GeForce GTX 980 Ti vs GeForce RTX 2060

Intro

Compare all that to the GeForce RTX 2060, which makes use of a 12 nm design. nVidia has set the core speed at 1365 MHz. The GDDR6 memory works at a speed of 1750 MHz on this model. It features 1920 SPUs along with 120 TAUs and 48 Rasterization Operator Units.

GeForce RTX 2060		160 Watts
GeForce GTX 980 Ti		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

Performance-wise, the GeForce RTX 2060 should theoretically be a bit superior to the GeForce GTX 980 Ti overall. (explain)

GeForce RTX 2060		344064 MB/sec
GeForce GTX 980 Ti		336000 MB/sec
	Difference: 8064 (2%)

Texel Rate

The GeForce GTX 980 Ti will be a bit (approximately 7%) faster with regards to anisotropic filtering than the GeForce RTX 2060. (explain)

GeForce GTX 980 Ti		176000 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 12200 (7%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 980 Ti is the winner, by far. (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 (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 ability to reach the max fill rate.
