GeForce RTX 2080 vs Nvidia Titan X

Intro

Compare those specifications to the Nvidia Titan X, which features a clock frequency of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also makes use of a 384-bit bus, and uses a 16 nm design. It is comprised of 3584 SPUs, 224 TAUs, and 96 ROPs.

GeForce RTX 2080		215 Watts
Nvidia Titan X		250 Watts
	Difference: 35 Watts (16%)

Memory Bandwidth

Performance-wise, the Nvidia Titan X should theoretically be a bit superior to the GeForce RTX 2080 in general. (explain)

Nvidia Titan X		491520 MB/sec
GeForce RTX 2080		458752 MB/sec
	Difference: 32768 (7%)

Texel Rate

The Nvidia Titan X should be just a bit (about 14%) more effective at AF than the GeForce RTX 2080. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce RTX 2080		278760 Mtexels/sec
	Difference: 38648 (14%)

Pixel Rate

The Nvidia Titan X will be a lot (approximately 40%) better at AA than the GeForce RTX 2080, and also able to handle higher resolutions while still performing well. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 39072 (40%)

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 data (counted in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could 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 Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
