GeForce RTX 2080 vs Nvidia Titan X

Intro

Compare all of that to the Nvidia Titan X, which has core speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X memory. It features 3584 SPUs along with 224 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Nvidia Titan X is 7% faster than the GeForce RTX 2080 in general, because of its higher bandwidth. (explain)

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

Texel Rate

The Nvidia Titan X should be a small bit (about 14%) faster with regards to anisotropic filtering than the GeForce RTX 2080. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the Nvidia Titan X is a better choice, by a large margin. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the 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 maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
