Nvidia Titan X vs Radeon RX Vega 64

Intro

Compare all that to the Radeon RX Vega 64, which has core 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 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, the Radeon RX Vega 64 should perform just a bit faster than the Nvidia Titan X overall. (explain)

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

Texel Rate

The Radeon RX Vega 64 is a bit (about 1%) better 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

If running with a high screen resolution is important to you, then the Nvidia Titan X is the winner, by far. (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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
