Notebook processors: Intel is phasing out “Lakefield” and 15-watt six-cores

Intel is phasing out ten Lakefield (Core iL) and Comet Lake-U (Core i-10000U) mobile processors. Manufacturers can still order the affected CPUs in the coming months; Intel will deliver the last copies in April 2022.

Under the code name Lakefield, Intel presented its first hybrid processors with different CPU cores. The Core i5-L16G7 and Core i3-L13G4 combine four Tremont cores of the Atom class with a fast Sunny Cove (otherwise used in Ice Lake CPUs), and they also rely on modern packaging technology for stacking several chips, called Foveros .

Only Lenovo’s folding tablet ThinkPad X1 Fold and Samsung’s light notebook Galaxy Book S with the higher clocked Core i5-L16G7 appeared in Germany. For Intel, Lakefield was primarily a test generation to try out the hybrid CPU concept with Windows and Foveros. The series was just a year old before Intel announced the transition to end-of-life (EOL) status (PDF download).

With the next CPU generation Alder Lake, Intel is rumored to cover the entire product range from tablet processors with 5 watts of low power consumption to high-end models with 55 watts. All should rely on a combination of Golden Cove and Gracemont cores with 10 nanometer technology. The 5-watt CPUs beat in the same notch as Lakefield with five processing cores.

Comet Lake-U, led by the Core i7-10810U, parallel to Intel’s first 10 nm series Ice Lake-U (Core i-1000G). Instead of 10 there were 14 nm structures, but with up to six instead of a maximum of four CPU cores. Since the introduction of Tiger Lake-U (Core i-1100G), however, the 15-watt six-core has only been a niche existence – in the they will disappear completely in the next six months (PDF download). Alder Lake also covers this performance class with 6 to 14 core cores in a hybrid mix.

[Update, 07.07.21, 12:30 Uhr:] The Ice Lake-U series, which became obsolete with the successor Tiger Lake-U, has discontinued Intel (PDF download).
