1.3GHz AMD Duron Arrives

A mere two weeks after releasing the Athlon XP 2000+ , AMD today announced the 1.3GHz AMD Duron processor for the "mainstream PC market." AMD says the new Duron processor is optimized for Windows XP Home and Professional OSs and supports DDR memory. It'll be priced at $118 in 1,000-unit quantities. The 1.3GHz Duron has 192 kB of total on-chip cache, a 200MHz front-side bus, a superscalar floating point unit with 3DNow! Professional technology, and hardware data pre-fetch. Durons are manufactured on AMD's 0.18 micron process. I know I haven't griped about this in a while, but if AMD switched to its new "MHz doesn't equal performance" naming scheme for its higher end Athlons (where one would assume that the users probably look at benchmarks) why is it sticking with GHz for "mainstream PC" chips (where you would imagine that users are less likely to look at benchmarks)?
