Nvidia Titan X vs Radeon Pro Duo

Intro

Compare that to the Radeon Pro Duo, which features core speeds of 1000 MHz on the GPU, and 500 MHz on the 4096 MB of HBM memory. It features 4096 SPUs along with 256 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Nvidia Titan X		250 Watts
Radeon Pro Duo		350 Watts
	Difference: 100 Watts (40%)

Memory Bandwidth

The Radeon Pro Duo should in theory perform much faster than the Nvidia Titan X overall. (explain)

Radeon Pro Duo		1024000 MB/sec
Nvidia Titan X		491520 MB/sec
	Difference: 532480 (108%)

Texel Rate

The Radeon Pro Duo should be much (more or less 61%) more effective at anisotropic filtering than the Nvidia Titan X. (explain)

Radeon Pro Duo		512000 Mtexels/sec
Nvidia Titan X		317408 Mtexels/sec
	Difference: 194592 (61%)

Pixel Rate

If running with high levels of AA is important to you, then the Nvidia Titan X is superior to the Radeon Pro Duo, but only just. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon Pro Duo		128000 Mpixels/sec
	Difference: 8032 (6%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units 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 processed per second.

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