Diamondville is the core name for Intel's first generation of Atom processors based on the Bonnell microarchitecture. Those ultra-low power chips were manufactured on Intel's 45 nm process and were specifically aimed for nettops, netbooks, and entry/value desktops. Diamondville effectively replaced Stealey in the netbooks and entry-level desktops segment.

Diamondville-SC refers to all the single-core Diamondville-based microprocessors. In late 2008 Intel introduced a single dual-core variant (the Atom 330) which went under the Diamondville-DC codename. The dual-core version is simple two identical Diamondville-SC dies packaged together.

Overview

All models are based on Bonnell manufactured on a 45 nm process and implement x86-32. Both Diamondville and Silverthorne use the same die. A number of Diamondville models do have additional features not enabled on Silverthorne models such as full support for x86-64. Diamondville generally targets the 4-8 W thermal envelope typically fan-less designs.
