Texel Rate

The GeForce RTX 3060 is much (more or less 499%) faster with regards to anisotropic filtering than the GeForce 840M. (explain)

GeForce RTX 3060		147840 Mtexels/sec
GeForce 840M		24696 Mtexels/sec
	Difference: 123144 (499%)

Pixel Rate

The GeForce RTX 3060 should be a lot (more or less 670%) faster with regards to anti-aliasing than the GeForce 840M, and will be capable of handling higher resolutions better. (explain)

GeForce RTX 3060		63360 Mpixels/sec
GeForce 840M		8232 Mpixels/sec
	Difference: 55128 (670%)

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 (counted in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
