AMD has launched the latest versions of its single-core 64-bit Opteron processors, with both HP and Sun planning to ship new systems containing the chips.
AMD said both the 256 and 856 Opteron processors were immediately available to PC and server suppliers. The lower-end 156 model will be available next month, said AMD.
The chips run at up to 3GHz to enable users to run demanding applications more efficiently.
Sun will use the new AMD chips in both workstations and servers, while HP will use them in workstations. AMD said the launch of the new chips completed its single-core product roadmap.
Both AMD and Intel are currently battling it out to see which of them can take the lead with dual-core. Dual-core chips have two processors on a single piece of silicon to almost double processing speeds.
AMD said it would continue to manufacture single-core chips as long as there was the demand for them.
