NVIDIA has appear their next generation Xavier SOC at GTC Europe 2022. The latest SOC is function of NVIDIA's Tegra family and will replace the currently available Parker SOC in tardily 2022. Xavier is the get-go product that has been announced, featuring NVIDIA'due south next-generation Volta GPU along with custom ARM cores.

NVIDIA Xavier Tegra SOC Announced - Powered past Volta GPU and Custom ARM64 Cores

Since Parker, NVIDIA has moved their Tegra business concern from gaming and mobility over to automotive and AI markets. This in return has offered NVIDIA room to improve upon the design of their Tegra chips drastically, with the current generation SOC featuring 20 Deep Learning Tera-OPs (DLTOPs). Parker is available on two unlike Drive PX 2 boards, one that can feature discrete GPUs (MXM) and a standalone board with just 1 chip. The former delivers 20 DLTOPs at a rated TDP of 80W, but Xavier is going to alter that.

The Xavier SOC will starting time sampling in Q4 2022, that'southward a long fourth dimension till the availability of the chip. This also indicates that Volta will be shipping in higher-end variants to HPC erstwhile in 2022. Current rumors advise a formal unveiling of the new GPU architecture at GTC 2022. NVIDIA did share some technical details of Xavier at the GTC Europe keynote and they are really interesting.

"This is the greatest SoC effort I accept ever known, and we have been edifice chips for a very long time," Huang said. "Just imagine what an democratic vehicle can do in the nigh future with Xavier."

It looks like Volta based fries will be NVIDIA's virtually efficient products to date. Before we go into details on efficiency, let's accept a look at the specifications. The Xavier SOC is congenital on TSMC'southward 16nm FinFET+ procedure node. The fleck itself will pack a full of 7 Billion transistors. The transistor density puts Xavier in the same league as Pascal GP104 which houses vii.2 Billion transistors on a 314mm^two die. With a refined process and architecture pattern, nosotros could be looking at a die very shut to 300mm².

Xavier Comes With 512 Volta Cores and 8 ARM64 Denver Cores

It comes with 512 CUDA cores that are based on the Volta GPU architecture. This is a substantial scrap as Volta has at present been confirmed to be available in 2022. On the CPU side, the chip boasts 8 Custom ARM64 cores. NVIDIA hasn't mentioned their Denver codename in the slides but since these are custom designed, ARM 64-chip cores, we could be looking at a next - gen Denver blueprint that is however to be disclosed. The chip comes with dual 8K HDR video processors and a super fast, estimator vision accelerator for automotive applications.

Also, NVIDIA mentioned some performance numbers for Xavier. The scrap is said to feature up to 20 DLTOPs worth of performance at a TDP of 20W. This will exist achieved on a single SOC and not a custom board like the Drive PX 2. To put things into perspective, Bulldoze PX 2 delivers 24 DLTOPs worth of functioning at 80W. Furthermore, information technology uses ii Parker SOCs and two discrete GPUs based on the Pascal compages. This is 1 DLTOP (INT8) performance per watt nosotros are looking at and its but a glimpse of the massive power efficiency coming in from the Volta architecture.

The new Xavier SOC sounds similar a massive improvement in performance/watt sector. With Volta being disclosed this early, we are sure that GTC 2022 will bring united states a ton of more information on the compages itself. Equally for the new Drive PX board, expect it to start sampling in late 2022, followed by volume shipment in early 2022.
