GeForce RTX 2060 vs Geforce GTX 780

Intro

Compare all of that to the Geforce GTX 780, which uses a 28 nm design. nVidia has set the core frequency at 863 MHz. The GDDR5 memory works at a speed of 1502 MHz on this specific card. It features 2304 SPUs as well as 192 TAUs and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
Geforce GTX 780		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

In theory, the GeForce RTX 2060 should be 19% faster than the Geforce GTX 780 overall, because of its greater data rate. (explain)

GeForce RTX 2060		344064 MB/sec
Geforce GTX 780		288384 MB/sec
	Difference: 55680 (19%)

Texel Rate

The Geforce GTX 780 is just a bit (more or less 1%) more effective at texture filtering than the GeForce RTX 2060. (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 1896 (1%)

Pixel Rate

If using a high screen 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 780		41424 Mpixels/sec
	Difference: 24096 (58%)

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 largest amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must 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 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 calculated 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video 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 number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
