GeForce GTX 1650 vs GeForce RTX 2080

Intro

Compare all that to the GeForce RTX 2080, which has core clock speeds of 1515 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 2944 SPUs along with 184 Texture Address Units and 64 ROPs.

GeForce GTX 1650		131072 MB/sec
	Difference: 327680 (250%)

Texel Rate

The GeForce RTX 2080 is a lot (about 235%) more effective at texture filtering than the GeForce GTX 1650. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 195600 (235%)

Pixel Rate

The GeForce RTX 2080 will be a lot (more or less 104%) faster with regards to full screen anti-aliasing than the GeForce GTX 1650, and will be able to handle higher resolutions while still performing well. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce GTX 1650		47520 Mpixels/sec
	Difference: 49440 (104%)

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 (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
