GeForce RTX 2080 vs GeForce RTX 3060

Intro

Compare those specifications to the GeForce RTX 3060, which has a GPU core clock speed of 1320 MHz, and (Unknown) MB of GDDR6 RAM running at 1875 MHz through a 192-bit bus. It also is made up of 3584 SPUs, 112 Texture Address Units, and 48 ROPs.

Texel Rate

The GeForce RTX 2080 will be quite a bit (more or less 89%) faster with regards to texture filtering than the GeForce RTX 3060. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce RTX 3060		147840 Mtexels/sec
	Difference: 130920 (89%)

Pixel Rate

The GeForce RTX 2080 should be a lot (approximately 53%) faster with regards to full screen anti-aliasing than the GeForce RTX 3060, and will be able to handle higher resolutions without slowing down too much. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce RTX 3060		63360 Mpixels/sec
	Difference: 33600 (53%)

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 (in units of MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock 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 fill 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 get to the max fill rate.
