Out of all the semiconductor industries in existence, there aren’t many with as much competition as the CPU chipset market can claim. There are a grand total of 7 companies producing chipsets for Pentium 4, Athlon XP, or future generation platforms (Intel, AMD, VIA, SiS, NVIDIA, ATI, and ALI). Intel is the largest chipset designer of them all, but two other companies are battling it out for the runner-up position, namely VIA and SiS.
