Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 670		170 Watts
Radeon RX 6650 XT		176 Watts
	Difference: 6 Watts (4%)

Memory Bandwidth

In theory, the Radeon RX 6650 XT will be 50% quicker than the Geforce GTX 670 in general, due to its higher data rate. (explain)

Radeon RX 6650 XT		287072 MB/sec
Geforce GTX 670		192000 MB/sec
	Difference: 95072 (50%)

Texel Rate

The Radeon RX 6650 XT will be a lot (about 157%) more effective at texture filtering than the Geforce GTX 670. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 160560 (157%)

Pixel Rate

The Radeon RX 6650 XT will be quite a bit (more or less 349%) better at anti-aliasing than the Geforce GTX 670, and able to handle higher resolutions more effectively. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 102240 (349%)

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 MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that are applied per 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
