What the Atom E680 is
The Intel Atom E680 is the fastest commercial Tunnel Creek part on BGA 676. It runs one Bonnell core with Hyper-Threading for two threads at 1.6 GHz with no turbo, backed by 512 KB of L2 cache. Power is rated at 4.5 W on a 45 nm process. Intel lists September 14, 2010 as the launch date with commercial temperature range.
At 1.6 GHz it leads the E600 stack in single threaded control tasks. The E680 is commercial, while the E680T is industrial at identical clocks and power. GMA600 graphics at 400 MHz cover kiosk displays.
Memory is single-channel DDR2 up to DDR2-800 with up to 2 GB fixed per board.
Socket and motherboard compatibility
The Atom E680 is soldered to the board in BGA 676 and cannot be replaced.
Compatibility depends on firmware with the B0 stepping. The CPU cooler compatibility by socket guide covers soldered rules.
Memory, PCIe and cooling
Memory is single-channel DDR2 up to DDR2-800 with up to 2 GB, fixed per board.
Expansion comes from 4 PCIe x1 lanes plus display, audio and SPI.
Cooling has no retail answer. The 4.5 W envelope suits small passive spreaders.
Upgrade paths
There is no CPU upgrade path on BGA 676 because the chip is soldered. Keep the E680 where the fastest Tunnel Creek core covers the workload.
