"Advanced Micro Devices today announced its latest Opteron
processor, the 4100 family, aimed at the mid-market concerned with
power efficiency and performance per watt. It fills out the Opteron
server line just below the eight- and 16-core "Magny-Cours" line
for high-end users.
"Developed under the codename "Lisbon," the Opteron 4100 line is
the definition of an entry level part, as the cheapest model will
sell for just $99 for quantities of a thousand or more. Lisbon is a
four- or six-core processor with clock speeds ranging from 1.7GHz
to 2.8GHz, and power envelops as low as 32 watts and as high as 75
watts. Wattage and clock speed are, not surprisingly, tied together
-- the faster the clock, the higher the power."
