"Twin Lake" is codename for a line of low-power x86-64 processors by Intel, which succeed the Core i3 N-series and N200 series "Alder Lake-N" processors. These non-socketed (BGA) chips power a wide range of devices from entry level notebooks and mini PCs to consumer NAS servers, and other embedded applications. The chips feature only E-cores. While "Alder Lake-N" used "Gracemont" cores, "Twin Lake" uses the swanky new "Skymont" cores, which serve as E-cores in "Lunar Lake" and "Arrow Lake" hybrid processors. "Skymont" cores feature massive IPC and clock-speed gains over "Gracemont," of nearly 50%, which pulls up their performance levels to match the "Golden Cove" and "Raptor Cove" P-cores of "Alder Lake" and "Raptor Lake," although these cores can't boost up to 5.00 GHz. We got the first name-drop of "Twin Lake" way back in May 2024. Jaykihn leaked what the processor lineup could look like.

The "Twin Lake" silicon features two "Skymont" E-core clusters sharing an L3 cache. At this point, the sizes of the shared L2 caches of the E-core clusters, and the size of the shared L3 cache are not known. On "Alder Lake-N," each "Gracemont" cluster features 2 MB of L2 cache, and the two clusters share a 6 MB L3 cache. The silicon also features an iGPU based on what is very likely the Xe-LPG graphics architecture, with four Xe cores worth 32 execution units (EU). The series is led by the Intel N355. This chip maxes out the "Twin Lake" silicon, enabling both "Skymont" clusters, for an 8-core/8-thread CPU configuration. The CPU comes with a base frequency of 3.00 GHz, and boosts up to 3.90 GHz. The chip comes with a configurable TDP of 9 W and 15 W. It comes with a maxed out iGPU, with all 32 EU being enabled, and a graphics frequency of 1.35 GHz.The Intel N350 is a significant step-down from the N355, and is meant for power constrained applications. It comes with a TDP of 7 W, but doesn't disable anything on the silicon—you get all 8 CPU cores, and a maxed out iGPU with all 32 EU enabled. The clock speeds take a beating, with the CPU base frequency being down to 2.60 GHz. The CPU boost frequency is still 3.90 GHz, but given its power constraints, it will rarely hit this frequency, on far fewer cores than the N355 does. The iGPU boost frequency remains unchanged at 1.35 GHz.

Next up, is the N250, a chip with a CPU core count of 4—an entire "Skymont" cluster is disabled. The CPU comes with a 3.20 GHz base frequency, and a 3.80 GHz CPU boost frequency. The iGPU is untouched—you get all 32 EU, but it boosts up to 1.25 GHz. The chip's TDP is down to 6 W.

Lastly, there's the Intel N150, an entry-level chip. It has the same CPU core count of 4, from disabling an E-core cluster. The iGPU goes below the knife too, with just 3 Xe cores or 24 EU being enabled. The CPU comes with a 2.90 GHz base frequency, and 3.60 GHz boost. The iGPU boosts up to 1.00 GHz. Much like the N250, this chip comes with a TDP of 6 W.
