Intel ‘Lakefield’ Hybrid Core/Atom CPUs Launched for Folding Display Laptops

Intel has introduced its first hybrid CPUs that mix its high-power and low-power architectures, often used within the separate Core and Atom product traces. The brand new ‘Lakefield’ CPU sequence fashions are focused at ultra-portable laptops and new type elements together with dual-screen and folding-screen fashions. Two CPUs have been introduced, the brand new Intel Core i5-L16G7 and Core i3-L13G4, every with one high-power core and 4 high-efficiency cores. They’ll first be seen in Lenovo’s ThinkPad X1 Fold and Samsung Galaxy E-book S. That is additionally the primary client utility of Intel’s Feveros 3D stacking CPU building expertise.

Intel stated in its announcement that the mixture of those new developments permits for a CPU that’s bodily 56 p.c smaller than present ones, resulting in smaller motherboards, higher flexibility in PC design, and after all smaller and lighter units. The chips devour as little as 2.5mW of energy in standby, which Intel says is a 91 p.c discount in comparison with an eighth Gen Core i7 Y-series cellular CPU.

The Core i5-L16G7 and Core i3-L13G4 each characteristic one Sunny Cove core and 4 Tremont cores. Intel first introduced Sunny Cove in late 2018, and it’s the similar structure that underpins present 10th Gen 10nm ‘Ice Lake’ CPUs for laptops. Tremont can also be a 10nm structure and succeeds Intel’s earlier low-power designs present in Atom, Celeron and Pentium Silver CPUs within the desktop, server, and embedded areas.

The brand new hybrid CPUs might be a part of Intel’s 10th Gen Core sequence alongside present elements based mostly on the Ice Lake and Comet Lake architectures. They might be differentiated by their numbering scheme, which reveals the relative energy of every CPU and its built-in graphics capabilities, mirroring the present Ice Lake laptop computer household. They are going to be formally described as “Intel Core processors with Intel Hybrid Know-how”.

Each new fashions have 7W TDP rankings and 4MB of cache reminiscence. The Core i5-L16G7 has a base velocity of 1.4GHz throughout all cores with single-core (the Sunny Cove core solely) and all-core enhance speeds of 3GHz and 1.8GHz respectively. It options 64 Gen11 graphics execution models. The Core i3-L13G4 runs at 800MHz with enhance speeds of two.8GHz and 1.3GHz respectively, and has 48 graphics execution models.

Intel guarantees an enormous leap in graphics efficiency for the 7W TDP CPU section. The Lakefield chips are additionally stated to be the primary with twin graphics pipelines, particularly optimised for multi-screen units. On-chip AI inference extensions are additionally supported, like with Ice Lake On the platform degree, there may be assist for Gigabit-class Wi-Fi 6 and LTE options and LPDDR4X-4267 RAM.

The Foveros 3D stacking method allowed Intel to develop this modular design, leveraging blocks of expertise with completely different architectures. Lakefield combines 10nm cores with bigger IO elements based mostly on older processes, very like AMD’s present chiplet technique with its Zen 2 structure. This might assist Intel cope with its ongoing 10nm manufacturing difficulties.

The Lakefield chips measure 12mm sq. and 1mm thick. The idea of mixing heterogenous high-power and low-energy CPU cores is frequent within the ARM-based cellular CPU house, with the association generally known as “huge.Little”. Intel says that the Home windows 10 scheduler is totally able to assigning duties to an acceptable core utilizing “hardware-guided” scheduling. 


Samsung’s Galaxy E-book S would be the first laptop computer that includes the Lakefield CPU when it goes on sale in some elements of the world later this month. Lenovo has additionally introduced its ThinkPad X1 Fold, which is anticipated to ship earlier than the top of 2020. Microsoft and Intel had beforehand introduced the dual-screen Floor Neo, which is now reportedly delayed or cancelled, and has not been talked about in right now’s announcement. Intel had additionally proven off an idea folding laptop computer based mostly on a Lakefield CPU at CES 2020.
