The Intel® Ethernet Network Adapter I226-T1 is ideally suited for personal computers and workstations used for enterprise, gaming, and home networks. These systems require more bandwidth than ever before. This ultra-compact, easy-to-integrate PCIe 3.1 x1 adapter, is a cost-effective networking solution for speeds up to 2.5GbE. The I226-T1 is also designed with a ventilated bracket, for increased efficiency and reduced power consumption.
Packed with performance optimization capabilities, the I226-T1 includes advanced interrupt-handling features to reduce CPU overhead. Combining interrupt-handling features with intelligent filtering, ordering, and directing packets to specific queues and cores, enables load-balancing network traffic flows to improve throughput in multi-core platforms.
Based on the Intel® Ethernet Controller I226-LM, this versatile networking solution supports 2.5Gbps, 1Gbps, 100Mbps and 10Mbps network speeds without the need to overhaul existing cabling infrastructure. Simplifying technology transitions with autonegotiation between port speeds provides maximum flexibility.
