What the Atom E660T is

The Intel Atom E660T is the 1.3 GHz industrial member of the Tunnel Creek stack on BGA 676. It runs one Bonnell core with Hyper-Threading for two threads at 1.3 GHz with no turbo, backed by 512 KB of L2 cache. Power is rated at 3.6 W on a 45 nm process. Intel lists September 14, 2010 as the launch date with industrial temperature range.

At 1.3 GHz it leads Tunnel Creek control performance at the same 3.6 W as the 1 GHz part. The T suffix marks the industrial range version, while the E660 is commercial 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 E660T 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 3.6 W envelope suits passive spreaders.

Upgrade paths

There is no CPU upgrade path on BGA 676 because the chip is soldered. A 1.6 GHz E680T fits the same package where the vendor offers that board.

Frequently asked questions
