GeForce GTX 1630 vs GeForce GTX 650 Ti 2GB

Intro

Compare all of that to the GeForce GTX 650 Ti 2GB, which makes use of a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The GDDR5 memory runs at a speed of 1350 MHz on this particular card. It features 768 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

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 14% quicker 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 is a small bit (more or less 7%) better at AF 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 quite a bit (about 88%) better at FSAA than the GeForce GTX 650 Ti 2GB, and also capable of handling higher resolutions without slowing down too much. (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 information (measured in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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.
