GeForce GTX 1630 vs GeForce GTX 650 Ti

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1630 will be 14% quicker than the GeForce GTX 650 Ti overall, because of its greater bandwidth. (explain)

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

Texel Rate

The GeForce GTX 650 Ti will be just a bit (about 7%) more effective at anisotropic filtering than the GeForce GTX 1630. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1630 is a better choice, and very much so. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 650 Ti		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 maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. It's 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 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
