Because the adapter hardware can complete data segmentation faster than operating system software, this feature can improve transmission performance. The adapter also uses fewer CPU resources. Severability. If a court holds a provision of this Agreement unenforceable, the court will modify that part to the minimum extent necessary to make that part enforceable or, if necessary, to sever that part. The rest of the provision remains fully enforceable. Enable Jumbo frames only if devices across the network support them and are configured to use the same frame size. When setting up Jumbo Frames on other network devices, be aware that different network devices calculate Jumbo Frame sizes differently. Some devices include the header information in the frame size while others do not. Intel®adapters do not include header information in the frame size. In terms of the Intel X550 vs X540, performance should be about the same but the new card is more efficient. Power usage is stated at up to 13W at 10GbE using dual ports with an average power of 11.2W. This drops in half down to gigabit. The X540TW uses 17.4W (typical) and 9.5W at gigabit so quite a big difference.

In this Aquantia AQTION AQC107 vs INTEL X550-T2 comparison, initially, the tester had issues getting the read speeds of Aquantia to perform anywhere near appropriately. However, by switching the MTU value to 9014 the Aquantia outperformed the Intel slightly. Note: IEEE 802.3bz has been the official ratified standard of 2.5g and 5.0 link speeds for over 5-years now. Is IEEE 802.3bz integrated into an NVM image for X550; if so, which one and where is its release notes that specifically say 802.3bz now supported? Governing Law; Jurisdiction. This Agreement is governed by USA and Delaware law without regard to conflict of laws principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply. Except for claims for misappropriation of trade secrets or breach of confidentiality obligations, all disputes and actions arising out of or related to this Agreement are subject to the exclusive jurisdiction of the state and federal courts in Wilmington, Delaware and you consent to personal jurisdiction in those courts.The biggest issue with testing the performance of a 10 Gigabit Ethernet Card is matching up all the hardware to handle the speeds. While I have reviewed the Xyxel 10GbE switch and 10GbE copper transceivers, I struggled to get full 10-gig speeds. NOTE: Intel admits EEE is unsupported on X550-T2 (despite saying its supported in outdated Docs) here:

Intel's NBASE-T technology can be firmware upgraded to support the emerging IEEE 802.3bz specification." The X550 seems like a logical choice over the X450 with driver support lasting through to 2029, and it uses less power with a more convenient PCIe3x4 connection.Now, where is the Firmware, and what version is that Firmware, to enable the Intel-promised IEEE 802.3bz specification on the X550-AT2 NIC? I wrestled with the idea setting up 10gig without a switch and ran into nothing but problems. Since you do have a switch, you should be ok using that. Enables adapters to generate or respond to flow control frames, which help regulate network traffic. But, to reiterate again: This is IRRELEVANT to my request for the Firmware to support the emerging IEEE 802.3bz specification.
