New Atom models target low-cost PCs
Jun 3, 2008 — by LinuxDevices Staff — from the LinuxDevices Archive — 10 viewsIntel has announced a second wave of Atom processors, targeting simple desktops and notebooks the chipmaker dubs “nettops” and “netbooks.” The Atom N270 and 230 processors are accompanied to market by matching 945GSE and 945GC chipsets and low cost SSDs (solid state drives).
Formerly code-named “Diamondville,” the N270 and 230 are identical architecturally to the Z-series Atom processors (“Silverthorne”), which targeted MIDs (mobile internet devices) and were announced in April. The only technical differences in the new Atoms are their size and power consumption.
Acer, the world's third-largest PC maker, is already showing off a Linux-compatible N270 Atom-based netbook called the Aspire One, due in the third quarter.
Where the Z-series Atoms come in a 13mm x 13mm package, the N270 and 230 — also produced using Intel's 45nm High-k manufacturing process — measure 22mm x 22mm. Both the N270 and 230 clock at 1.6GHZ, making them comparable in processing power to the earlier Z530. The new parts also share the Z530's 512K of second-level cache and 533MHz frontside bus. But, where the Z530 has a TDP of 2 Watts, the N270 has a 2.5 Watt TDP, and the 230 an even-more-hungry 4 Watts.
Why would anyone buy a larger processor that also consumes more power? One answer is pricing: The Z530 goes for $95, including its SCH companion chip, while the N270 and 230 cost $44 and $29, respectively. While the latter prices don't include chipsets (see below), the Diamondville parts are clearly more affordable.
In addition, the new Atoms are the clear choice for anyone who wants to run Windows Vista. The 945GSE and 945GC chipsets, also announced today, use Intel's Graphics Media Accelerator 950 core, making them compatible with Windows Vista Premium, including its “Aero Glass” interface.
