RB850Gx2The RB850Gx2 is a five port Gigabit ethernet router. Comparing to the RB450G, the RB850Gx2 is much faster, with a dual core CPU, yet it still retains the same form factor, and will fit into the same enclosures.
The device is powered by a 533MHz P1023 PPC CPU, and also includes a temperature sensor and voltage monitor.

- All tests are done with Xena Networks specialized test equipment (XenaBay),and done according to RFC2544 (Xena2544)
- Max throughput is determined with 30+ second attempts with 0,1% packet loss tolerance in 64, 512, 1518 byte packet sizes
- Values in Italic indicate that max throughput was reached without maxing out CPU, but because board interface configuration was maxed out
- Test results show device maximum performance, and are reached using mentioned hardware and software configuration, different configurations most likely will result in lower results
