Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6650 XT		176 Watts
GeForce GTX 1070 Ti		180 Watts
	Difference: 4 Watts (2%)

Memory Bandwidth

In theory, the Radeon RX 6650 XT will be 10% faster than the GeForce GTX 1070 Ti in general, because of its higher bandwidth. (explain)

Radeon RX 6650 XT		287072 MB/sec
GeForce GTX 1070 Ti		262144 MB/sec
	Difference: 24928 (10%)

Texel Rate

The Radeon RX 6650 XT should be just a bit (about 8%) faster with regards to texture filtering than the GeForce GTX 1070 Ti. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce GTX 1070 Ti		244264 Mtexels/sec
	Difference: 18776 (8%)

Pixel Rate

The Radeon RX 6650 XT will be a lot (more or less 28%) better at anti-aliasing than the GeForce GTX 1070 Ti, and also capable of handling higher resolutions more effectively. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce GTX 1070 Ti		102848 Mpixels/sec
	Difference: 28672 (28%)

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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
