Forces alignment in the AMD K7 chipset market
Leaving aside new processor platforms, the good old AMD K7 Socket 462 is still in the ranks. And VIA Technologies and NVIDIA are still the major players in the market of AMD K7 chipsets, but VIA offers wider solution range. To consolidate in the high-end segment it released KT400A with 333MHz FSB and DDR400 support. Besides, in may the company is to announce KT600 supporting DDR400 and 400MHz FSB. Only time will tell if VIA is able to press NVIDIA with its nForce2.
