What the Atom N475 is
The Intel Atom N475 is a single core Pineview netbook processor on BGA 559. It runs one Bonnell core with Hyper-Threading for two threads at 1834 MHz with no turbo, backed by 512 KB of L2 cache per core. Power is rated at 7 W on a 45 nm process with 123 million transistors. Intel lists June 1, 2010 as the launch date.
The N475 refreshes the N470 with DDR3 support added alongside DDR2 at about the same clocks. Against the N455 at 1667 MHz it adds speed for page loads. GMA3150 integrated graphics cover netbook displays, though without SSE4 support modern games struggle.
Memory is single-channel DDR2 or DDR3 fixed per design.
Socket and motherboard compatibility
The Atom N475 is soldered to the board in BGA 559 and cannot be replaced.
The NM10 Express chipset pairs over DMI, so firmware must list the SLBX5 sSpec. The CPU cooler compatibility by socket guide covers soldered rules.
Memory, PCIe and cooling
Memory is single-channel DDR2 or DDR3 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 7 W.
Upgrade paths
There is no CPU upgrade path on BGA 559 because the chip is soldered. An N550 adds a second core in the same package class where offered.
