Whats the difference between nighthawk xr500 and nighthawk x10
Both support 1,733 Mbps on ac at 5 GHz, and 800 Mbps on n/ac at 2.4 GHz. One big difference is that the X10 (R8900, R9000) supports link rates of 4,620 Mbps on 802.11ad at 60 GHz with a QCA9500 module, while the XR500 doesn't have an 802.11ad module.
Other than that, both use QCA9984 modules with 4-stream MIMO. Both have 1.7 GHz CPUs, but the X10 has double the flash storge and RAM (at 512 MB and 1 GB respectively). The X10 also has an SFP fiber port and different Ethernet PHYceiver chips, with 2 extra LAN ports. But if you just want 802.11ac Wave 2, MU-MIMO, and DFS coverage, you can get the XR500 since 512 MB of RAM is plenty meaty for your average household...
