For many months, Intel has been taking samples of motherboards based on 10-nm Lakefield processors to industry exhibitions, and has repeatedly talked about the progressive three-dimensional Foveros layout that they have used, but could not give a clear announcement and characteristics. It happened - Only two models are offered in the Lakefield family.
The creation of Lakefield processors gives Intel several reasons to be proud. In a case measuring 12 Γ 12 Γ 1 mm, several layers housed computational cores, system logic, power elements, integrated graphics, and even LPDDR4X-4267 memory with a total volume of 8 GB. A lot has been said about the layout of Lakefield computing cores: four economical cores with the Tremont architecture are adjacent to one productive core with the Sunny Cove architecture. Finally, Gen 11 integrated graphics have native support for dual displays, allowing Lakefield to be used to create mobile devices with a folding screen.
In idle mode, the Lakefield processor consumes no more than 2,5 mW, which is ten times less than the larger Amber Lake-Y mobile processors. Lakefield processors should be produced on 10nm technology of the same generation as Tiger Lake or Ice Lake-SP, although this concept is rather arbitrary. We should not forget that one of the "layers" of the silicon "sandwich", which is Lakefield, is manufactured using 22-nm technology. Computing cores and integrated graphics are located exactly on a 10-nm crystal, which determines the primacy of this technology when describing a processor.
The range of Lakefield models is limited to two items: Core i5-L16G7 and Core i3-L13G4. Both offer a combination of "4 + 1" computing cores without multithreading, are equipped with 4 MB of cache, have a TDP of no more than 7 W and graphics subsystem frequencies from 200 to 500 MHz inclusive. The difference lies in the frequencies of the computing cores and the number of graphics execution units. The Core i5-L16G7 has 64 graphics execution units, while the Core i3-L13G4 only has 48. The first of the processors operates at frequencies from 1,4 to 1,8 GHz with all cores active, the second - from 0,8 to 1,3 GHz with all cores active. In single-core mode, the former can reach a frequency of 3,0 GHz, the younger one can only reach 2,8 GHz. The memory mode, its type and volume, apparently, are the same for both processors: 8 GB LPDDR4X-4267. The older model boasts support for the DL Boost command set.
Lakefield-based systems can support gigabit Wi-Fi 6 and an LTE modem. In terms of interfaces, support for PCI Express 3.0 and USB 3.1 is implemented in the performance of Type-C ports. UFS and NVMe SSDs are supported.
The Microsoft Surface Neo is gone from the list of Intel Lakefield-based devices this year, but the Lenovo ThinkPad X1 Fold is still due before the end of the year, and the Samsung Galaxy Book S will hit select markets this month. In fact, this circumstance allowed Intel to organize a formal announcement of Lakefield processors right now.
