GeForce RTX 2070 Super vs Geforce GTX 770

Intro

Compare that to the Geforce GTX 770, which features GPU clock speed of 1046 MHz, and 2048 MB of GDDR5 memory set to run at 1753 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

GeForce RTX 2070 Super		215 Watts
Geforce GTX 770		230 Watts
	Difference: 15 Watts (7%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2070 Super should be 104% faster than the Geforce GTX 770 overall, due to its greater bandwidth. (explain)

GeForce RTX 2070 Super		458752 MB/sec
Geforce GTX 770		224384 MB/sec
	Difference: 234368 (104%)

Texel Rate

The GeForce RTX 2070 Super is much (approximately 92%) faster with regards to AF than the Geforce GTX 770. (explain)

GeForce RTX 2070 Super		256800 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 122912 (92%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 2070 Super is a better choice, and very much so. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 69248 (207%)

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 (in units of MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
