Two snippets of Intel news. The chip maker reveals that its upcoming I225 “Foxville” 2.5GbE NICs suffer from an inter-packet gap variance that can result in packet loss and reduced throughput. These controllers will be used by the upcoming Z490 motherboards.

According to Intel, the throughput loss can be 1Mbps to 10Mbps. The same advisory also confirms that a hardware-level fix for the Inter Packet Gap (IPG) issue will be rolled out in the second half of the year. The chip giant says this will align with the production of its future Rocket Lake-S platform, thereby confirming that Rocket Lake-S will launch in the second half of this year.

As VideoCardz reports, it seems one of the key new features of the Z490 could become quite a headache for Intel.
AMD OEMs already offers quite a few X570 motherboards with 2.5 GbE networking, but they rely on 3rd party chipsets. What could have become a feature of the Z490 platform, may end up problematic for Intel. The scope of the problem is still being evaluated by Intel as tests of 3rd party 2.5 GbE networking equipment is in progress.
