GeForce GTX 1650 vs GeForce RTX 2080 Ti

Intro

Compare all of that to the GeForce RTX 2080 Ti, which features GPU core speed of 1350 MHz, and 11264 MB of GDDR6 RAM running at 1750 MHz through a 352-bit bus. It also is made up of 4352 Stream Processors, 272 TAUs, and 88 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
GeForce RTX 2080 Ti		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

In theory, the GeForce RTX 2080 Ti should be 381% quicker than the GeForce GTX 1650 overall, because of its higher bandwidth. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 499712 (381%)

Texel Rate

The GeForce RTX 2080 Ti is quite a bit (more or less 342%) faster with regards to texture filtering than the GeForce GTX 1650. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 284040 (342%)

Pixel Rate

The GeForce RTX 2080 Ti should be much (about 150%) more effective at anti-aliasing than the GeForce GTX 1650, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
GeForce GTX 1650		47520 Mpixels/sec
	Difference: 71280 (150%)

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 max amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
