Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
Geforce GTX 780		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

In theory, the Geforce GTX 780 will be 193% faster than the GeForce GTX 1630 in general, due to its greater bandwidth. (explain)

Geforce GTX 780		288384 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 190080 (193%)

Texel Rate

The Geforce GTX 780 should be much (more or less 198%) faster with regards to texture filtering than the GeForce GTX 1630. (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 110016 (198%)

Pixel Rate

The Geforce GTX 780 should be quite a bit (about 49%) better at full screen anti-aliasing than the GeForce GTX 1630, and should be able to handle higher screen resolutions more effectively. (explain)

Geforce GTX 780		41424 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 13584 (49%)

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 max amount of information (counted in MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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