Today VIA announced the new DDR333 supporting chipset KT333. VIA again extends their leading position in AMD supporting DDR chipsets. The new revision step is not such an evolutionary leap as the introduction of the KT266A chipset was though. Nonetheless the new KT333 chipset will mark the performance bar among DDR333 solutions.

The VIA Apollo KT333 is the first VIA chipset to feature DDR333 memory offering 25% more memory bandwidth to the CPU. Supporting DDR200/266/333 memory and a complete range of 200/266MHz Front Side Bus AMD Athlon? XP and AMD Duron? processors, the VIA Apollo KT333 provides fast access to the faster system memory enabling best performance across the full application range. Included in the new chipset revision is the new VIA southbridge VT8233A supporting ATA133 naturally thus also harddisks bigger than 137GB. The Southbridge therefore performs 33% better in theory. Of course it still is downwards compatible to the older standards. Excerpt of the press release: Taipei, Taiwan, 20 February 2002 - VIA Technologies, Inc, a leading innovator and developer of core logic chipsets, microprocessors, and multimedia, networking and communications chips, today announced the launch of the VIA Apollo KT333, the first chipset to support new ultra fast DDR333 memory conforming to the JEDEC specification on the Socket A processor platform. With 25% more memory bandwidth, the VIA Apollo KT333 offers the ultimate in high performance computing, excelling in the most demanding applications, and fully exploiting the unmatched performance of powerful AMD Athlon? XP processors with QuantiSpeed? Architecture. Features & Benefits Summary Feature KT333 KT266A SiS 735 North Bridge VT8367 VT8366A SIS735 Processor Support AMD Athlon? XP AMD Athlon? XP AMD Athlon?
