The Intel Celeron N4120 is a quad-core SoC primarily for inexpensive notebooks and was announced late 2019. It runs at 1.1-2.6 GHz (Single Core Burst) and is based on the Gemini Lake platform. Compared to the predecessor, the Celeron N4100, the refresh offers a 200 MHz higher Boost clock. Similar to the Apollo Lake predecessors, the chip is manufactured in a 14 nm process with FinFETs but offers slightly improved processor cores, double the amount of L2 cache, a smaller package, a new generation of monitor outputs (Gen 10) and a partly integrated WiFi chip. Besides four CPU cores, the chip also includes a DirectX 12 capable GPU as well as a DDR4/LPDDR4 memory controller (dual-channel, up to 2400 MHz). The SoC is not replaceable as it is directly soldered to the mainboard.
The processor architecture ist still called Goldmont Plus. Compared to the older Goldmont cores in Apollo Lake, they feature an increased level 2 cache (to 4 MB). That means the per-clock-performance should be a bit better, but not near the Core CPUs like Kaby Lake Y.
The average N4120 in our database is not much faster than AMD's Zen-based, affordable and energy-efficient Athlon Silver 3050e dual-core processor, as far as multi-thread loads are concerned, with Intel Celeron 6305 and Intel Core i5-7Y54 also sitting close nearby. It's a very basic CPU we're talking about here. While it does have four cores, these are slow cores, dashing hopes of anyone looking to get a Core i3-like performance for cheaper.
The chip also includes an advanced video engine with hardware support for the playback of VP9 and H.265 material (8-bit color-depth).
Just like most other N-class Intel processors, Celeron N4120 has a default TDP of 6 W (also known as PL1), making it a good option for passively cooled laptops, tablets, mini-PCs. It's manufactured on a very old (as of late 2022) 14 nm process, though, making for poor energy efficiency.
