GeForce GTX 1630 vs GeForce GTX 650 Ti

Intro

Compare all of that to the GeForce GTX 650 Ti, which has GPU core speed of 928 MHz, and 1024 MB of GDDR5 memory set to run at 1350 MHz through a 128-bit bus. It also is made up of 768 Stream Processors, 64 Texture Address Units, and 16 Raster Operation 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

The GeForce GTX 1630 should theoretically perform a small bit faster than the GeForce GTX 650 Ti overall. (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 (more or less 7%) better at AF 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 lots of anti-aliasing is important to you, then the GeForce GTX 1630 is the winner, 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 max amount of information (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, 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 maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
