In questi giorni si stanno concretizzando i rumors che davano i nuovi processori AMD Athlon XP in grado di supportare ufficialmente un bus di 333MHz. A partire dalla versione 2700+ infatti, sembra quasi scontato l'utilizzo di questa frequenza. Il supporto dal lato chipset non manca: la maggior parte delle schede madri con VIA KT333 potrà far funzionare questo processore tranquillamente, come tutte quelle che riescono a raggiungere questa frequenza stabilmente (ma sempre in overclock): vedremo quale sarà la casa produttrice che avrà un occhio di riguardo per i propri clienti introducendo divisori PCI adeguati. Il supporto ufficiale invece, sarà destinato solamente per ora a chipset come VIA KT400, SiS746 e 746DX, come si può leggere qui:

Advanced Micro Devices (AMD) has reportedly decided to change the FSB (front-side bus) standard of its upcoming Athlon XP 2700+ processor from the current 266MHz to 333MHz, contrary to its previous announcement that it would not alter the architecture of its K7-core Athlon XP products.

Although the update was unexpected, chipset design houses VIA Technologies and Silicon Integrated Systems (SiS) both said that it would not affect their product roadmaps, as they had already made their new AMD-based chipsets compliant with FSB 333MHz speeds.

According to VIA, its latest KT400 discrete chipset is able to support an FSB speed of up to 333MHz, so it will not encounter any compatibility problems with AMDÂ’s future Athlon XP processors. SiS noted that its new SiS746 and SiS746DX are also designed to be able to support FSB 333MHz speeds. The company added that shipments of the SiS746 chipsets would start shortly
