Nvidia Titan X vs Radeon RX Vega 64

Intro

The Nvidia Titan X features core speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X RAM. It features 3584 SPUs along with 224 Texture Address Units and 96 Rasterization Operator Units.

Compare all that to the Radeon RX Vega 64, which comes with core clock speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 memory. It features 4096 SPUs as well as 256 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Nvidia Titan X 250 Watts
Radeon RX Vega 64 295 Watts
Difference: 45 Watts (18%)

Memory Bandwidth

Theoretically speaking, the Radeon RX Vega 64 should be 1% faster than the Nvidia Titan X overall, due to its higher bandwidth. (explain)

Radeon RX Vega 64 495411 MB/sec
Nvidia Titan X 491520 MB/sec
Difference: 3891 (1%)

Texel Rate

The Radeon RX Vega 64 will be a little bit (more or less 1%) better at AF than the Nvidia Titan X. (explain)

Radeon RX Vega 64 319232 Mtexels/sec
Nvidia Titan X 317408 Mtexels/sec
Difference: 1824 (1%)

Pixel Rate

If running with a high screen resolution is important to you, then the Nvidia Titan X is a better choice, and very much so. (explain)

Nvidia Titan X 136032 Mpixels/sec
Radeon RX Vega 64 79808 Mpixels/sec
Difference: 56224 (70%)

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 data (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
