According to HKEPC, it’s now confirmed that the first desktop versions of the Shelton'08 platform which use an Atom "Diamondville" CPU will be launched starting in the second quarter. Some even mentioned the month of May.
Without surprise, the TDP will be higher than "mobile" Atoms; however, it’s still low compared to the 65W of most Core 2s. Note the arrival of a dual core version in the third quarter.
In terms of evolution, we shouldn’t be too demanding. The CPU in BGA format is soldered to the motherboard, there is no internal PCI-Express port, and we can only insert a single DDR2 module. We don’t know yet if this will necessarily be the case for all Shelton'08 motherboards or if only concerns the above Gigabyte model.
Nevertheless, one thing is sure, Intel still has some room to reduce the size of its upcoming Shelton platforms because currently it uses an IGP combined with a Southbridge. It’s entirely possible to regroup the two in a single chip.
