GeForce GTX 1650 vs GeForce RTX 2080

Intro

Compare all that to the GeForce RTX 2080, which comes with GPU clock speed of 1515 MHz, and 8192 MB of GDDR6 RAM set to run at 1750 MHz through a 256-bit bus. It also is made up of 2944 Stream Processors, 184 TAUs, and 64 Raster Operation Units.

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

Texel Rate

The GeForce RTX 2080 is a lot (about 235%) more effective at anisotropic 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 should be much (more or less 104%) more effective at full screen anti-aliasing than the GeForce GTX 1650, and also should be able to handle higher resolutions better. (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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
