Nvidia Titan X vs Radeon Pro Duo

Intro

The Nvidia Titan X uses a 16 nm design. nVidia has set the core frequency at 1417 MHz. The GDDR5X memory runs at a speed of 1251 MHz on this card. It features 3584 SPUs along with 224 Texture Address Units and 96 ROPs.

Compare all of that to the Radeon Pro Duo, which has a core clock speed of 1000 MHz and a HBM memory frequency of 500 MHz. It also features a 4096-bit memory bus, and makes use of a 28 nm design. It features 4096 SPUs, 256 TAUs, 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

As far as performance goes, the Radeon Pro Duo should theoretically be quite a bit better 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 will be much (approximately 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 using lots of anti-aliasing is important to you, then the Nvidia Titan X is superior to the Radeon Pro Duo, but not by far. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
