anti-aliasing is important to you, then the Radeon RX 6600 XT is a better choice, by far. (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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are processed per 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 memory bandwidth is, the lower the potential to get to the maximum fill rate.
