Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
Radeon HD 6790		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6790 is 3% quicker than the GeForce GTX 1650 in general, because of its higher data rate. (explain)

Radeon HD 6790		134400 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 3328 (3%)

Texel Rate

The GeForce GTX 1650 is much (more or less 148%) more effective at AF than the Radeon HD 6790. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 6790		33600 Mtexels/sec
	Difference: 49560 (148%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1650 is superior to the Radeon HD 6790, and very much so. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 6790		13440 Mpixels/sec
	Difference: 34080 (254%)

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 largest amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated 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 graphics 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 number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core 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 also depends 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.
