GeForce GTX 980 vs GeForce RTX 2080 SUPER

Intro

Compare all that to the GeForce RTX 2080 SUPER, which uses a 12 nm design. nVidia has clocked the core frequency at 1650 MHz. The GDDR6 memory is set to run at a speed of 1937 MHz on this model. It features 3072 SPUs as well as 192 TAUs and 64 Rasterization Operator Units.

Texel Rate

The GeForce RTX 2080 SUPER is quite a bit (more or less 120%) more effective at AF than the GeForce GTX 980. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 980		144128 Mtexels/sec
	Difference: 172672 (120%)

Pixel Rate

The GeForce RTX 2080 SUPER should be much (more or less 47%) more effective at AA than the GeForce GTX 980, and capable of handling higher resolutions more effectively. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 980		72064 Mpixels/sec
	Difference: 33536 (47%)

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 (counted in MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
