I wonder if this has changed over the last few years since this got published early 2023: [Wayback/Archive] Memory Bandwidth Per Core and Per Socket for Intel Xeon and AMD EPYC
While we are looking at bandwidth per core, the performance per core has increased by 2.5-3x over the past decade.

For my link archive a router I bought a few years back: [Wayback/Archive] GL-SFT1200 Secure Wi-Fi Router On The Go – AC1200 Dual-Band Gigabit Wireless Internet Router | IPv6 | USB 2.0 | MU-MIMO | 128MB RAM | Repeater Bridge | Access Point-M Mode: Amazon.de: Computer & Accessories
I needed it because from prior experience, I knew GL.iNEt can support a special Wireless Repeater mode where it still functions as a router (hiding the LAN/WLAN behind NAT)
Two physical drawbacks likely due to the portable nature:
the plastic RJ45 ports are slightly too wide which means that these keep falling out [Wayback/Archive] Inline® Dust cover, for RJ45 socket, color: green, 100pcs. Pack: Amazon.de: Electronics & PhotoOne firmware drawback: it shipped with v3.212 for which I could not find release notes. Luckily the firmware v3.215 I upgraded to had: [Wayback/Archive] Firmware v3.215 is released – Technical Support – GL.iNet.
Links to product and manuals (the paper manual are just two thin sheets, but the on-line documentation is OK; I was surprised WireGuard and Tor were supported!):

An open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices
Via [Wayback/Archive] @jilles_com@infosec.exchange on Twitter: “Will be taking to meshtastic.org Lora 433MHz modules to @hotelhacker. Might be cool if more people could bring some to setup a larger mesh and play with them. amzn.eu/d/aCgULy4“
Products:
For both boards, this holds:
1. The Meshtastic program is not pre-installed on this product. If you need to install, please check the steps:
github.com/geeksville/Meshtastic-Android/blob/master/README.md
github.com/meshtastic/meshtastic-device/releases
2. If GPS does not work, the following situations may occur:
Install the Meshtastic firmware before and now reset the GPS when you switch to another firmware.
Reset steps: github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series/tree/master/firmware/GPS_%20reset_test
3. If GPS is weak indoors, it can be used outdoors
4. The GPS antenna is not installed stably, you can check if the interface is attached to the GPS antenna
