Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB		110 Watts
Radeon RX 6800 XT		300 Watts
	Difference: 190 Watts (173%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 XT should be 507% faster than the GeForce GTX 650 Ti 2GB in general, because of its higher bandwidth. (explain)

Radeon RX 6800 XT		524288 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 437888 (507%)

Texel Rate

The Radeon RX 6800 XT should be quite a bit (about 785%) faster with regards to AF than the GeForce GTX 650 Ti 2GB. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 466208 (785%)

Pixel Rate

The Radeon RX 6800 XT is a lot (approximately 1473%) faster with regards to full screen anti-aliasing than the GeForce GTX 650 Ti 2GB, and also should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 218752 (1473%)

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 moved across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher 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 a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
