GeForce GTX 880M vs GeForce RTX 3060

Intro

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

GeForce GTX 880M		130 Watts
GeForce RTX 3060		170 Watts
	Difference: 40 Watts (31%)

Memory Bandwidth

Performance-wise, the GeForce RTX 3060 should in theory be much better than the GeForce GTX 880M in general. (explain)

GeForce RTX 3060		368640 MB/sec
GeForce GTX 880M		128000 MB/sec
	Difference: 240640 (188%)

Texel Rate

The GeForce RTX 3060 is a lot (about 21%) better at texture filtering than the GeForce GTX 880M. (explain)

GeForce RTX 3060		147840 Mtexels/sec
GeForce GTX 880M		122112 Mtexels/sec
	Difference: 25728 (21%)

Pixel Rate

The GeForce RTX 3060 is quite a bit (approximately 108%) better at FSAA than the GeForce GTX 880M, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 3060		63360 Mpixels/sec
GeForce GTX 880M		30528 Mpixels/sec
	Difference: 32832 (108%)

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 largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core clock 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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 potential to reach the max fill rate.
