AMD will extend its Socket AM2 Athlon 64 X2 line-up in Q3 with the debut of the 5200+, allegedly leaked roadmaps now turning up on a variety of websites reveal. The 65W TDP part will be joined by the 125W TDP Athlon 64 FX-64 the following quarter.

Both parts are to be fabbed at 90nm. The anticipated 65nm version of the 5200+ now looks unlikely to appear before Q2 2007, but which time AMD will have shipped the 90nm 5400+ and possibly the 5600+, both running at 89W.

As per past roadmaps, the first 65nm chips - codenamed 'Brisbane' - will debut in Q1 2007, though shipments will commence in December this year, the documentation maintains - as per past roadmaps. The 3800+, 4200+ and 4600+ will ship in that timeframe, joined by the 5000+ and 5200+ in Q2. Missing are the 4400+ and 4800+ seen on past roadmaps, but that's consistent with AMD's recent policy of knocking 1MB L2 parts on the head in favour of 512KB version.

All the 65nm parts are down as having a TDP of 65W - the same as their 90nm equivalents.

The FX-64 will co-exist with the FX-62 for a quarter before replacing the older chip entirely in Q1 2007. Come Q3, and it will be joined by the FX-66. ®
