Nvidia Titan X vs Radeon RX 6900 XT

Intro

The Nvidia Titan X makes use of a 16 nm design. nVidia has set the core frequency at 1417 MHz. The GDDR5X memory runs at a speed of 1251 MHz on this model. It features 3584 SPUs along with 224 Texture Address Units and 96 Rasterization Operator Units.

Compare those specifications to the Radeon RX 6900 XT, which uses a 7 nm design. AMD has clocked the core frequency at 1825 MHz. The GDDR6 memory works at a speed of 2000 MHz on this specific model. It features 5120 SPUs along with 320 TAUs and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Nvidia Titan X 250 Watts
Radeon RX 6900 XT 300 Watts
Difference: 50 Watts (20%)

Memory Bandwidth

In theory, the Radeon RX 6900 XT will be 7% faster than the Nvidia Titan X in general, because of its greater bandwidth. (explain)

Radeon RX 6900 XT 524288 MB/sec
Nvidia Titan X 491520 MB/sec
Difference: 32768 (7%)

Texel Rate

The Radeon RX 6900 XT will be much (approximately 84%) more effective at texture filtering than the Nvidia Titan X. (explain)

Radeon RX 6900 XT 584000 Mtexels/sec
Nvidia Titan X 317408 Mtexels/sec
Difference: 266592 (84%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6900 XT is a better choice, by far. (explain)

Radeon RX 6900 XT 233600 Mpixels/sec
Nvidia Titan X 136032 Mpixels/sec
Difference: 97568 (72%)

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 transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant 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.
