Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
Geforce GTX 770		230 Watts
	Difference: 70 Watts (44%)

Memory Bandwidth

In theory, the GeForce RTX 2060 will be 53% quicker than the Geforce GTX 770 in general, because of its higher bandwidth. (explain)

GeForce RTX 2060		344064 MB/sec
Geforce GTX 770		224384 MB/sec
	Difference: 119680 (53%)

Texel Rate

The GeForce RTX 2060 is quite a bit (more or less 22%) more effective at AF than the Geforce GTX 770. (explain)

GeForce RTX 2060		163800 Mtexels/sec
Geforce GTX 770		133888 Mtexels/sec
	Difference: 29912 (22%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 2060 is a better choice, by a large margin. (explain)

GeForce RTX 2060		65520 Mpixels/sec
Geforce GTX 770		33472 Mpixels/sec
	Difference: 32048 (96%)

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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 are applied per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

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