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 a slightly higher clock speeds. 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 processor is not replaceable as it is directly soldered to the mainboard.

Architecture

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.

Performance

The CPU performance of the Celeron J4125 is in our tests similar to a mobile Pentium Silver N5000 (1.1 - 2.7 GHz Quad-Core at 6W). The performance is positioned in the lower entry level of processors of 2020. Still for basic tasks like office suits, browsing with moderate multitasking the processor performance should be fine.

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

Similar to the predecessor, Intel specifies the TDP with 10 Watts (versus 6 Watt for the mobile N4120 e.g.). The chip can therefore be cooled passively in theory, but SKUs with fans are possible as well.
