Rumors Suggest Intel’s Upcoming Tiger Lake-U Laptop CPU Features LPDDR5 Memory

According to a submission handed into the Eurasian Economic Commission on October 18th, Intel’s next-generation Tiger Lake-U CPU is expected to handle not only LPDDR4X but also LPDDR5 RAM memory.

Tiger Lake-U CPU Specs

Intel’s Tiger Lake-U processor is the second chip to benefit from 10nm tech (after the Ice Lake) and is slated to be a new architecture quad-core chip with a new Gen12 Xe Graphics engine, next I/O technology, and the latest display technology.

LPDDR4X already cranks speeds up to 4,266 Mbps, while LPDDR5 takes it higher to 6,400 Mbps. The latter also offers a boost in power efficiency. Samsung says to the tune of 45% when viewed next to LPDDR4X. The manufacturer already uses LPDDR5 chips in its phones, so it stands as a pretty reliable source.

Energy efficiency isn’t exactly what seeps to the surface first when memory springs to mind, but framed within Intel’s plans to succeed its existing Ice Lake CPUs with Tiger Lake-U specifically for smaller and thinner laptops, any savings can help extend battery life.

Alongside LPDDR5 support, previous rumors up the L3 cache size to 12 MB from Ice Lake’s 8 MB, which in practice means each core has 3 MB. A bump of 50%. It’s also expected to have eight threads to its four cores.

The same leak hints at Hyper-Threading and AVX-512 support, suggesting compatibility with a broad cross-section of computing tasks from analytics to simulations by way of AI, modeling, and processing.

Final Word

As for what else we know about the Tiger Lake-U, details are scarce, but the grapevine bandies PCI Express 4.0 support about has a possible feature, which could increase SSD transfer rates up to 5 GB per second.

In terms of clock speeds, we don’t have an official reading, but leaks point towards 1.0 GHz as a good bet for the base clock speed, and 3.4 GHz for Turbo Boost.
