GeForce GTX 1630 vs GeForce GTX 650

Intro

Compare those specifications to the GeForce GTX 650, which comes with core clock speeds of 1058 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs along with 32 Texture Address Units and 16 ROPs.

GeForce GTX 650		64 Watts
GeForce GTX 1630		75 Watts
	Difference: 11 Watts (17%)

Memory Bandwidth

Theoretically, the GeForce GTX 1630 should be a lot faster than the GeForce GTX 650 overall. (explain)

GeForce GTX 1630		98304 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 18304 (23%)

Texel Rate

The GeForce GTX 1630 should be a lot (about 64%) better at anisotropic filtering than the GeForce GTX 650. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 21824 (64%)

Pixel Rate

If running with a high resolution 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		16928 Mpixels/sec
	Difference: 10912 (64%)

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 max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per 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 core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
