If you're taxing the CPU and USB device bandwidth on the new USB 3.0 ports, you might not get consistent Gbps-range performance, but in my testing so far, the Pi 4 can sustain over 900 Mbps (// I received a shipment of some Raspberry Pi 2 model B computers for a project I'm working on (more on that to come!), and as part of my project, I've been performing a ton of benchmarks on every aspect of the 2, B+, and A+ Pis I have on hand-CPU, disk (microSD), external SSD, external HDD, memory, and networking. Note about model 4: The Raspberry Pi 4 model B finally has true Gigabit wired LAN, owing to it's new I/O architecture. So if you have a 3 B+, there's no need to buy an external USB Gigabit adapter if you want to max out the wired networking speed! Note about model 3 B+: The Raspberry Pi 3 model B+ includes a Gigabit wired LAN adapter onboard-though it's still hampered by the USB 2.0 bus speed (so in real world use you get ~224 Mbps instead of ~950 Mbps).
Linux Kernel 2.6.Tl dr You can get Gigabit networking working on any current Raspberry Pi (A+, B+, Pi 2 model B, Pi 3 model B), and you can increase the throughput to at least 300+ Mbps (up from the standard 100 Mbps connection via built-in Ethernet). Powered by USB port - no external power adapter required Supports suspend mode and remote wakeup via link-up and magic packet Supports both full-duplex and half-duplex operations Compliant with IEEE 802.3 (10Base-T) and 802.3u (100Base-TX) standards Allows your computer to instantly connect to a Gigabit network through a USB port - no need to open up your computer case to add an internal Ethernet card Linux Kernel 2.6.14 and later compatible Windows XP, Vista, 7, 8, and 8.1 compatible IBM compatible Pentium-233MHz or faster PC or Mac Compliant with USB 2.0 and USB 1.1 specifications Furthermore, the adapter is compact and is USB bus-powered requires no external power adapter. The adapter's compliance with USB 2.0 (480Mbps) ensures true Gigabit network speed without any compromise. Tripp Lite's U236-000-GBW, USB 2.0 Gigabit Ethernet Adapter, allows your computer to instantly connect to a Gigabit network through a USB port - no need to open up your computer case to add an internal Ethernet card.
