DDR4 WHITE PAPER
Conclusion
Much like each memory technology transition that preceded it, DDR4’s value upon
introduction may seem nebulous compared to the incumbent DDR3. DDR2 operating at
the same frequency as mainstream DDR was slightly slower, DDR3 had the same issue with
DDR2, and DDR4 will have the same issue with DDR3. This is expected; each transition
meant slightly looser timings. Yet each time, the newer specification was implemented less
to improve the present and more to meet the needs of the future. DDR4 is no exception.

Where DDR4 does deviate substantially from its predecessors is in how dramatic the
changes in specification and architecture are. Each iteration of DDR memory brought
with it the same three improvements: increased speed, increased density, and reduced
power. The differences in scale, however, are massive, and DDR4 in particular is the most
spectacular leap yet.

Figure 6: DDR specification comparison.
Improvements in speed and voltage have been fairly steady, but potential capacity sees
an absolutely staggering increase from DDR3. Even ignoring the potential of 3DS, DDR4
DIMMs are expected to hit 16GB in 2015 and specified to go up to 32GB. None of this
accounts for the improvements in reliability and stability baked into the DDR4 specification.

DDR4 is the most forward-thinking mainstream memory technology yet. Today it brings
all of these improvements to Intel’s 2014 Haswell-E architecture for enterprise and high
end desktop processors. The future will see increases in density, reductions in operating
voltage, and higher speeds, giving this new technology the potential to continue to meet
the demands of its host system for years to come.
