GeForce 940M vs GeForce RTX 3080 12 GB

Intro

Compare all of that to the GeForce RTX 3080 12 GB, which comes with a GPU core clock speed of 1260 MHz, and 12288 MB of GDDR6X memory set to run at 1188 MHz through a 384-bit bus. It also is made up of 8960 Stream Processors, 280 TAUs, and 112 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce RTX 3080 12 GB should theoretically be much faster than the GeForce 940M overall. (explain)

GeForce RTX 3080 12 GB		934298 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 918298 (5739%)

Texel Rate

The GeForce RTX 3080 12 GB is a lot (approximately 1271%) better at anisotropic filtering than the GeForce 940M. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 327072 (1271%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 3080 12 GB is a better choice, by far. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 132544 (1546%)

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 largest amount of information (counted in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
