GeForce RTX 2080 vs GeForce RTX 3080

Intro

Compare all of that to the GeForce RTX 3080, which has core speeds of 1440 MHz on the GPU, and 1188 MHz on the 10240 MB of GDDR6X RAM. It features 8704 SPUs as well as 272 Texture Address Units and 96 ROPs.

GeForce RTX 2080		215 Watts
GeForce RTX 3080		320 Watts
	Difference: 105 Watts (49%)

Memory Bandwidth

In theory, the GeForce RTX 3080 is 70% quicker than the GeForce RTX 2080 in general, because of its greater bandwidth. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce RTX 2080		458752 MB/sec
	Difference: 319795 (70%)

Texel Rate

The GeForce RTX 3080 is much (more or less 41%) better at AF than the GeForce RTX 2080. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce RTX 2080		278760 Mtexels/sec
	Difference: 112920 (41%)

Pixel Rate

The GeForce RTX 3080 should be much (about 43%) better at AA than the GeForce RTX 2080, and also should be capable of handling higher resolutions better. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 41280 (43%)

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 (counted in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
