Movidius Myriad X - Perception and Analysis Center

The company Movidius , a subsidiary of Intel, continues to supply us with news from the field of artificial intelligence, computer vision and neural networks. Just a month ago, we discussed the Movidius Neural Compute Stick - “artificial intelligence on a flash drive” based on Myriad 2’s own SoC. And now a new generation of specialized processors has been announced - Movidius Myriad X. According to the company, both generations of SoC will be sold in parallel, while the difference in their performance characteristics is significant; for example, the performance in modeling neural networks increased 10 times and amounted to 1 Teraflops.

The maximum theoretical performance of the Movidius Myriad X is 4 Teraflops, while the power consumption of the SoC remains the same - no more than 1 watt. Compared to its predecessor, the novelty has received an additional four vector 128-bit VLIW-cores SHAVE (Streaming Hybrid Architecture Vector Engine) - now there are 16. There are more accelerators of image and video processing. Myriad X has hardware support for 4k video encoding at speeds up to 60 fps.

Noy SoC is made on 16-nm FinFET technology. It turns out that the technical process has almost halved, which, according to experts, played a major role in a sharp increase in productivity. Other characteristics in comparison with the predecessor can be seen in the table below. As you can see, improvements are observed "on all fronts": faster memory, an increased number of high-speed interfaces, etc.
