Four SKUs appear to be on the way: the Z3740, Z3770, Z3740D and Z3770D. The D suffix denotes chips with single memory channel support and a somewhat weaker GPU. All the chips have four CPU cores and 2MB of L2 cache. However, D-series chips should end up slower, clocked at 1.8GHz, while the Z3740, and Z3770 will run at up to 2.4GHz.
The D-series features support for 2GB of DDR-1066 memory, while non-D parts can handle up to 4GB of DDR3L 1333. As a result, non-D parts deliver a lot more memory bandwidth, 17.1GB/s vs. 10.6GB/s on D-series SKUs.
It is still unclear what sort of Intel HD Graphics we can expect, but the slides show that D-series chips support displays up to1080p, while the other two can handle 2560x1600 displays.
The Z3740 and Z3770 have an SDP of 2W, while the Z3740D and Z3770D end up in the 2.2W to 2.4W range. No word on actual TDPs though.
