Overview

The Intel X710T2LBLK is a dual-port 10 Gigabit Ethernet network adapter from Intel's X710 series. It uses a PCI Express 3.0 x8 interface and provides two RJ-45 ports that auto-negotiate speeds from 100 Mbps up to 10 Gbps. The card ships with both standard and low-profile brackets, making it suitable for full-size towers as well as compact servers and workstations. Designed for data centers and high-end desktops, this adapter delivers stable 10GbE connectivity at a reasonable price point.

Connectivity & Compatibility

Interface: PCI Express 3.0 x8 (physically fits in x16 slots but runs at x8 lanes) Supported speeds: 100BASE-T, 1000BASE-T, 2.5GBASE-T, 5GBASE-T, 10GBASE-T (auto-negotiation) OS support: Windows Server, Linux, VMware ESXi, and desktop Windows with driver installation Brackets included: standard full-height and low-profile * Note: To achieve full 10GbE performance, you need a compatible switch and Cat6a or better cabling. Also ensure your motherboard has a free PCIe 3.0 x8 (or higher) slot with enough lanes.

Product Info

The Intel X710T2LBLK is a retail package product from Intel. It was released around 2020 and remains widely available. Pricing on is approximately ¥49,028 as of July 2026. Intel provides a standard 3-year warranty. The package includes the adapter, standard bracket, low-profile bracket, and a quick-start guide — no additional cables are included. Market positioning sits between mid-range and high-end; it offers lower power consumption than Intel's X550 series and serves as an excellent entry point for 10GBASE-T networking.

Best Use Cases

NAS or file server builders: 10GbE dramatically improves large file transfer speeds, especially in multi-client environments. However, you'll need to invest in a 10GbE switch and appropriate cabling to fully benefit. Video editors and 3D renderers: Editing high-resolution RAW footage or project files directly from a NAS becomes feasible without network bottlenecks. Ensure your workstation's local storage is also fast enough to keep up. Small office / data center administrators: The Intel chipset offers proven stability and broad driver support for long-term deployment. Low power draw (~8W TDP) keeps heat manageable in dense racks. A 10GbE switch or router is required. Home lab enthusiasts: The X710T2LBLK is relatively easy to find on the secondhand market and is great for learning 10GbE networking. Keep in mind that typical home internet connections won't benefit — this is for high-speed local area networks.
