Ethernet Switch Chips are Now Infected with AI: Broadcom Announces Trident 5-X12

Artificial intelligence has been a hot topic this year, and everything is now an AI processor, from CPUs to GPUs, NPUs, and many others. However, it was only a matter of time before we saw an integration of AI processing elements into the networking chips. Today, Broadcom announced its new Ethernet switching silicon called Trident 5-X12. The Trident 5-X12 delivers 16 Tb/s of bandwidth, double that of the previous Trident generation while adding support for fast 800G ports for connection to Tomahawk 5 spine switch chips. The 5-X12 is software-upgradable and optimized for dense 1RU top-of-rack designs, enabling configurations with up to 48x200G downstream server ports and 8x800G upstream fabric ports. The 800G support is added using 100G-PAM4 SerDes, which enables up to 4 m DAC and linear optics.

However, this is not only a switch chip on its own. Broadcom has added AI processing elements in an inference engine called NetGNT (Networking General-purpose Neural-network Traffic-analyzer). It can detect common traffic patterns and optimize data movement across the chip. Specifically, the company has listed an example of the system doing AI/ML workloads. In that case, NetGNT performs intelligent traffic analysis to avoid network congestion in these workloads. For example, it can detect the so-called "incast" patterns in real-time, where many flows converge simultaneously on the same port. By recognizing the start of incast early, NetGNT can invoke hardware-based congestion control techniques to prevent performance degradation without added latency.

Designed mainly for the data center, the Molex 224G product portfolio includes next-generation cables, backplanes, board-to-board connectors, and near-ASIC connector-to-cable solutions. Running at 224 Gbps speeds, these products use PAM4 signaling and boast with " highest levels of electrical, mechanical, physical and signal integrity." As the company states, future high-performance computing (HPC) data centers require a lot of board-to-board, chip-to-chip, and other types of communication to improve overall efficiency and remove bottlenecks in data transfer. To tackle this problem, Molex has a range of products, including Mirror Mezz Enhanced, Inception, and CX2 Dual Speed products.

Future generative AI, 1.6T (1.6 Tb/s) Ethernet, and other data center challenges need a dedicated communication standard, which Molex is aiming to provide. Working with various data center and enterprise customers, the company claims to have set the pace for products based on this 224G PAM4 chip-to-chip technology. We suspect that Open Compute Project (OCP) will be first in the line of adoption, ad Molex has historically worked with them as they adopted Mirror Mezz and Mirror Mezz Pro board-to-board connectors. The new products can be seen below, and we expect to hear more announcements from Molex's partners. Solutions like OSFP 1600, QSFP 800, and QSFP-DD 1600 already use 224G products.
