GeForce GTX 980 vs GeForce RTX 2070 Super

Intro

Compare those specs to the GeForce RTX 2070 Super, which has GPU core speed of 1605 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 256-bit bus. It also is comprised of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

GeForce GTX 980		224000 MB/sec
	Difference: 234752 (105%)

Texel Rate

The GeForce RTX 2070 Super should be a lot (more or less 78%) faster with regards to texture filtering than the GeForce GTX 980. (explain)

GeForce RTX 2070 Super		256800 Mtexels/sec
GeForce GTX 980		144128 Mtexels/sec
	Difference: 112672 (78%)

Pixel Rate

The GeForce RTX 2070 Super will be quite a bit (about 43%) more effective at FSAA than the GeForce GTX 980, and also able to handle higher screen resolutions better. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
GeForce GTX 980		72064 Mpixels/sec
	Difference: 30656 (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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
