GeForce GTX 980 vs GeForce RTX 3080 Ti

Intro

Compare those specifications to the GeForce RTX 3080 Ti, which has GPU clock speed of 1365 MHz, and 12288 MB of GDDR6X RAM running at 1188 MHz through a 384-bit bus. It also features 10240 SPUs, 320 Texture Address Units, and 112 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 980		165 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 185 Watts (112%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 Ti is 317% faster than the GeForce GTX 980 overall, due to its greater data rate. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
GeForce GTX 980		224000 MB/sec
	Difference: 710297 (317%)

Texel Rate

The GeForce RTX 3080 Ti should be quite a bit (about 203%) more effective at anisotropic 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 using a high resolution is important to you, then the GeForce RTX 3080 Ti is superior to the GeForce GTX 980, and very much so. (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 max amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, 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 amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
