GeForce RTX 2080 vs Nvidia Titan X

Intro

The GeForce RTX 2080 has clock speeds of 1515 MHz on the GPU, and 14 MHz on the 8192 MB of GDDR6 memory. It features 2944 SPUs as well as 184 TAUs and 64 ROPs.

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

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 should be 7% quicker than the GeForce RTX 2080 overall, due to its greater bandwidth. (explain)

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

Texel Rate

The Nvidia Titan X is a little bit (about 14%) more effective at texture 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 superior to the GeForce RTX 2080, by far. (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.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card by the core clock 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 applied per second.

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