ConnectX NICs

10/25/40/50/100/200 and 400G Ethernet Network Adapters

The industry-leading NVIDIA® ConnectX® family of network interface cards (NICs) offers advanced hardware offloads and accelerations. NVIDIA Ethernet adapters enable the highest ROI and lowest total cost of ownership for hyperscale, public and private clouds, storage, machine learning, AI, big data, and telco platforms.

World-Class Ethernet Performance

ConnectX Ethernet NICs offer best-in-class network performance, serving low-latency, high-throughput applications with one, two, or four ports at 10, 25, 40, 50, 100, 200, and up to 400 gigabits per second (Gb/s) Ethernet speeds.

  • ConnectX NICs are powered by NVIDIA ASAP2 Accelerated Switch and Packet Processing™ technology. They accelerate network performance while reducing the CPU overhead of Internet Protocol (IP) packet transport, freeing more processor cycles to run applications.
  • With unmatched remote direct-memory access (RDMA) over Converged Ethernet (RoCE) performance, ConnectX NICs deliver efficient, high-performance RDMA services to bandwidth- and latency-sensitive applications.
  • ConnectX NICs offload and accelerate encryption/decryption at speeds up to 400Gb/s.
  • With industry-leading Data Plane Development Kit (DPDK) performance, they deliver more throughput with fewer CPU cycles.
  • They enable secure boot of the operating system with in-hardware root of trust.
  • With the NVIDIA Multi-Host™ technology, ConnectX NICs enable direct, low-latency data access while significantly improving server density.
  • ConnectX NICS are certified in all major operating systems as well as top virtualization and containerization platforms.


Accelerated Software-Defined Networking

NVIDIA ASAP2 technology built into ConnectX NICs accelerates software-defined networking with no CPU penalty.

Security From Edge to Core

ConnectX NICs provide innovative hardware engines that offload and accelerate security with in-line encryption/decryption.

Enhanced Storage Performance

ConnectX NICs enable high-performance storage and data access with RoCE and GPUDirect® Storage. NVM Express (NVMe) over Transmission Control Protocol (TCP) acceleration is added in ConnectX-7.

Precision Timing

Starting with ConnectX-6 Dx, ConnectX NICs provide an accurate time-synchronization service for data center applications and underlying infrastructure.

Networking for the Era of AI

NVIDIA Ethernet SuperNICs emerge as a new class of network accelerators, purpose-built to supercharge network-intensive, massively distributed AI computing workloads.
