GeForce RTX 2080 SUPER vs Geforce GTX 770

Intro

Compare all that to the Geforce GTX 770, which has a clock frequency of 1046 MHz and a GDDR5 memory speed of 1753 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1536 SPUs, 128 TAUs, and 32 ROPs.

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

In theory, the GeForce RTX 2080 SUPER will be 126% quicker than the Geforce GTX 770 overall, because of its greater bandwidth. (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 much (more or less 137%) faster with regards to 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 resolution is important to you, then the GeForce RTX 2080 SUPER is a better choice, and very much so. (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 information (in units of megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can 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 Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
