10G Network Card(NIC), Quad RJ-45 Port, X8 Lane, X710-T4 Chip, Compare to Intel FTXL710-BM1

10Gtek's XL710-10G-4T-X8 RJ45 10 Gigabit Ethernet PCI Express server adapters are designed for servers and high-end appliances.
The performance is optimized so that system I/O is not the bottleneck in high-performance networking applications. In addition to managing MAC and PHY Ethernet layer functions, the controller manages PCI Express packet traffic across its transaction, link, and physical/logical layers.
Using hardware acceleration, the controller offloads tasks from the host, such as TCP/UDP/IP checksum calculations and TCP segmentation.
