GeForce 920M vs GeForce RTX 2080

Intro

Compare all of that to the GeForce RTX 2080, which makes use of a 12 nm design. nVidia has set the core frequency at 1515 MHz. The GDDR6 memory runs at a speed of 1750 MHz on this model. It features 2944 SPUs as well as 184 TAUs and 64 ROPs.

GeForce 920M		14400 MB/sec
	Difference: 444352 (3086%)

Texel Rate

The GeForce RTX 2080 is a lot (more or less 813%) faster with regards to texture filtering than the GeForce 920M. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 248232 (813%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 2080 is a better choice, by a large margin. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 89328 (1170%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
