GeForce RTX 2080 SUPER vs Geforce GTX 780

Intro

Compare all that to the Geforce GTX 780, which features a clock frequency of 863 MHz and a GDDR5 memory speed of 1502 MHz. It also features a 384-bit bus, and uses a 28 nm design. It features 2304 SPUs, 192 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the GeForce RTX 2080 SUPER should be quite a bit faster than the Geforce GTX 780 overall. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Geforce GTX 780		288384 MB/sec
	Difference: 219520 (76%)

Texel Rate

The GeForce RTX 2080 SUPER should be quite a bit (approximately 91%) faster with regards to texture filtering than the Geforce GTX 780. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Geforce GTX 780		165696 Mtexels/sec
	Difference: 151104 (91%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is the winner, and very much so. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Geforce GTX 780		41424 Mpixels/sec
	Difference: 64176 (155%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 can be applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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