Rivet Networks today formally launched its 2.5 Gbps Killer Ethernet E3100-series NICs targeted at gaming notebooks and motherboards. These 2.5 GbE solutions are based on Intel's i225-series "Foxville" PHY chips. The new E3100G is based on the i225-V, and is targeted at platforms that have chipset-integrated MAC (most Intel chipsets). The E3100X is based on the i225-LM, and has an integrated MAC, making it better suited for gaming notebooks with Ryzen 4000H-series processors. The software side of things is where Rivet's innovations are.

The Killer Prioritization Engine detects network traffic from games and prioritizes it. This should improve latencies when competitive gamers are also streaming on the side. Under extreme network stress (think gaming+streaming+downloads), Rivet claims the tech can improve gaming latencies by up to 3 times. Next up is GameFast tech, an optimized HSP component of the driver that reduces CPU utilization by up to 10% and the network stack's memory footprint by 20%, compared to other 2.5 GbE solutions. Lastly, there's support for DoubleShot Pro, Killer's network teaming tech that lets you combine bandwidth of your wired and wireless network interface for up to 4.9 Gbps bandwidth. The Killer Control Center 2.0 app gives you control over this and the other features.
