Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTX 650 Ti 2GB		110 Watts
	Difference: 35 Watts (47%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1630 will be 14% faster than the GeForce GTX 650 Ti 2GB in general, because of its greater bandwidth. (explain)

GeForce GTX 1630		98304 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 11904 (14%)

Texel Rate

The GeForce GTX 650 Ti 2GB will be a bit (about 7%) better at anisotropic filtering than the GeForce GTX 1630. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 3712 (7%)

Pixel Rate

The GeForce GTX 1630 should be a lot (approximately 88%) better at AA than the GeForce GTX 650 Ti 2GB, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 12992 (88%)

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 information (measured in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
