GeForce GTX 870M vs GeForce RTX 3060

Intro

Compare all of that to the GeForce RTX 3060, which comes with GPU core speed of 1320 MHz, and (Unknown) MB of GDDR6 RAM running at 1875 MHz through a 192-bit bus. It also features 3584 SPUs, 112 Texture Address Units, and 48 ROPs.

GeForce GTX 870M		110 Watts
GeForce RTX 3060		170 Watts
	Difference: 60 Watts (55%)

Memory Bandwidth

In theory, the GeForce RTX 3060 is 284% faster than the GeForce GTX 870M in general, due to its higher bandwidth. (explain)

GeForce RTX 3060		368640 MB/sec
GeForce GTX 870M		96000 MB/sec
	Difference: 272640 (284%)

Texel Rate

The GeForce RTX 3060 will be a lot (about 40%) more effective at AF than the GeForce GTX 870M. (explain)

GeForce RTX 3060		147840 Mtexels/sec
GeForce GTX 870M		105392 Mtexels/sec
	Difference: 42448 (40%)

Pixel Rate

If using a high resolution is important to you, then the GeForce RTX 3060 is superior to the GeForce GTX 870M, by a large margin. (explain)

GeForce RTX 3060		63360 Mpixels/sec
GeForce GTX 870M		22584 Mpixels/sec
	Difference: 40776 (181%)

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 transferred across the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
