Nvidia Titan X vs Radeon VII

Intro

The Nvidia Titan X comes with a GPU core clock speed of 1417 MHz, and the 12288 MB of GDDR5X memory runs at 1251 MHz through a 384-bit bus. It also features 3584 SPUs, 224 TAUs, and 96 Raster Operation Units.

Compare those specs to the Radeon VII, which makes use of a 7 nm design. AMD has clocked the core frequency at 1400 MHz. The HBM2 memory is set to run at a frequency of 1000 MHz on this particular card. It features 3840 SPUs along with 240 Texture Address Units and 64 Rasterization Operator Units.

Power Consumption (Max TDP)

Nvidia Titan X 250 Watts
Radeon VII 295 Watts
Difference: 45 Watts (18%)

Memory Bandwidth

In theory, the Radeon VII should be quite a bit faster than the Nvidia Titan X overall. (explain)

Radeon VII 1048576 MB/sec
Nvidia Titan X 491520 MB/sec
Difference: 557056 (113%)

Texel Rate

The Radeon VII is a bit (about 6%) better at texture filtering than the Nvidia Titan X. (explain)

Radeon VII 336000 Mtexels/sec
Nvidia Titan X 317408 Mtexels/sec
Difference: 18592 (6%)

Pixel Rate

If using a high screen resolution is important to you, then the Nvidia Titan X is superior to the Radeon VII, by a large margin. (explain)

Nvidia Titan X 136032 Mpixels/sec
Radeon VII 89600 Mpixels/sec
Difference: 46432 (52%)

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 max amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
