AMD Introduces Five New Energy-Efficient Quad-core Opterons
AMD has announced five new quad-core Opterons with a TDP of 68W. With its energy-efficient models, the manufacturer mainly focuses on data centers. AMD was previously only able to supply 95W quadcore Opterons.
With energy costs and equipment cooling becoming increasingly important factors in data centers, and given the fact that Intel introduced Xeon server chips with a 50W TDP at the end of March, AMD was forced to come up with energy-efficient Opterons.
It goes according to the announcement from AMD to offer three models with clock speeds from 1.7GHz to 1.9GHz for dual-processor configurations. In addition, the company is introducing two variants, a 1.8GHz and a 1.9GHz model, for systems with eight CPUs. Compared to the other quad-core Opterons for multiprocessor systems, the energy-efficient models work with a slightly lower voltage of 1.15V compared to 1.2V. The tdp of the other Opterons starts at 95W and goes up to 119W for the fastest versions. The energy-efficient Xeons also have a higher maximum clock speed of 2.6GHz.
Only with the arrival of the 45nm-Shanghai server chip, the successor to the Barcelona, at the end of this year can the tdp of AMD’s quadcores decrease drastically.
