E1 SoC set to deliver performance and flexibility to address evolving AI and Compute workloads at the lowest CapEx and OpEx
Xsight Labs, a leading fabless semiconductor company providing end-to-end connectivity solutions for next-generation hyperscale, edge, and AI data center networks, today announced the tape-out of the E1, the first SoC in its SDN DPU (Software Defined Networking Data Processing Unit) product family of fully programmable network accelerators. Built on TSMC’s advanced 5nm process technology, the E1 offers unprecedented power efficiency and compute capabilities, setting a new standard in DPU SoC performance. The E1 SoC will be available to customers in early Q2 2025 in multiple evaluation form factors, including PCIe Add-in Cards, one RU appliance and modular system backplane configurations.
Designed for Next-Generation AI Data Centers
The E1’s revolutionary design meets the growing demands of rapidly scaling data center infrastructure and advanced applications, particularly in AI and compute-intensive environments. As evolving AI and HPC workloads place significant strain on CPU resources and require high network throughput, the E1 is an ideal solution, perfectly suited for initiatives like the Ultra Ethernet Consortium (UEC), reliable system interoperability, and running a high-performance software stack. It addresses scaling challenges by offering best-in-class software-defined networking, storage, and security acceleration. Purpose-built for multi-tenant, cloud-native environments, the E1 delivers hardware-accelerated networking and management services at data-center scale, optimizing performance across the most demanding workloads.
Transforming Cloud Infrastructure for the Future
“Modern cloud workloads are redefining hyperscale data center architectures,” said Yossi Meyouhas, CEO of Xsight Labs. “There is a critical need for processors that can offload and accelerate the massive compute demands of virtualization, networking, storage and security. The E1 SoC is designed to meet these challenges head-on, allowing data centers to scale effectively and support the increasing bandwidth and security demands driven by AI workloads.”
Security, Performance, and Scalability
The E1 redefines traditional network infrastructure by creating isolated and secure environments that authenticate every data center user. By offloading and isolating infrastructure services from business applications, the E1 enhances both security and efficiency — from cloud to core to edge. Dual 400G (800G) Ethernet network interfaces deliver an unmatched total throughput of 800Gbps. The E1 is powered by 64 ARM Neoverse N2 cores, advanced DDR5 interfaces, and cutting-edge acceleration for RDMA, cryptography, networking and storage. Additionally, the E1 supports 40 PCIe 5.0 lanes, providing industry-leading I/O throughput connectivity to host CPUs, SSDs, and other devices.
