GeForce RTX 2080 SUPER vs Geforce GTX 770

Intro

Compare those specs to the Geforce GTX 770, which has core speeds of 1046 MHz on the GPU, and 1753 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER should be 126% faster than the Geforce GTX 770 in general, due to its greater data rate. (explain)

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

Texel Rate

The GeForce RTX 2080 SUPER will be quite a bit (more or less 137%) more effective at AF 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 a high screen resolution is important to you, then the GeForce RTX 2080 SUPER is superior to the Geforce GTX 770, by a large margin. (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 max amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units 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 a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
