Two Cores, Too Cool

Intel doesn't take competition lightly, and low power consumption and high performance are at the top of its checklist. Its 64-bit Dual-Core Intel Xeon Processor 5100 family reduces power consumption by 40% compared to earlier dual-core Xeons, with a 135% performance increase. Targeting embedded applications like communication and storage, it's available for applications with extended lifecycles (five to seven years).

The processor chip uses the Intel Core microarchitecture, which supports Intel's latest virtualization technology. It has a 1333-MHz front-side bus (FSB) and a 4-Mbyte shared level 2 cache. The 2.33-GHz 5130 and 5140 chips consume 65 W, while the 2-GHz 5130 consumes only 40 W. All are based on 65-nm technology and work with the matching 5000P chip set. The 5000P can support a pair of dual-core processor chips

PCI Express constitutes the 5100P's memory hub controller's (MHC) links to the world. This includes the 6231ESB I/O controller hub for low-speed peripherals. Numerous storage and network PCI Express chips can be connected directly to the MHC or through a PCI Express switch.

The 5140 costs $445. The 5130 costs $316. A 3-GHz, 80-W 5160 is priced at $851.
