Another AMD First
AMD reached another important milestone in leading the industry toward pervasive 64-bit computing by being the first in the industry to demonstrate an x86 dual-core processor for 32- and 64-bit computing on August 31, 2004. AMD demonstrated a 4-socket server powered by four dual-core
AMD Opteron™ processors manufactured on the 90nm SOI process. AMDIt's evolutionary Direct Connect Architecture connects two cores on the same die. Since the AMD64 platform was first discussed publicly in 1999, AMD has indicated on multiple occasions that AMD64 was designed from the ground up to be optimized for multiple cores. AMD Opteron with dual-core processing is one more example of how AMD is extending its architectural leadership.
Learn more about AMD Opteron Dual-Core processors, the architecture, and watch a demonstration.
Dual-core AMD Opteron™ processors for servers and workstations will launch in mid-2005 followed by dual-core processors for the client market in late 2005 and will enable AMD to continue its x86 technology leadership. AMD is delivering technology leadership to benefit our server and workstation customers and giving our partners a competitive advantage in the market.
The AMD64 Dual-Core Advantage
Ease of Migration to Dual-Core Processors
- HP, IBM and Sun and other system manufacturers will be able to easily incorporate dual-core products into their existing AMD Opteron™ processor-based designs
- End users can upgrade their existing systems that are compatible with 90nm single core processors to dual-core processors
Higher Performance Per Watt
- Customers will experience the performance advantages of dual-core processors by getting the best performance per watt available in the market
Direct Connect Architecture
- Best 2-socket and 4-socket architecture for x86 computing
- Addresses and helps reduce the real challenges and bottlenecks of system architecture because everything is directly connected to the CPU
- Directly connects the two processor cores on to a single die to even further reduce latencies between processors
AMD Opteron Dual-Core Overview
- The AMD Opteron™ processor was designed from the start to add a second core
- Port already existed on crossbar/SRI
- One die with 2 CPU cores, each core has its own 1MB L2 cache
- Drops into existing AMD Opteron 940-pin sockets that are compatible with 90nm single core processors
- A BIOS update was all that was necessary to get the 4-socket server up and running with dual-core AMD Opteron processors
- The 2 CPU cores share the same memory and HyperTransport™ technology resources found in single core AMD Opteron processors
- Integrated memory controller and HyperTransport links route out the same as todayIt's implementation

鈥淒ual- and multi-core processor technologies on industry-standard servers will redefine scalability, performance and value for enterprise and SMB customers,"said Paul Miller, vice president of marketing, HP Industry Standard Servers. 鈥淗aving the industry's first dual-core x86 processors from AMD up and running on HP ProLiant servers demonstrates both HP's close relationship and collaboration with AMD and our ongoing commitment to rapidly deliver the best new technologies to our customers.”
“As AMDIt's strategic partner, we are in a unique position to support AMD64 dual-core technology with our hardware and software products,"said John Fowler, executive vice president of the Network Systems group at Sun Microsystems, Inc. “The Solaris OS combined with the AMD Opteron processor-based Sun servers and workstations will take full advantage of the AMD64 dual-core architecture, managing multi-thread applications with superior efficiency and performance.”
The e326's dual-core technology design puts IBM in the lead to help customers transition to future dual-core solutions. "Designing for the dual-core specification, IBM has invested to enable our customers to be more confident with their hardware investments," said Alex Yost, director of product marketing, IBM eServer. "For organizations with high-performance computing demands that want investment protection and a migration path from 32-to-64-bit applications, the eServer 326 provides an optimum platform for clustering at an affordable price."
Industry Support
鈥淒ual-core technology provides an attractive path for increasing processor performance with little or no increase in power consumption or heat dissipation,"observed Nathan Brookwood, principal analyst at Insight64. 鈥淎MD laid the groundwork for its dual-core processors years ago, when it gave its single-core AMD64 processors the on-chip plumbing they would need to support a second core at a later date. As AMD moves dual-core technology from theory to practice, it is reassuring to see that current investments in core logic and platform technology will remain relevant for years to come.鈥?br>
鈥淎MD has recognized the importance of keeping a compatible system architecture while still meeting todayIt's demanding computing needs,"said Kevin Krewell, editor-in-chief, Microprocessor Report, Instat-MDR. 鈥淎MDIt's demonstration of a current platform operating on dual-core AMD Opteron processors based on AMD64 technology represents another industry first for AMD as the company continues to provide industry-leading innovations to the industry-standard architecture.”
