GeForce GTX 980M vs GeForce RTX 2060

Intro

Compare that to the GeForce RTX 2060, which has clock speeds of 1365 MHz on the GPU, and 1750 MHz on the 6144 MB of GDDR6 RAM. It features 1920 SPUs as well as 120 TAUs and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 980M		100 Watts
GeForce RTX 2060		160 Watts
	Difference: 60 Watts (60%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2060 should be much faster than the GeForce GTX 980M in general. (explain)

GeForce RTX 2060		344064 MB/sec
GeForce GTX 980M		128000 MB/sec
	Difference: 216064 (169%)

Texel Rate

The GeForce RTX 2060 should be quite a bit (about 64%) better at anisotropic filtering than the GeForce GTX 980M. (explain)

GeForce RTX 2060		163800 Mtexels/sec
GeForce GTX 980M		99648 Mtexels/sec
	Difference: 64152 (64%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 980M is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 980M		66432 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 912 (1%)

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 data (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
