Nvidia Titan X vs Radeon Pro Duo

Intro

Compare those specs to the Radeon Pro Duo, which comes with GPU clock speed of 1000 MHz, and 4096 MB of HBM memory running at 500 MHz through a 4096-bit bus. It also is made up of 4096 Stream Processors, 256 Texture Address Units, and 64 Raster Operation Units.

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, in theory, should perform quite a bit faster than the Nvidia Titan X in general. (explain)

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

Texel Rate

The Radeon Pro Duo will be a lot (about 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

The Nvidia Titan X should be a little bit (about 6%) more effective at FSAA than the Radeon Pro Duo, and also should be able to handle higher screen resolutions without slowing down too much. (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: Bandwidth is the largest amount of information (in units of MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
