GeForce 820M vs GeForce RTX 3060

Intro

Compare those specifications to the GeForce RTX 3060, which uses a 8 nm design. nVidia has clocked the core speed at 1320 MHz. The GDDR6 memory works at a frequency of 1875 MHz on this model. It features 3584 SPUs along with 112 TAUs and 48 Rasterization Operator Units.

GeForce 820M		16000 MB/sec
	Difference: 352640 (2204%)

Texel Rate

The GeForce RTX 3060 should be quite a bit (more or less 1185%) better at anisotropic filtering than the GeForce 820M. (explain)

GeForce RTX 3060		147840 Mtexels/sec
GeForce 820M		11504 Mtexels/sec
	Difference: 136336 (1185%)

Pixel Rate

The GeForce RTX 3060 will be quite a bit (about 2103%) more effective at FSAA than the GeForce 820M, and also should be capable of handling higher screen resolutions better. (explain)

GeForce RTX 3060		63360 Mpixels/sec
GeForce 820M		2876 Mpixels/sec
	Difference: 60484 (2103%)

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 (counted in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, 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 is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
