Bay Trail D is Intel's big quad-core hope for the desktop market and it looks like that this System on Chip part might lose its well-known Atom branding. From what we saw Intel plans to use the Celeron brand for entry BGA based SoC parts.
The list of processors includes the Celeron J1750 that is set to replace the D2550 Atom BGA Cedar View Atom as well as Celeron J1850 that should replace Celeron Sandy Bridge based 847 and 807 processors. The Pentium branded J2850 should be faster than Celeron 1007U based on the Ivy Bridge architecture and both of these Bay Trail D based BGA parts are coming in Q4 2013. At this time we expect to see the mobile version of Bay Trail as well.
Intel has high hopes for this new generation of Atom processors, which evidently won't have an Atom name at least, not in the desktop version, but will come with new and improved quad core as well as new DirectX 11 compatible graphics.
