65nm Athlon 64 X2s to have 512KB caches after all?
Last week, Dutch site Tweakers.net posted a roadmap of AMD's upcoming 65nm Athlon 64 X2 processors that listed 4000+, 4400+, and 4800+ models with the same clock speeds and 1MB-per-core cache sizes as previous 90nm models. Moles over at motherboard manufacturers seem to have different information, however. According to sources quoted by HKEPC, those 65nm Athlon 64 X2 processors will indeed have 4000+, 4400+, and 4800+ model numbers, but they will be clocked at respective speeds of 2.1GHz, 2.3GHz, and 2.5GHz, all with 512KB of cache per core. AMD will reportedly be adjusting multipliers in 0.5x increments with the 65nm "Brisbane" core, enabling 100MHz higher clock speeds than current models.
Aside from the 65nm speed details, HKEPC's sources claim AMD will make some adjustments to its branding scheme come the rumored November launch of 4x4-bound Athlon 64 FX dual-processor kits. The "Athlon 64 FX" trademark will supposedly become exclusive to 4x4 dual-CPU systems, and Athlon 64 FX processors intended for single-socket systems will be renamed to bear the same Athlon 64 X2 moniker as the rest of AMD's dual-core lineup. Under the new naming scheme, the moles say AMD's upcoming 3.0GHz Athlon 64 FX-64 will be introduced as the Athlon 64 X2 6000+.
