While I'm very happy with ipq806x for my needs (on a 100/40 MBit/s VDSL line), that platform is borderline at best (and probably just beyond the that imaginary limit) for 500/50 MBit/s (especially as a gaming router with SQM) - and those figures are already based on the faster ipq8065 chipset, with the ea8500 is using the slower ipq8064 SOC and the additional drawback that the ea8500 is only using a single CPU-port, while all other ipq806x devices use both.
