The Core i5-L16G7 is a SoC with 5 processor cores based on the Lakefield architecture. It uses one fast Sunny Cove core (known from Ice-Lake CPUs but without AVX512) with up to 3 GHz and 4 small Tremont cores (Atom / Celeron) with up to 2.8 GHz. Using all 5 cores, the CPU can reach up to 1.8 GHz, base clock speed is 1.4 GHz. The CPU does not support HyperThreading / SMT. The rest of the SoC is similar to the Ice Lake chips, like the Gen 11 graphics card with 64 EUs (similar to the Iris Plus G7 but only clocked at 500 MHz and using the UHD Graphics name).
According to Intel, the L16G7 should be around 24% faster in multi threaded applications and 12% faster in single threaded applications compared to the old Core i7-8500Y (Amber Lake-Y, 2 cores, 1.5 - 4.2 GHz). That means it should be slightly slower than the Core i3-8130U.
With a specified TDP of 7 Watt (PL1, 9.5 Watt PL2), the CPU is well suited for thin and light laptops and Windows based tablets. / 2-in-1. Intel claims that the standby power was greatly reduced (91% better compared to the i7-8500Y with 2.5 mW). The SoC is manufactured in 10nm and uses the Intel Foveros 3D Packaging technology. Foveros is used to stack the in 22FFL manufactured I/O die, the compute die in 10nm and up to 8 GB LPDDR4X-4267.
