GeForce GTX 1630 vs GeForce GTX 650 Ti

Intro

Compare all that to the GeForce GTX 650 Ti, which features a core clock speed of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 768 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

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

Texel Rate

The GeForce GTX 650 Ti should be just a bit (more or less 7%) faster with regards to 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 using a high resolution is important to you, then the GeForce GTX 1630 is a better choice, by a large margin. (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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
