GeForce GTX 980 vs GeForce RTX 3080 Ti

Intro

Compare all of that to the GeForce RTX 3080 Ti, which features GPU core speed of 1365 MHz, and 12288 MB of GDDR6X RAM running at 1188 MHz through a 384-bit bus. It also features 10240 Stream Processors, 320 TAUs, and 112 ROPs.

GeForce GTX 980		224000 MB/sec
	Difference: 710297 (317%)

Texel Rate

The GeForce RTX 3080 Ti should be quite a bit (approximately 203%) faster with regards to texture filtering than the GeForce GTX 980. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce GTX 980		144128 Mtexels/sec
	Difference: 292672 (203%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 3080 Ti is superior to the GeForce GTX 980, by far. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce GTX 980		72064 Mpixels/sec
	Difference: 80816 (112%)

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 (measured in MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
