GeForce RTX 2080 SUPER vs Geforce GTX 780

Intro

Compare all that to the Geforce GTX 780, which features core clock speeds of 863 MHz on the GPU, and 1502 MHz on the 3072 MB of GDDR5 RAM. It features 2304 SPUs along with 192 Texture Address Units and 48 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER should be 76% faster than the Geforce GTX 780 in general, because of its greater bandwidth. (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 a lot (about 91%) more effective at 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 a high screen resolution is important to you, then the GeForce RTX 2080 SUPER is the winner, by a large margin. (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: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
