Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Geforce GTX 670		170 Watts
	Difference: 40 Watts (31%)

Memory Bandwidth

In theory, the Radeon RX 5500 XT will be 19% faster than the Geforce GTX 670 in general, because of its greater data rate. (explain)

Radeon RX 5500 XT		229376 MB/sec
Geforce GTX 670		192000 MB/sec
	Difference: 37376 (19%)

Texel Rate

The Radeon RX 5500 XT will be much (about 47%) more effective at AF than the Geforce GTX 670. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 48616 (47%)

Pixel Rate

The Radeon RX 5500 XT will be quite a bit (more or less 88%) more effective at anti-aliasing than the Geforce GTX 670, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 25664 (88%)

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 data (measured in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 reach the maximum fill rate.
