Intel Celeron N4020 vs Intel Celeron N4000
Intel Celeron N4020► remove from comparison
The Intel Celeron N4020 is an energy-efficient, dual-core processor (SoC) of the Gemini Lake Refresh product family; as such, it is designed for use in laptops and mini-PCs of the most affordable flavor. The Celeron was launched in Q4 2019. Its CPU cores run at 1.1 GHz to 2.8 GHz, the latter being a moderate 200 MHz upgrade over the preceding N4000 chip. Other key specs include a DDR4/LPDDR4 memory controller (up to 2,400 MHz and up to 8 GB, with independent reports claiming as much as 32 GB will work just fine) and the integrated UHD Graphics 600 graphics adapter.
Just like Apollo Lake family products, the ever-popular N3350 included, Celeron N4020 is manufactured by Intel on a 14 nm process. What makes these newer Celerons different are the slightly improved processor cores with double the L2 cache and also, somewhat counterintuitively, their smaller chip area.
The Goldmont Plus microarchitecture is familiar to us from Gemini Lake processors like the N4000. A moderately large 4 MB L2 cache features prominently on the rather short list of Goldmont Plus' strong sides, allowing for a marginal increase in performance-per-MHz figures compared to Goldmont. Still, Gemini Lake Refresh processors are a clear step-down from the Core i3/i5/i7/i9 series processors, both in performance and in features.
N4020 has six PCI-Express 2.0 lanes at its disposal. While very few N4020-based SBCs, nettops and laptops feature an NVMe M.2 slot, you can use an NVMe SSD as a boot drive with this processor (read/write rates will be limited to 2 GB/s though). Furthermore, partial Wi-Fi 5 support is built into the CPU. The Celeron also supports up to eight USB 3.0 ports and two SATA III storage devices.
Please note this is not a user-replaceable CPU. They solder it straight on to the motherboard for good (FCBGA1090 socket interface).
While slightly faster than the outgoing Celeron N4000, this is a very unimpressive CPU no matter how you slice it. As fat as multi-thread performance is concerned, the average Celeron N4020 in our database barely manages to outgun the i5-4210Y, a processor of nearly the same energy efficiency that was launched so many years ago (in 2013, to be exact). Qualcomm Snapdragon 7c and Intel Celeron N4500 are close nearby as well. All in all, per-thread and per-MHz performance of Gemini Lake Refresh processors are nothing to write home about, rendering them usable for basic tasks only such as word processing and web browsing with just two or three tabs open.
It is worth noting that Intel Celeron N4120, a quad-core processor with a similar name, has little trouble leaving the dual-core N4020 behind in most workloads - which is not to say it is a fast CPU.
Just like HD Graphics 500, the UHD Graphics 600 supports DX 12 and has 12 EUs clocked at up to 650 MHz. The Iris Plus G7 iGPU that certain 10th Gen Ice Lake processors have packs 64 EUs, for reference. As a low-end solution, UHD Graphics 600 will let you play some seriously old titles, but that's about it.
Perhaps more importantly, this graphics solution will let you run up to 3 monitors with resolutions as high as [email protected] Furthermore, it will have no trouble HW-decoding AVC, HEVC and VP9 videos. The newer AV1 codec will be decoded via software, with the limited CPU horsepower imposing a hard limit on the video resolution that can be played back without stuttering. 1080p60 YouTube videos are out of reach while 720p25 videos run fine, to give you an example.
The low 6 W TDP (also known as the Power Limit 1) makes it easy to ditch the fan. While the Celeron can indeed be cooled passively with almost no issues, its performance sustainability will be anything but decent unless the long-term Power Limit is set to a value higher than the default 6 W and a fan is available to aid in heat dissipation.

The Intel Celeron N4000 is a dual-core SoC designed for affordable laptops and mini-PCs and was announced late 2017. It runs at 1.1 GHz to 2.6 GHz (Single Core Burst, Multi Core Burst maxes out at 2.5 GHz) and is based on the Gemini Lake platform. Similar to the Apollo Lake predecessor, the chip is manufactured on a 14 nm process with FinFETs but offers slightly improved processor cores, double the amount of L2 cache, all in a smaller package. Partial Wi-Fi 5 support is baked into the chip. Besides two 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 was slightly reworked and is now called Goldmont Plus. It features a larger L2 cache (4 MB). That means the per-clock-performance should be a bit better, but not anywhere near the Core CPUs like Kaby Lake Y.
The average N4000 in our database only just matches Intel Core i5-4300Y, a dual-core processor of nearly the same energy efficiency, in multi-thread performance. This renders the Celeron a very slow processor for all but the most basic of uses, providing for long load times and generlly painful user experience.
The UHD Graphics 600 (Gemini Lake) is based on Intel's Generation 9 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 650 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 (8-bit color-depth).
Just like most other N-class Celerons and Pentiums, Celeron N4000 has a 6 W TDP (also known as the long-term power limit). The short-term power limit can be as high as 15 W. This will obviously differ a lot between various systems. Last but not the least, this Celeron is manufactured on an old 14 nm process for poor energy efficiency.
