Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 965M		60 Watts
GeForce RTX 3080 12 GB		350 Watts
	Difference: 290 Watts (483%)

Memory Bandwidth

In theory, the GeForce RTX 3080 12 GB will be 1360% quicker than the GeForce GTX 965M in general, because of its greater data rate. (explain)

GeForce RTX 3080 12 GB		934298 MB/sec
GeForce GTX 965M		64000 MB/sec
	Difference: 870298 (1360%)

Texel Rate

The GeForce RTX 3080 12 GB should be a lot (more or less 484%) more effective at texture filtering than the GeForce GTX 965M. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
GeForce GTX 965M		60416 Mtexels/sec
	Difference: 292384 (484%)

Pixel Rate

The GeForce RTX 3080 12 GB will be quite a bit (more or less 367%) faster with regards to AA than the GeForce GTX 965M, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
GeForce GTX 965M		30208 Mpixels/sec
	Difference: 110912 (367%)

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 data (measured in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
