Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti		110 Watts
GeForce RTX 3080 12 GB		350 Watts
	Difference: 240 Watts (218%)

Memory Bandwidth

In theory, the GeForce RTX 3080 12 GB should be 981% faster than the GeForce GTX 650 Ti overall, because of its higher data rate. (explain)

GeForce RTX 3080 12 GB		934298 MB/sec
GeForce GTX 650 Ti		86400 MB/sec
	Difference: 847898 (981%)

Texel Rate

The GeForce RTX 3080 12 GB is a lot (more or less 494%) faster with regards to texture filtering than the GeForce GTX 650 Ti. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
GeForce GTX 650 Ti		59392 Mtexels/sec
	Difference: 293408 (494%)

Pixel Rate

The GeForce RTX 3080 12 GB is quite a bit (about 850%) more effective at anti-aliasing than the GeForce GTX 650 Ti, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 126272 (850%)

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 largest amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
