Nvidia Titan X vs Radeon RX Vega 64

Intro

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

Compare all of that to the Radeon RX Vega 64, which has core clock speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 RAM. It features 4096 SPUs along with 256 TAUs and 64 ROPs.

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

As far as performance goes, the Radeon RX Vega 64 should in theory be a bit superior to the Nvidia Titan X in general. (explain)

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

Texel Rate

The Radeon RX Vega 64 should be a little bit (about 1%) more effective at texture filtering than the Nvidia Titan X. (explain)

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

Pixel Rate

The Nvidia Titan X will be quite a bit (approximately 70%) faster with regards to full screen anti-aliasing than the Radeon RX Vega 64, and able to handle higher screen resolutions without losing too much performance. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
