Oh this is great. WiFi and gbit ethernet onboard is what I needed. Is USB and network bandwidth still shared?

- mixmastamyk 7y agoPossibly, but usb3 is a lot faster.
- slartibardfast0 7y ago"The Ethernet controller on the main SoC is connected to an external Broadcom PHY over a dedicated RGMII link, providing full throughput. USB is provided via an external VLI controller, connected over a single PCI Express Gen 2 lane, and providing a total of 4Gbps of bandwidth, shared between the four ports." Better than one could've hoped!!
- llao 7y agoOh wow, this will make one of my projects go from four raspberrys to one.
- sofaofthedamned 7y agoNope, it's completely unfettered by USB this time.
- Arbalest 7y agoNope, according to https://opensource.com/article/19/6/raspberry-pi-4 https://opensource.com/article/19/6/raspberry-pi-4 > The BCM2835-based chip in Raspberry Pi 1 to 3 provided just one native USB port and no Ethernet, so a USB hub on the board provided more USB ports and an Ethernet port. The 3B+ added a dedicated LAN chip, which gave it Gigabit Ethernet, but this was limited to USB2 speeds. The Pi 4 has dedicated Gigabit Ethernet, and because it's no longer throttled over USB, its networking speeds are much faster.
