What the Atom Z670 is
Intel Atom Z670 is a single core Lincroft tablet processor that Intel released in April 2011 for Oak Trail tablets with soldered boards. It uses the Bonnell core design on a 45 nm process, running at 1.5 GHz with no turbo. The cache is 512 KB of L2, and Hyper-Threading turns the single core into 2 threads per ARK, against 1 thread in some database listings. Power is 3 W. Graphics come from Intel GMA 600 at a fixed 400 MHz.
The 300 MHz step over the Z650 at the same power marks the top of the Oak Trail tablet range. One threaded core with tablet graphics covers browsing and video in early tablets. The single channel DDR2-800 controller takes up to 2 GB beside the processor.
At 3 W the Z670 belongs to the fanless tablet group in sealed bodies. Fixed clocks keep behavior predictable. The LGA, PGA and BGA: CPU package types explained guide explains why this soldered BGA part cannot be serviced.
Socket and motherboard compatibility
The Atom Z670 solders to BGA 518 with 518 balls in a 13.8 × 13.8 mm footprint and cannot be moved to another board. Tablet makers qualify each model with a fixed board, BIOS and companion power chip, so another Atom part is not a field swap.
The BIOS must list the exact Atom Z670 string. The CPU cooler compatibility by socket guide notes soldered parts have no desktop mount.
Memory, PCIe and cooling
Memory support is DDR2-800 in a single 32-bit channel for up to 2 GB, usually soldered. The narrow bus fits tablet power budgets.
No PCIe comes from the CPU per ARK. Board I/O hangs off the SM35 companion chip, covering USB, SATA, display and audio.
Cooling uses a spreader for fanless 3 W operation. Fixed clocks need little airflow.
Upgrade paths
There is no CPU upgrade path on soldered BGA 518. The Atom Z670 cannot be removed, so a faster tablet means a new device. A slower single core comparison on the same package is Intel Atom Z650.
A platform move means a new tablet on a current mobile package. Recycle the old device after wiping data.
Frequently asked questions
What socket does the Intel Atom Z670 use?
It uses BGA 518, called T-PBGA518 in ARK.
How is the Atom Z670 different from the Z650?
Base is 1.5 GHz instead of 1.2 GHz. Cache, power and graphics match.
What memory does the Atom Z670 use?
DDR2-800 in a single 32-bit channel, up to 2 GB.
Can the Atom Z670 be upgraded?
No. The chip is soldered in a sealed tablet body.
