Two Taiwanese companies have announced plans for future chipsets, which connect the microprocessor to the rest of the computer. SIS said it will release a chipset containing integrated graphics for AMD's Athlon and Duron processors in September for $42. Meanwhile, Via Technologies announced an architecture for chipsets that can use Double Data Rate (DDR) DRAM, a faster version of today's computer memory. Samples of these DDR chipsets, which will work with Intel and AMD processors, will come out in the first half of 2001.
