GeForce GTX 650		64 Watts
Radeon RX 5600 XT		160 Watts
	Difference: 96 Watts (150%)

Memory Bandwidth

In theory, the Radeon RX 5600 XT should perform much faster than the GeForce GTX 650 in general. (explain)

Radeon RX 5600 XT		344064 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 264064 (330%)

Texel Rate

The Radeon RX 5600 XT will be much (about 485%) better at texture filtering than the GeForce GTX 650. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 164144 (485%)

Pixel Rate

The Radeon RX 5600 XT is quite a bit (approximately 420%) faster with regards to anti-aliasing than the GeForce GTX 650, and also will be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 71072 (420%)

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 information (counted in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 are applied in one second. This number is calculated by multiplying the total texture units 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 in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can 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 card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
