ASMedia Technology Inc. announced that its USB4 device controller, the ASM2464PDX, has achieved Intel Thunderbolt 4 certification. The company framed the milestone as a significant upgrade in its product strategy within the Thunderbolt ecosystem. ASMedia said the certified controller is intended to provide a complete solution for edge Artificial Intelligence computing, professional users, and the high-performance storage market.
The ASM2464PDX is presented as setting a new market standard for downstream port specifications. According to the announcement, the controller is the first to support the PCI Express Gen 4 x4 interface on its downstream port. ASMedia highlighted that this pioneering downstream capability distinguishes the ASM2464PDX from competing controllers and aligns the device with workloads and peripherals that can leverage higher lane counts.
Beyond the downstream interface, ASMedia emphasized bandwidth and storage compatibility. The company said the ASM2464PDX’s specification complements high-end NVMe SSDs and unlocks the full 40 Gbps bandwidth potential of Thunderbolt 4. That unlocking is described as enabling transmission speeds faster than previously available for Thunderbolt 4 solutions, positioning the controller for applications that demand high throughput and low-latency external storage and compute connectivity.
