Marvell Technology has launched the Teralynx 102T, a networking switch capable of 102.4 terabits per second of bandwidth. That's enough throughput to transfer roughly 12,800 copies of a 4K Blu-ray movie every second.
The device is the industry's first monolithic die purpose-built for scale-up switching in AI data centers. It doubles the bandwidth of Marvell's previous Teralynx generation, which topped out at 51.2 Tbps and is already in volume production for AI cloud deployments.
The Teralynx 102T features 64 ports running at 1.6 TbE each, with ultra-low latency and high thermal efficiency. Marvell built the entire switch on a single silicon die, which yields lower latency and simpler integration, though with manufacturing complexities.
The company is also emphasizing compatibility with SONiC, the open-source network operating system from Microsoft widely adopted by hyperscale data centers.
Marvell's main competitor is Broadcom, whose Tomahawk 6 series already offers identical 102.4 Tbps throughput and has begun production shipping. Broadcom has deep relationships with hyperscalers like Amazon, Google, and Microsoft.
For investors, Marvell's move signals the bandwidth arms race in AI networking is doubling roughly each generation. Key risks include execution against Broadcom's head start. Investors should watch for design win announcements from major cloud providers.
