Intel Core i3-8121U

Intel i3-8121U

The Intel Core i3-8121U is a power efficient entry-level dual-core processor for laptops. It is the first 10nm CPU from Intel and based on the new Cannon-Lake architecture. It offers 2 processor cores clocked at 2.2 (base) to 3.1 GHz (boost) and no integrated graphics card (therefore 2+0 setup according to Intel). Furthermore, a DDR4-2400 / LPDDR4/x-2400 memory controller (dual-channel, max. 41.6 GB/s, max. 32 GB) is integrated in the SoC.

First benchmarks show a similar performance to the higher clocked Intel Core i3-8130U (2.2 - 3.4 GHz, Kaby Lake, 14nm) and therefore in the entry level for laptops.

The CPU was introduced in the Lenovo IdeaPad-15ICN with a dedicated AMD Radeon RX 540 GPU and also in the Crimson Canyon NUC (also with a dedicated AMD GPU).
