Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650		64 Watts
Radeon RX 5500 XT		130 Watts
	Difference: 66 Watts (103%)

Memory Bandwidth

In theory, the Radeon RX 5500 XT is 187% quicker than the GeForce GTX 650 overall, due to its higher bandwidth. (explain)

Radeon RX 5500 XT		229376 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 149376 (187%)

Texel Rate

The Radeon RX 5500 XT is quite a bit (more or less 346%) better at AF than the GeForce GTX 650. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 117240 (346%)

Pixel Rate

The Radeon RX 5500 XT should be much (about 225%) faster with regards to full screen anti-aliasing than the GeForce GTX 650, and also will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 38016 (225%)

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 data (measured in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
