Intel's 11th generation Core Upgrade Exposition supports LPDDR5 memory

Mar 31,2021

Intel's 11-generation Core family is almost complete, including 10nm Tiger Lake-U Ultra-Low Power Mobile, 10nm Tiger Lake-H35 High-Performance Mobile, 14nm Rocket Lake Desktop, and only a 10nm Tiger Lake-H45 High-Performance Mobile.


According to the latest leaks, Intel is already preparing an update to the Tiger Lake-U series, even the just-released Tiger Lake-H35.

There are two versions of the Tiger Lake-U series. One is the i7-1195G7, and the other is the i5-1155G7. They are the popular versions of the current i7-1185G7 and i7-1145G7.


The specific specifications of the new model are not known. Still, it is not hard to guess that it must be mainly to increase the frequency, which may accelerate by 100-200MHz, perhaps because of the gradual maturity of the 10nm process.

There are also two upgraded versions of the Tiger Lake-H35 series; one belongs to I7, but the specific number is not precise. The other is I5-11320H, which should correspond to I7-11370H, I7-11375H, and I5-11300H, respectively, naturally also higher frequency.


Interestingly, in addition to being faster, the Tiger Lake-U series will finally open up LPDDR5 memory support.

In late August, before the release of the Tiger Lake-U series, Intel made it clear that it would support LPDDR5-5400 up to and including LPDDR4-4267(as well as DDR4-3200). The reason for this was never explained, but now it's finally coming.

LPDDR5 has been widely used in high-end smartphones. Compared with LPDDR4X, LPDDR5 has a higher frequency, more robust performance, and lower voltage and lower power consumption, thus significantly improving energy efficiency.


The Tiger Lake-H35 is architecturally identical to the Tiger Lake-U series, but it is unknown if the new version will also support LPDDR5.
