Good Old Newbie: Intel's Celeron 1.7 GHz for Socket 478

The Main Competitor: AMD Duron

AMD has given Intel quite a hard time - all versions of the Duron have clearly been faster than the Celeron at the same clock speed. Until today, the has had the big advantage in that it can make use of the same platform, the same chipsets and the same type of memory that is used by the Athlon and the Athlon XP. Naturally, a Duron paired with DDR memory would always be faster than a Celeron with conventional SDRAM. Now, the Duron no longer has this advantage, because the Celeron 1.7 GHz gives you the option of using various chipsets, DDR-SDRAM and even RDRAM.
