Nvidia Titan X vs Radeon Pro Duo

Intro

Compare those specs to the Radeon Pro Duo, which features a clock speed of 1000 MHz and a HBM memory frequency of 500 MHz. It also features a 4096-bit bus, and uses a 28 nm design. It is comprised of 4096 SPUs, 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

As far as performance goes, the Radeon Pro Duo should in theory be quite a bit better 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 (approximately 61%) more effective at texture 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 a high screen resolution is important to you, then the Nvidia Titan X is superior to the Radeon Pro Duo, not by a very large margin though. (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 information (in units of megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
