Intel Celeron J4125

The Intel Celeron J4125 is a quad-core SoC primarily for inexpensive mini PCs and was announced late 2019. It runs at 2-2.7 GHz (Single Core Burst) and is based on the Gemini Lake platform (2019 refresh). Compared to the predecessor, the refresh offers slightly higher clock speeds. Similar to the Apollo Lake predecessors, the chip is manufactured on a 14 nm process with FinFETs but offers slightly improved processor cores, double the amount of L2 cache, partial Wi-Fi 5 support, all in a smaller package. 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 processor is not replaceable as it is directly soldered to the mainboard.


The processor architecture is 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 J4125 in our database is only just able to creep in front of AMD 3050e, a dual-core, Zen-based, entry-level processor of nearly the same energy efficiency, as far as multi-thread performance is concerned. That renders the Celeron a very basic CPU that's good for basic day-to-day activities only.

GPU Performance

The UHD Graphics 600 (Gemini Lake) is based on Intel's Gen9 architecture, which supports DirectX 12 and is also used for the Kaby Lake / Skylake / Apollo Lake graphics adapters (like HD Graphics 520). Equipped with 12 EUs and a clock of up to 750 MHz, the performance should be roughly on par with the older HD Graphics 500 (Apollo Lake).

The chip also includes an advanced video engine with hardware support for the playback of VP9 and H.265 material (8-bit color-depth).

Power consumption

Much like almost all other J-class Intel processors, the Celeron has a default TDP of 10 W (also known as the long-term power limit). It is built with a fairly old, as of early 2023, 14 nm Intel process making for subpar energy efficiency.
