Nvidia Titan X vs Radeon Pro Duo

Intro

Compare those specifications to the Radeon Pro Duo, which has a GPU core clock speed of 1000 MHz, and 4096 MB of HBM RAM running at 500 MHz through a 4096-bit bus. It also features 4096 Stream Processors, 256 Texture Address Units, and 64 Raster Operation Units.

Radeon Pro Duo		350 Watts
	Difference: 100 Watts (40%)

Memory Bandwidth

Theoretically, the Radeon Pro Duo should be a lot 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 is much (approximately 61%) faster with regards to 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

The Nvidia Titan X will be a bit (approximately 6%) faster with regards to FSAA than the Radeon Pro Duo, and should be able to handle higher screen resolutions more effectively. (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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
