For years, laptop users chased 10‑gigabit speeds through bulky Thunderbolt adapters. The new WisdPi USB 3.2 Gen 2x2 NIC shrinks the form factor and halves the cost, selling for $80 instead of the $150‑plus price of Thunderbolt equivalents. Its RTL8159 base chip promises 10 Gbps over a single USB‑C port.

Benchmarks show the adapter reaches full throughput only on systems with a true 20‑Gbps USB 3.2 Gen 2x2 port, such as the AMD desktop with a B650 board. On Macs and the Framework laptop, speeds hover around 6–7 Gbps, matching the theoretical limits of their USB 3.1 Gen 2 ports.

Thermal tests reveal the unit stays under 42.5°C during sustained transfer, a stark contrast to larger Aquantia adapters that turn into ovens. Power draw tops out at roughly 0.86 W when operating at USB 2 speed, indicating efficient heat management even under load.

For teams already running a 10 Gbps network and needing a compact, RJ45‑based solution, the WisdPi adapter offers a sensible cost‑benefit over Thunderbolt. If full 10 Gbps is essential, a Thunderbolt or SFP+ card remains preferable; otherwise, 2.5 or 5 Gbps USB options still deliver better value.
