Intel Atom 330 AU80587RE0251M

Specifications

The first dual-core Atom microprocessor, model 330, was introduced five months after the launch of Atom family. The processor is based on 45nm Diamondville core, and includes two cores as two separate dies in one package. Each CPU core in Atom 330 is nearly identical to Atom 230: 32 KB + 24 KB L1 caches, 512 KB level 2 cache, 1.6 GHz core frequency, 533 MHz quad-pumped Front Side Bus, support for EM64T (64-bit) and HyperThreading technologies. In a sense, the Atom 330 is just like two Atom 230s in one package, even 330's Thermal Design Power is twice higher than TDP of a single 230 CPU. The 330 has better performance in multi-threaded applications, and provides better user interface responsiveness than single core Atom 230. The atom 330 CPU is packaged into the same 437-ball BGA package as Atom 230 and other netbook-oriented CPUs.
