GeForce RTX 2080 vs GeForce RTX 3060

Intro

Compare that to the GeForce RTX 3060, which makes use of a 8 nm design. nVidia has set the core speed at 1320 MHz. The GDDR6 memory is set to run at a speed of 1875 MHz on this particular model. It features 3584 SPUs as well as 112 Texture Address Units and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3060		170 Watts
GeForce RTX 2080		215 Watts
	Difference: 45 Watts (26%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 should be 24% quicker than the GeForce RTX 3060 overall, due to its higher data rate. (explain)

GeForce RTX 2080		458752 MB/sec
GeForce RTX 3060		368640 MB/sec
	Difference: 90112 (24%)

Texel Rate

The GeForce RTX 2080 should be quite a bit (about 89%) faster with regards to AF 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 will be much (more or less 53%) more effective at AA than the GeForce RTX 3060, and also should be able to handle higher screen resolutions more effectively. (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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core 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 fill 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 maximum fill rate.
