GeForce GTX 1630 vs GeForce GTX 1650

Intro

Compare those specifications to the GeForce GTX 1650, which features a GPU core clock speed of 1485 MHz, and 4096 MB of GDDR5 RAM set to run at 2001 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 1650 is 33% faster than the GeForce GTX 1630 overall, due to its greater bandwidth. (explain)

GeForce GTX 1650		131072 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 32768 (33%)

Texel Rate

The GeForce GTX 1650 should be much (more or less 49%) more effective at AF than the GeForce GTX 1630. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 27480 (49%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1650 is the winner, by far. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 19680 (71%)

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 data (counted in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
