➀ Realtek unveils RTL8127, a $10 10GbE network controller with PCIe 4.0 x2 interface, supporting 2.5/5/10 Gbps speeds and low power consumption (1.95W).

➁ The controller integrates error correction (ECC) and self-diagnostic features, targeting motherboards, laptops, and CPE devices, with mass production expected in late 2025.

➂ Adoption barriers remain due to high costs of 10GbE switches ($299+) and CAT6A cables, though demand may drive infrastructure price reductions.
