The Bearlake chipset will be introduced in second quarter of 2007, and Intel has reserved a grand total of four products for Q2'07 with two more products in Q3'07. Dragontail Peak (Bearlake-P NorthBridge with ICH9DH SouthBridge chips) and Frostburg (BearLake-G and ICH9) are utilising the ATX form factor, while Johannesburg/Montpelier (BearLake-Q and ICH9DO) and Buffalo Creek (BearLake-G and ICH9) come in the µATX form factor.
In Q3'07, Intel will introduce Bonetrail, successor to the high-end D975XBX (known as Bad Axe) motherboard. Based on the BearLake-X chipset, this baby brings support for 1.33GHz FSB and DDR3 memory at 1.06GHz. Form factor? ATX, of course.
A final BearLake motherboard is targeted for LXIV and desktop platforms: Apache Lake is based on a refreshed BearLake-G+ chipset with ICH9DH SouthBridge chip. This baby will bring support for DirectX 10 graphics in a form of unified shaders.
Performance is still set to be mediocre, but hey - until the co-processor model with Intel's discrete parts starts to kick in, you forget about performance. µ
