Intel today unveiled a killer new product with which it hopes to bring about as big a change to mobile computing as Ultrabook did some eight years ago. This effort is a combination of a new mobile computing form-factor codenamed "Project Athena," and an SoC at its heart, codenamed "Lakefield." Put simply, "Lakefield" is a 10 nm SoC that's integrated much in the same way as today's ARM SoCs, which combine IP from various vendors onto a single PoP (package-over-package) Foveros die.

The biggest innovation with "Lakefield" is its hybrid x86 multi-core CPU design, which combines four Atom-class low-power cores, with one Core-class "Sunny Cove" core, in a setup akin to ARM's big.LITTLE. Low-power processing loads are distributed to the smaller cores, while the big core is woken up to deal with heavy loads. The SoC also integrates a Gen 11 iGPU core, partial components to accelerate 802.11ax WLAN, 5G, an PoP DRAM and NVMe storage devices. The reference motherboard based on "Lakefield" is barely larger than an M.2 SSD!

big.LITTLE is an innovation by ARM, which seeks to minimize power-draw on mobile devices. It is a sort of heterogeneous multi-core CPU design, in which a few "big" high-performance CPU cores work alongside a few extremely low-power "little" CPU cores. The idea here is that the low-power cores consume much lesser power at max load, than the high-performance cores at their minimum power-state, so the high-performance cores can be power-gated when the system doesn't need them (i.e. most of the time).

Intel finds itself with two distinct x86 implementations at any given time. It has low-power CPU micro-architectures such as "Silvermont," "Goldmont," and "Goldmont Plus," etc., implemented on low-power product lines such as the Pentium Silver series; and it has high-performance micro-architectures, such as "Haswell," "Skylake," and "Coffee Lake." The company wants to take a swing at its own heterogeneous multi-core CPU, according to tech stock analyst Ashraf Eassa, with the Motley Fool.
