The 128MB DDR will be capable of supporting new RouterOS features.  The microSD slot supports an additional memory card that can be used for a Dude database and other features. The 680MHz Atheros MIPs 24K CPU with a 64KB/32KB instruction/data cache is probably the fastest CPU used in low cost wireless access points. The three Ethernets and mpci slots give you ample data interfaces to put the big CPU power to work.

Performance test results

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