Marvell Technology just dropped the Teralynx 102T, a networking switch capable of pushing 102.4 terabits per second of bandwidth. To put that in perspective, that’s enough throughput to transfer roughly 12,800 copies of a 4K Blu-ray movie every single second.
The device is being positioned as the industry’s first monolithic die engineered specifically for scale-up switching in AI data center environments. It doubles the bandwidth of Marvell’s previous Teralynx generation, which topped out at 51.2 Tbps and is already in volume production serving AI cloud deployments.
What the Teralynx 102T actually does
The Teralynx 102T addresses this with 64 ports running at 1.6 TbE each. In English: each individual port can handle 1.6 terabits per second of Ethernet traffic, and there are 64 of them working simultaneously.
Marvell is emphasizing two key selling points beyond raw throughput. The first is ultra-low latency, which matters enormously in scale-up AI clusters where even microsecond delays compound across thousands of nodes. The second is thermal efficiency, a factor that’s become increasingly critical as data center operators wrestle with power consumption and cooling costs that are spiraling alongside AI demand.
