Intel's Xeon D SoC lineup will soon expand to include 12-core and 16-core options, after the platform launched earlier this year with the option of 4 or 8 cores for the 14 nm chips.
The report yesterday from CPU World offers new details on the refreshed lineup which includes both Xeon D and Pentium D SoCs:
"According to our sources, Intel have made some changes to the lineup, which is now comprised of 13 Xeon D and Pentium D SKUs. Even more interesting is that Intel managed to double the maximum number of cores, and consequentially combined cache size, of Xeon D design, and the nearing Xeon D launch may include a few 12-core and 16-core models with 18 MB and 24 MB cache."
The move is not unexpected as Intel initially hinted at an expanded offering by the end of the year (emphasis added):
"…the Intel Xeon processor D-1500 product family is the first offering of a line of processors that will address a broad range of low-power, high-density infrastructure needs. Currently available with 4 or 8 cores and 128 GB of addressable memory…"
Current Xeon D Processors
The new flagship Xeon D model will be the D-1577, a 16-core processor with between 18 and 24 MB of L3 cache (exact specifications are not yet known). These SoCs feature integrated platform controller hub (PCH), I/O, and dual 10 Gigabit Ethernet, and the initial offerings had up to a 45W TDP. It would seem likely that a model with double the core count would either necessitate a higher TDP or simply target a lower clock speed. We should know more before too long.
