Comet Lake-S will have a much larger arrival than previously anticipated. If you have a hard time against AMD and Zen 2, mistakes like the ones we will see below can be very expensive due to the bad reputation they often bring, what happens?
Intel i225 Foxville network cards have a design flaw
Generally a network card component is so fragile and requires precision that it passes high performance and quality checks to make sure everything is working properly. In the case of Intel, its Ethernet cards are so good that they end up weighing the middle and upper market of other manufacturers, since many are included in the series Motherboards.
Or distance i225 Foxville Intel is already being distributed on some motherboards (especially the server), a blue giant that will make them available to more users thanks to the new Comet Lake-S platform under the Z490 chip.
The problem is that the same company has had to issue an internal statement as the official notification of this network's 2.5 Gbps card to its OEM PC and to road board partners. Although it is not a security problem as it is, it does happen depending on the functionality of these systems on all the systems and the configuration of certain types of routers.
Packet loss due to IPG error
Currently there are only two types of i225 on the market or ready to be: i225-V and i225-LM, both cards are affected by what we will describe below. According to Intel's notice, the difference is Inter-packer GAP (IGP), the time between the packets of data transmitted by the card layer, when due to this variability the card may lose data packets, which affect performance.
It is possible that not in all cases this happens, which makes the problem more straightforward. And that's what Intel has confirmed when the card joined PHY 2.5 GbE for Netgear, Juniper and AQuantia The problem arises, and in Cisco, Huawei, Buffalo and Aruba no
At the moment the company is continuing to test different configurations with many products and models to determine the magnitude of the problem, but in any case, we are convinced that no reduction is possible for obvious reasons. The only solution is to configure the network card as 1 GbE on a compatible driver and even though it's already running on a new version of this card, it won't see the light until the second half of this year.
In other words, all motherboards will be released after the release of Comet Lake-S and only for a year and Rocket Lake-S (hopefully not by early 2021) will have this problem solved.
