GeForce RTX 2060 vs Geforce GTX 690

Intro

Compare all of that to the Geforce GTX 690, which has clock speeds of 915 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
Geforce GTX 690		300 Watts
	Difference: 140 Watts (88%)

Memory Bandwidth

In theory, the Geforce GTX 690 should be 12% quicker than the GeForce RTX 2060 overall, because of its greater data rate. (explain)

Geforce GTX 690		384512 MB/sec
GeForce RTX 2060		344064 MB/sec
	Difference: 40448 (12%)

Texel Rate

The Geforce GTX 690 is a lot (about 43%) faster with regards to anisotropic filtering than the GeForce RTX 2060. (explain)

Geforce GTX 690		234240 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 70440 (43%)

Pixel Rate

The GeForce RTX 2060 is a small bit (more or less 12%) more effective at AA than the Geforce GTX 690, and capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 2060		65520 Mpixels/sec
Geforce GTX 690		58560 Mpixels/sec
	Difference: 6960 (12%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
