AMD Phenom X2, X4, FX processor specs leak
'Star' chip roll out runs through to Q1 2008
Details are beginning to come through about just how AMD will roll out its next-gen desktop 'star' processors - so called because of their astronomy inspired codenames. While Q3 appears to be the key launch point, the shift extends through Q4 into Q1 2008.
According to roadmap details posted  by website DailyTech, Q3 will see the release of three Phenom FX processors , quad-core 65nm parts with four blocks of 512KB L2 cache and 2MB of shared L3 cache.
The roadmap lists two clock frequency ranges: 2.2-2.4GHz and 2.4-2.6GHz. The top band is taken by a Socket 1207+ part sitting on a HyperTransport 3 bus clocked at 3600MHz. The lower speed range extends two processors, both with 3200MHz HT3 buses, but one that connects using Socket 1207+ and the other with AM2+.
The same quarter will see the debut of two Phenom X4s, the report says - both quad-core desktop CPUs with Socket AM2+ interconnects, four 512KB L2 caches, one 2MB L3 cache and a power rating of 89W. A 2.2GHz part with operate on a 3200MHz HT3 bus, while the 2.4GHz version will sit on a 3600MHz bus.
Come Q4, and the 'Kuma' dual-core desktops will appear, as the Phenom X2 series. Expect three models: 65W parts running at 2.4GHz and 2.6GHz, and an 89W chip clocked to 2.8GHz. All three have two 512KB L2 caches and a 2MB L3 cache. They sit on 3600, 3800 and 4200MHz HT3 buses, respectively.
'Star' Athlons and Semprons won't appear, apparently, until Q1 2008: the 'Rana' dual-core 65W chip, clocked to 2.2GHz and with two 512KB L2 caches but no L3. The next-gen Athlon 64 X2's HT3 bus will be clocked to 3200MHz.
Expect two single-core Semprons, each with 512KB of L2, no L3, a 45W TDP, and clock speeds of 2.2GHz and 2.4GHz. Their HT3 buses will be set to 3200 and 3600MHz, respectively.
The Athlons and Semprons will be accompanied by three "energy efficient" Phenom X2s, clocked at 1.9, 2.1 and 2.3GHz for a TDP of 45W. Their HT3 buses will be set to 2800, 3000 and 3400MHz, respectively.
