GeForce RTX 2060 vs Geforce GTX 780

Intro

Compare those specs to the Geforce GTX 780, which comes with a GPU core clock speed of 863 MHz, and 3072 MB of GDDR5 RAM set to run at 1502 MHz through a 384-bit bus. It also is comprised of 2304 SPUs, 192 TAUs, and 48 Raster Operation Units.

GeForce RTX 2060		160 Watts
Geforce GTX 780		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

Theoretically, the GeForce RTX 2060 should be a little bit faster than the Geforce GTX 780 in general. (explain)

GeForce RTX 2060		344064 MB/sec
Geforce GTX 780		288384 MB/sec
	Difference: 55680 (19%)

Texel Rate

The Geforce GTX 780 should be just a bit (more or less 1%) faster with regards to anisotropic filtering than the GeForce RTX 2060. (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 1896 (1%)

Pixel Rate

The GeForce RTX 2060 will be much (approximately 58%) more effective at anti-aliasing than the Geforce GTX 780, and capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 2060		65520 Mpixels/sec
Geforce GTX 780		41424 Mpixels/sec
	Difference: 24096 (58%)

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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
