IBM is shipping its first copper-based microprocessors and also announced yesterday that it is embarking on various projects related to copper.
IBM has released a PowerPC 740/750 with a 400MHz copper chip, the company said in a statement, and plans to use copper microprocessors in its S/390, RS/6000 and AS/400 server lines. Prototypes should be out later this year and production systems are expected next year. Pricing and availability details on the PowerPC were not provided.
The company's standard foundry services will also create copper chips for other companies, according to the statement.
IBM said that its use of copper in chips enhances microprocessor performance and decreases die size and power consumption, and that it is the first chip maker to roll out copper-based microprocessors and embedded processors for electronic products.
