Intel has finally detailed the Lakefield family of processors based on the Foveros 3D packaging tech. The current Lakefield lineup includes the Core i3-L13G4 and the Core i5-L16G7, which are 7 W penta-core parts featuring a 10nm Sunny Cove and four 10nm Tremont cores. Intel Lakefield is available in the Samsung Galaxy Book S and will also power the upcoming Lenovo ThinkPad X1 Fold and the Microsoft Surface Neo.

After an initial preview at CES 2019, Intel has been relatively quiet about the Foveros-based Lakefield processors officially called Core processors with Intel Hybrid Technology. Apart from a few leaked benchmarks, not much was known about the processors themselves. Today, Intel is officially announcing the arrival of Lakefield Hybrid processors. 

Intel already had detailed about the Foveros 3D packaging technology last year. Essentially, Foveros allows a mix and match of various memory and I/O components into what is called a Compute Chiplet that includes the CPU, GPU, LPDDR4x memory controller, the DRAM itself, 1.5 MB L2 cache, 0.5 MB medium level cache, and a 4 MB L3 cache. 

The CPU cores are comprised of a big 10nm Sunny Cove core for intensive workloads and four smaller 10nm Tremont cores for power efficiency with the Windows scheduler deciding the load allocation to the cores. Intel is pegging the Lakefield chips as an alternative to Y-series processors such as Amber Lake-YIntel claims up to 12% faster performance in single-threaded integer compute loads (when the Core i5-L16G7 is compared to an Core i7-8500Y). Intel says Lakefield SoCs consume just about 2.5 mW of power in standby — 91% lesser than the Core i7-8500Y. These processors also feature dual internal display pipes making them an ideal choice for foldable and dual-screen PCs.

The Lakefield family is comprised of two SKUs: the Core i3-L13G4 and the Core i5-L16G7. While we have also seen the Core i5-L15G7 in leaked benchmarks, Intel has not detailed it in today's launch. It could be very well possible that the Core i5-L15G7 was just a prototype sample.

SKU Cores/Threads Base Freq. (GHz) Single-core Boost Freq. (GHz) All-core Boost Freq. (GHz) GPU GPU Boost Freq. (GHz) Cache TDP Memory
Core i3-L13G4 5/5 0.8 2.8 1.3 UHD Graphics 48 EUs 0.5 4 MB 7 W LPDDR4X-4267
Core i5-L16G7 5/5 1.4 3.0 1.8 UHD Graphics 64 EUs 0.5 4 MB 7 W LPDDR4X-4267

Both Lakefield SKUs offer Gen11 UHD Graphics with the Core i3-L13G4 featuring 48 Execution Units (EUs) and the Core i7-L16G7 offering 64 EUs. According to Intel, Lakefield can offer up to 54% faster video conversion on Handbrake (Core i5-L16G7 compared to the Core i5-8200Y), is about 1.7x faster than the Core i7-8500Y in 3DMark 11, and can support up to four external 4K displays. Wi-Fi 6 and LTE connectivity are supported. Do note that these are Intel's figures and we look forward to testing laptops powered by Lakefield to know the exact benefits that can be expected when compared to previous generation 7 W parts.

There aren't too many Lakefield-powered devices available, though. Samsung recently announced the Galaxy Book S while Lenovo had earlier showcased the ThinkPad X1 Fold at CES 2020, which will be available later this year. Also coming this Holiday is the Microsoft Surface Neo dual-screen tablet device. The inclusion of Lakefield in the Surface Neo that runs Windows 10X does open-up exciting possibilities for enhanced on-the-go productivity. 

It is not yet known if other OEMs would also hop on to the Lakefield bandwagon, but we expect some traction once the current devices prove themselves for the advertised mobility advantages.
