What the Atom N450 is
The Intel Atom N450 is a single core Pineview netbook processor from December 2009. It runs one Bonnell core with Hyper-Threading for two threads at 1.667 GHz with no turbo, backed by 512 KB of L2 cache. Power is rated at 5.5 W on a 45 nm process with the SLBMG sSpec. The task list shows 6 W while family tables show 5.5 W, which is noted below.
The N450 launched the Pine Trail platform with graphics and memory on die, cutting total kit power against the N280 generation. Against the N455 it matches clocks without DDR3 support. GMA3150 graphics at 200 MHz cover netbook displays.
Memory is single-channel DDR2-667 fixed per design up to 2 GB.
Socket and motherboard compatibility
The Atom N450 is soldered to the board in BGA 559 and cannot be replaced. Netbook repair means board replacement.
The NM10 Express chipset pairs over DMI, so firmware must list the SLBMG sSpec. The CPU cooler compatibility by socket guide covers soldered rules.
Memory, PCIe and cooling
Memory is single-channel DDR2-667 up to 2 GB, fixed per design.
PCIe comes from the NM10 chipset. Board wiring decides options.
Cooling is a small fan or spreader drawn for 5.5 W.
Upgrade paths
There is no CPU upgrade path on BGA 559 because the chip is soldered. An N455 adds DDR3 support in the same package class where offered.
