GeForce RTX 2080 SUPER vs Geforce GTX 770

Intro

Compare those specs to the Geforce GTX 770, which uses a 28 nm design. nVidia has set the core speed at 1046 MHz. The GDDR5 RAM is set to run at a frequency of 1753 MHz on this specific model. It features 1536 SPUs along with 128 Texture Address Units and 32 ROPs.

Geforce GTX 770		230 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 20 Watts (9%)

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER should perform much faster than the Geforce GTX 770 in general. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Geforce GTX 770		224384 MB/sec
	Difference: 283520 (126%)

Texel Rate

The GeForce RTX 2080 SUPER should be a lot (more or less 137%) more effective at anisotropic filtering than the Geforce GTX 770. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 182912 (137%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is superior to the Geforce GTX 770, by far. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 72128 (215%)

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 (measured in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many 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.
