Intel’s 14nm Broadwell is the True 14nm Node – Professional Analysis Confirms

The first sampling of Intel Broadwell processors arrived a few days ago
in the form of Core M SoC in Lenovo’s Yoga 3 Pro Ultrabook. Though
initial reviews of the same are somewhat disappointing, since our sample
size is very limited, it would be a fallacy to pin the blame on Intel’s
part. Atleast,  not until more samples arrive (and provided they
perform just as ‘average’). In the meantime however, the well known
reverse engineering publication Chip Works has released its analysis of Broadwell.

Anyways, the folks over at Chipworks
applied bevel polish to a bare die and analyzed the chip. The first
thing they measured was the Transistor Gate Pitch which is more or less
the distance between two gates. Since at this level of magnification you
work on reference points, the approximate distance between a handful of
gates is noted and divided to get the physical pitch (699/10). As you
can see, the number ’70nm’ corresponds to the forecast by Intel in their
original slides.  The only anomaly they noted is the interconnect
pitch, which measures 54mm on the reverse scale. This measurement is
quoted by Intel as being 52mm. Chipworks notes that this could be due to
a sampling error or a measurement error as well. Now, some of the stuff
they mention is frankly above my pay grade so you would do well to read
the full analysis on their page. Note however, that the full technical
analysis has yet to be revealed and you will need to cough up cash for
that.
