Nvidia Titan X vs Radeon Pro Duo

Intro

Compare those specifications to the Radeon Pro Duo, which features clock 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 Rasterization Operator 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

Theoretically speaking, the Radeon Pro Duo should perform a lot 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 (more or less 61%) more effective at AF 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 just a bit (approximately 6%) more effective at anti-aliasing than the Radeon Pro Duo, and able to handle higher 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 (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should 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 AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
