This year thanks to inexpensive controllers 2,5 Gb/s Ethernet ports were expected to become mainstream. The 1Gb/s Ethernet standard in home PCs is a little outdated, to say the least. Alas, the new Intel network controllers had , to eliminate which a new version of the crystal will be released. And it will only happen in the fall.
Network sources have distributed a copy of an Intel document allegedly sent to the company's manufacturing partners who produce motherboards. It follows from the document that when working with routers and switches of some companies, the Intel i225 controllers work flawlessly, while when working with others, errors occur.
So, Intel network controllers transmitted packets to active network equipment from Aruba, Buffalo, Cisco and Huawei without any problems. When working with equipment from Aquantia, Juniper and Netgear, some packets were lost, which led to a decrease in data transfer rate to 10 Mbps. According to Intel, there was a defect in the Foxville controllers that caused deviations in the inter-burst interval from the value set in the IEEE 2.5 GBASE-T standard.
Before the release of the new stepping of the Intel i225 “Foxville” controller, the problem with packet loss can be solved manually by configuring the controller to work at 1 Gb / s, which makes it pointless to use 2,5 Gb / s Intel controllers until the problem is resolved.
In addition, the copy of the distributed document does not indicate which of the two Intel i225 "Foxville" controllers was developed with a defect. Apparently, both. One of them is the budget Intel i225-V "Foxville" with a MAC on the motherboard and a unique Intel bus. It was this solution, coupled with the 400-series chipsets and LGA 1200 processors, that promised to make 2,5 Gb / s Ethernet ports a mass phenomenon. The second controller, Intel i211-LM, is relatively more expensive and is intended for use in motherboards with third-party chipsets, such as platforms for AMD processors.
Separately, it can be noted that if the submitted document is genuine, then the company for the first time officially confirmed plans to release 14-nm Rocket Lake-S processors this fall. The corrected network controllers "Foxville" promise to be released at the same time as these intriguing new products from Intel.
