AMD Announces Quad-Core Opteron Server Chips

Advanced Micro Devices today showed a laboratory version of its promised "Barcelona" quad-core Opteron 8000 server chip to analysts gathered in Berkeley, California, and said it plans to begin selling the product in the second quarter of 2007.

AMD will pitch the chip to users of high-end, commercial workstations and servers. Users could see performance improvements of up to 70 percent in database applications and 40 percent in floating-point applications compared with AMD's dual-core "Rev. F" Opteron.

The demonstration was AMD's second effort to show that it is keeping up with quad-core chips from rival Intel. AMD also launched its "4x4" Quad FX Platform, a motherboard with two dual-core Athlon 64 FX-70 series chips intended for the desktop gaming market.

Chip Wars

Intel lost significant market share to AMD in 2006 as it endured criticism for being slow to produce chips that emphasized power efficiency instead of pure calculating speed. Intel has bounced back in recent months with the launch of dual-core chips including the Core 2 Duo for desktops and the Xeon 5100 "Woodcrest" chip for servers. On November 14, Intel reached the market first with quad-core chips, offering the Core 2 Extreme QX6700 for gamers and the Xeon 5300 for servers.

Intel has also led the industry in converting its chip designs from the 90-nanometer process to 65 nm, including all four processors mentioned above. In response, AMD has criticized Intel's quad-core design as merely gluing two dual-core Woodcrest chips together, whereas the Barcelona chip includes all four cores on a single piece of silicon. Analysts are divided on the impact of that distinction, and say they cannot measure the difference until they compare benchmarks from both finished versions.

Barcelona Impact

Still, AMD trumpeted Barcelona today as an engineering achievement that marks the company's shift to 65-nm architecture. By shrinking the processor die, AMD is able to improve power efficiency and squeeze an extra level of shared cache memory onto the design, said John Fruehe, AMD's worldwide market development manager for server and workstation products.

"As you add more cores, it becomes less about brute force and more about the efficiency of how many things you can do at once, and how efficiently you can order them," he said.

"From a customer perspective, those who will see the biggest bang for their buck with quad-core are people running applications like larger databases. The more threaded an application is, the more benefit you get."

The users who will see the greatest return on their quad-core investment are users of multithreaded applications like CRM (customer relationship management), ERP (enterprise resource planning), e-commerce, and virtualization, Fruehe said.

AMD will first launch the Barcelona design on a four-socket board (running four quad-core chips) and a two-socket board (running two quad-core chips). The company will wait until later in 2007 to launch single-socket Barcelona boards, which will be used mainly to develop new applications for the larger servers or to run Web farms to handle multiple simultaneous processing requests.

AMD expects server vendors such as Dell, Hewlett-Packard, IBM, and Sun Microsystems to adopt the new technology for their servers in 2007, although none of those companies has yet made a public announcement.
