GeForce GTX 980 Ti vs GeForce RTX 2060

Intro

Compare those specifications to the GeForce RTX 2060, which comes with a clock speed of 1365 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 192-bit memory bus, and uses a 12 nm design. It features 1920 SPUs, 120 TAUs, and 48 ROPs.

GeForce RTX 2060		163800 Mtexels/sec
	Difference: 12200 (7%)

Pixel Rate

The GeForce GTX 980 Ti is much (more or less 47%) better at full screen anti-aliasing than the GeForce RTX 2060, and also able to handle higher resolutions more effectively. (explain)

GeForce GTX 980 Ti		96000 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 30480 (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 max amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core 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 in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
