GeForce GTX 980 vs GeForce RTX 2060

Intro

Compare those specifications to the GeForce RTX 2060, which uses a 12 nm design. nVidia has set the core frequency at 1365 MHz. The GDDR6 RAM is set to run at a speed of 1750 MHz on this card. It features 1920 SPUs as well as 120 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
GeForce GTX 980		165 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2060 should perform quite a bit faster than the GeForce GTX 980 overall. (explain)

GeForce RTX 2060		344064 MB/sec
GeForce GTX 980		224000 MB/sec
	Difference: 120064 (54%)

Texel Rate

The GeForce RTX 2060 is a bit (about 14%) more effective at texture filtering than the GeForce GTX 980. (explain)

GeForce RTX 2060		163800 Mtexels/sec
GeForce GTX 980		144128 Mtexels/sec
	Difference: 19672 (14%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 980 is the winner, though only just barely. (explain)

GeForce GTX 980		72064 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 6544 (10%)

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 maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one 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 video 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 number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
