GeForce RTX 2060 vs Geforce GTX 770

Intro

Compare all of that to the Geforce GTX 770, which uses a 28 nm design. nVidia has set the core frequency at 1046 MHz. The GDDR5 RAM runs at a frequency of 1753 MHz on this particular card. It features 1536 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

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

The GeForce RTX 2060, in theory, should be a lot faster than the Geforce GTX 770 overall. (explain)

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

Texel Rate

The GeForce RTX 2060 should be quite a bit (more or less 22%) better 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 using a high resolution is important to you, then the GeForce RTX 2060 is a better choice, by far. (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 maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. The number 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 4 instead. 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 number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
