VS

Nvidia Titan X vs Radeon RX 6900 XT

Intro

The Nvidia Titan X comes with 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 ROPs.

Compare that to the Radeon RX 6900 XT, which features core clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 5120 SPUs along with 320 Texture Address Units and 128 ROPs.

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

Theoretically speaking, the Radeon RX 6900 XT should be 7% quicker than the Nvidia Titan X in general, because of its higher data rate. (explain)

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

Texel Rate

The Radeon RX 6900 XT should be quite a bit (more or less 84%) better at anisotropic 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

The Radeon RX 6900 XT should be quite a bit (more or less 72%) better at AA than the Nvidia Titan X, and also will be able to handle higher resolutions without losing too much performance. (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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
