About Xsight Labs
Xsight Labs is a leading fabless semiconductor company delivering end-to-end
connectivity solutions for cloud service providers, hyperscale data center networks and
edge applications.
The company’s X2 family of fully programmable data center switches, ranging from 3.2T to
12.8T, provide application-optimized switching for top-of-rack deployments, data center
fabrics, high-performance computing (HPC), and AI/ML clusters.
Xsight’s E1 DPU is the world’s first 800G DPU, built around a many-core on-path CPU fabric
and hardware accelerators. Together with a standards-based SW development model, this
architecture delivers industry-leading performance while oUering greater ease-ofprogrammability
compared to traditional DPUs.
Together, these products accelerate the high-performance network solutions of tomorrow.
