ECS has announced a family of Mini-ITX motherboards with soldered-on Bay Trail processors. The BAT-I lineup employs Bay Trail-D, the desktop variant of Intel's latest SoC, and there are three processor options. The top of the line sports the Pentium J2850, which has quad cores clocked at 2.4GHz. In the middle of the pack, the Celeron J1850 serves up four cores at 2GHz. Then there's the Celeron J1750, a duallie clocked at 2.4GHz.
All three of the Bay Trail-D variants sport HD graphics derived from Intel's Ivy Bridge IGP. That integrated GPU has the same 688-792MHz frequency range regardless of the model.
These desktop-bound Bay Trail chips have 10W TDP ratings, so they don't require aggressive cooling. The ECS boards get by with relatively small passive heatsinks. They're little short on connectivity, though. ECS mentions one Mini PCIe x1 slot, one USB 3.0 port, and dual 3Gbps SATA ports. Video outputs include HDMI and VGA, but we don't have a full spec sheet. There's no word on pricing or availability, either.
Given the performance of the Atom Z3740 in Asus' Transformer Book T100 convertible, the quad-core Pentium and Celeron chips should be reasonably capable. Scaling back to two cores on the Celeron J1750 might be cutting it a little too close, though. Thanks to AnandTech for the tip.
