Sun Microsystems CP3220 manual AMD Opteron Processor

5.2The AMD Opteron Processor

AMD Opteron processors with Direct Connect Architecture include several new features, including seamless quad-core upgradability and DDR2 memory. AMD Opteron processors with DDR2 memory feature a common core architecture that is consistent across 1-way, 2-way, and 8-way systems. Features of the second generation 2.2-GHz AMD Opteron include:

■x64 Architecture (64-bit extensions) with AMD Direct Connect Architecture using HyperTransport technology supports simultaneous 32-bit and 64-bit computing

■Three HyperTransport links supporting up to 24 Gbyte/sec peak bandwidth per processor

■Integrated 128-bit wide DDR memory controller that reduces latency and increases performance

■Individual 1-MB L2 cache per core

■Low power usage and cooling requirements - AMD Opteron processors running at 68W offer efficient heat dissipation without reducing performance

■AMD PowerNow! technology can deliver performance on demand while minimizing power consumption

■DDR2-based systems can upgrade to Quad-Core AMD Opteron processors when they are available, within existing power and thermal envelopes

■NEBS certified

■Socket F 1207-pin

The following processors are supported on the Sun Netra CP3220 blade server:

■CPU, Opteron, Dual-Core, 2.2GH 68 W, NFP

■CPU, Opteron, Quad-Core, 1.8 GHZ 79W, NFP
