GeForce GTX 1630 vs GeForce GTX 650 Ti 2GB

Intro

Compare those specs to the GeForce GTX 650 Ti 2GB, which has a GPU core clock speed of 928 MHz, and 2048 MB of GDDR5 RAM set to run at 1350 MHz through a 128-bit bus. It also is made up of 768 Stream Processors, 64 TAUs, and 16 ROPs.

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1630 should be a small bit faster than the GeForce GTX 650 Ti 2GB overall. (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 small 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 is a lot (more or less 88%) more effective at anti-aliasing than the GeForce GTX 650 Ti 2GB, and should be able to handle 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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be applied in one second. This number is calculated 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
