It seems that both 5000+ and FX62 come as socket AM 2 only things. We suspect that we are talking about a speed update of both cores and we expect that the 5000+ could end up at 2.6GHz while the FX 62 will rock at 2.8 GHz.
Both CPUs will have dual core under the hood. We cannot confirm the frequencies at this time but there is a possibility that AMD won't change the clocks, and that it will count DDR 2 as the speed update. We are not sure yet, but this has happened before.
This will come as a disappointment to some, for according to the current plans the FX60 will remain the fastest FX for socket 939. Athlon 4800+ will be the fastest 939 dual core CPU around. You should be able to grab those AM2 CPUs just after Computex. µ
