Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1060 3GB		120 Watts
Radeon RX 6650 XT		176 Watts
	Difference: 56 Watts (47%)

Memory Bandwidth

In theory, the Radeon RX 6650 XT is 46% faster than the GeForce GTX 1060 3GB overall, because of its greater data rate. (explain)

Radeon RX 6650 XT		287072 MB/sec
GeForce GTX 1060 3GB		196608 MB/sec
	Difference: 90464 (46%)

Texel Rate

The Radeon RX 6650 XT should be a lot (more or less 143%) more effective at anisotropic filtering than the GeForce GTX 1060 3GB. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce GTX 1060 3GB		108432 Mtexels/sec
	Difference: 154608 (143%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6650 XT is a better choice, and very much so. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce GTX 1060 3GB		72288 Mpixels/sec
	Difference: 59232 (82%)

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 max amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
