Amd Moves To 45-nm Process Node With Shanghai

摘要

Advanced Micro Devices (AMD) moves to the 45-nanometer (nm) technology node with the launch of its new Opteron server chip, code-named Shanghai. AMD is the third manufacturer to reach this milestone after Panasonic and then Intel. AMD's previous generation 65-nm Barcelona was the industry's first quad-core processor that also included 2 Mbytes of shared L3 cache integrated on the same chip with a Northbridge memory controller. The Shanghai chip triples the L3 cache size to 6 Mbytes, but all the basic building blocks were already incorporated in the 65-nm Barcelona chip. A quick glance at the Shanghai chip confirms one of its major selling points. It is pin-for-pin compatible with the Barcelona processor. This approach continues a long-standing AMD strategy to allow server manufacturers to maximize the life of their designs for many generations without new sockets and board redesigns.
