Nvidia Titan X vs Radeon RX 6800

Intro

The Nvidia Titan X has a GPU clock speed of 1417 MHz, and the 12288 MB of GDDR5X memory runs at 1251 MHz through a 384-bit bus. It also is made up of 3584 Stream Processors, 224 Texture Address Units, and 96 Raster Operation Units.

Compare those specifications to the Radeon RX 6800, which comes with GPU core speed of 1700 MHz, and 16384 MB of GDDR6 RAM running at 2000 MHz through a 256-bit bus. It also is made up of 3840 Stream Processors, 240 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 should be 7% quicker than the Nvidia Titan X overall, due to its higher bandwidth. (explain)

Radeon RX 6800 524288 MB/sec
Nvidia Titan X 491520 MB/sec
Difference: 32768 (7%)

Texel Rate

The Radeon RX 6800 is a lot (more or less 29%) faster with regards to anisotropic filtering than the Nvidia Titan X. (explain)

Radeon RX 6800 408000 Mtexels/sec
Nvidia Titan X 317408 Mtexels/sec
Difference: 90592 (29%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6800 is the winner, though only just barely. (explain)

Radeon RX 6800 163200 Mpixels/sec
Nvidia Titan X 136032 Mpixels/sec
Difference: 27168 (20%)

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 max amount of information (measured in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
