Nvidia Titan X vs Radeon RX Vega 56

Intro

The Nvidia Titan X uses a 16 nm design. nVidia has set the core frequency at 1417 MHz. The GDDR5X RAM works at a speed of 1251 MHz on this particular card. It features 3584 SPUs along with 224 TAUs and 96 ROPs.

Compare those specifications to the Radeon RX Vega 56, which makes use of a 14 nm design. AMD has set the core speed at 1156 MHz. The HBM2 RAM works at a speed of 1600 MHz on this specific card. It features 3584 SPUs as well as 224 Texture Address Units and 64 ROPs.

Nvidia Titan X 491520 MB/sec
Radeon RX Vega 56 419430 MB/sec
Difference: 72090 (17%)

Texel Rate

The Nvidia Titan X should be much (more or less 23%) more effective at AF than the Radeon RX Vega 56. (explain)

Nvidia Titan X 317408 Mtexels/sec
Radeon RX Vega 56 258944 Mtexels/sec
Difference: 58464 (23%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Nvidia Titan X is superior to the Radeon RX Vega 56, by a large margin. (explain)

Nvidia Titan X 136032 Mpixels/sec
Radeon RX Vega 56 73984 Mpixels/sec
Difference: 62048 (84%)

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 transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
