GeForce GTX Titan X vs GeForce RTX 3080

Intro

Compare those specifications to the GeForce RTX 3080, which features a clock speed of 1440 MHz and a GDDR6X memory speed of 1188 MHz. It also uses a 320-bit memory bus, and uses a 8 nm design. It is comprised of 8704 SPUs, 272 Texture Address Units, and 96 Raster Operation Units.

GeForce GTX Titan X		336000 MB/sec
	Difference: 442547 (132%)

Texel Rate

The GeForce RTX 3080 is a lot (more or less 104%) better at texture filtering than the GeForce GTX Titan X. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce GTX Titan X		192000 Mtexels/sec
	Difference: 199680 (104%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 3080 is the winner, by a large margin. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce GTX Titan X		96000 Mpixels/sec
	Difference: 42240 (44%)

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 transported across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
