GeForce 825M vs GeForce RTX 3060

Intro

Compare those specifications to the GeForce RTX 3060, which features a core clock speed of 1320 MHz and a GDDR6 memory frequency of 1875 MHz. It also makes use of a 192-bit memory bus, and uses a 8 nm design. It features 3584 SPUs, 112 Texture Address Units, and 48 Raster Operation Units.

GeForce 825M		13600 Mtexels/sec
	Difference: 134240 (987%)

Pixel Rate

The GeForce RTX 3060 is a lot (about 832%) better at FSAA than the GeForce 825M, and should be capable of handling higher screen resolutions more effectively. (explain)

GeForce RTX 3060		63360 Mpixels/sec
GeForce 825M		6800 Mpixels/sec
	Difference: 56560 (832%)

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 data (counted in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. 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, High Dynamic Range and high 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 amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
