GeForce RTX 2060 vs Geforce GTX 780

Intro

Compare all that to the Geforce GTX 780, which comes with core clock speeds of 863 MHz on the GPU, and 1502 MHz on the 3072 MB of GDDR5 RAM. It features 2304 SPUs as well as 192 Texture Address Units and 48 Rasterization Operator Units.

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

Theoretically, the GeForce RTX 2060 should perform a little bit faster than the Geforce GTX 780 overall. (explain)

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

Texel Rate

The Geforce GTX 780 will be a little bit (approximately 1%) more effective at anisotropic 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 high levels of AA is important to you, then the GeForce RTX 2060 is a better choice, by far. (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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, 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 graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
