Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650		64 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 186 Watts (291%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6750 XT will be 453% faster than the GeForce GTX 650 in general, because of its higher data rate. (explain)

Radeon RX 6750 XT		442368 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 362368 (453%)

Texel Rate

The Radeon RX 6750 XT is quite a bit (more or less 916%) more effective at texture filtering than the GeForce GTX 650. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 310144 (916%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6750 XT is superior to the GeForce GTX 650, by a large margin. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 120672 (713%)

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 largest amount of data (in units of MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write 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 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
