Details about nvidia jetson xavier soc, a mini

NVIDIA Jetson Xavier was announced at CES 2018 and was revealed to be the largest SOC to date. We received a handful of details about the Xavier SOC when it was announced, but it appears that much more information has been posted on the Jetson Xavier DevKit page. A mini-PC specially designed for AI, robotics and other specific tasks.

NVIDIA Jetson Xavier devkit coming out in August for $ 1, 299

The first is the design of the devkit itself. The devkit comes in two modules, one is the Jetson Xavier support plate that includes all connectivity options and the other is the Jetson Xavier module itself. When purchasing the kit, we receive the two modules, the cables and the power adapter inside the package. The module measures 100mm x 87mm and 16mm in height. With the support plate, the complete package measures 105mm x 105mm.

NVIDIA mentioned that the Xavier SOC is built on a 12nm TSMC process node and that it houses 9 billion transistors in a 350mm2 array area.

To connect to the motherboard, NVIDIA uses a 699-pin connector that is compatible with all types of high-speed I / O, including PCIe 4.0. This is the first NVIDIA platform to officially support PCIe 4.0 and allows transfer speeds of up to 56 Gb / s, double that of the Jetson Xavier SOC. NVIDIA has also mentioned that the connector is not only designed to support PCIe 4.0, but also future I / O standards and allows compatibility with future Jetson modules.

Specs- wise, Xavier's SOC includes NVIDIA's custom-built Carmel ARM64 CPU, which houses 8 cores in a superscalar architecture. Features such as functional security, dual execution, parity, and ECC are available on the CPU itself. Inside the array there is also a Volta GPU containing 512 CUDA cores. The Volta GPU is capable of FP32, FP16, and INT8 calculations as needed in a multi-precision environment. The chip provides 1.3 FP32 maximum performance TFLOPs and 20 Tensor core TOPs.
