Intel Celeron N4000 vs Intel Celeron J4025 vs Intel Pentium Silver N5000

Intel Celeron N4000

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.

Architecture

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.

Performance

The average N4000 in our database only just matches the Core i5-4300Y, a fairly old dual-core processor of nearly the same energy efficiency, in multi-thread performance. In other words, the Celeron is a very slow processor that's good enough for the most basic of tasks only. Expect long load times no matter the app.

Graphics

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).

Power consumption

Like most other N-class Intel chips, the Celeron N4000 has a 6 W TDP (also known as the long-term power limit). This is not much at all, allowing laptop makers to build passively cooled laptops, tablets, mini-PCs around the chip. The SoC can briefly consume up to 15 W, though, depending on how a system is configured.

Last but not the least, this Celeron is manufactured on one of the old 14 nm Intel processes leading to poor, as of early 2023, energy efficiency.

Intel Celeron J4025

The Intel Celeron J4025 is an energy-efficient, dual-core processor (SoC) of the Gemini Lake Refresh product family; as such, it is designed for use in mini-PCs of the most affordable flavor. The Celeron was launched in Q4 2019. Its CPU cores run at 2 GHz to 2.9 GHz (single core boost). 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.

Architecture

Just like Apollo Lake family products, the ever-popular N3350 included, Celeron J4025 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.

J4025 has six PCI-Express 2.0 lanes at its disposal. While very few J4025-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).

Performance

The Celeron J4025 is positioned in the lower entry level and only slightly faster than the mobile Celeron N4020. Therefore, it is best suited for basic tasks like word processing and web browsing with just two or three tabs open.

Graphics

The UHD Graphics 600 is based on Intel's Generation 9 architecture, much like HD Graphics 520 or UHD Graphics 615 or so many other widespread Intel iGPUs.

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 4096x2160@60. 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.

Power Consumption

As a J-series CPU, the TDP is rated at 10 Watts and therefore 4 W higher than the mobile N4020. 

Intel Pentium Silver N5000

The Intel Pentium Silver N5000 is a quad-core SoC primarily for inexpensive notebooks and was announced late 2017. It runs at 1.1-2.7 GHz (Single Core Burst, Multi Core Burst max. 2.6 GHz) and is based on the Gemini Lake platform. Similar to the Apollo Lake predecessor, 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.

Architecture

The processor architecture was slightly reworked and is now called Goldmont Plus. It features 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 average N5000 in our database is in the same league as the AMD 3050e and the Pentium 4415U, as far as multi-thread benchmark scores are concerned. This is a really poor result, as of Q3 2023.

The Yoga 330-11IGM is among the fastest laptops featuring the N5000 that we know of. It can be more than 30% faster in CPU-bound workloads than the slowest system built around the same chip in our database, as of August 2023.

GPU Performance

The UHD Graphics 605 (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 18 EUs and a clock of up to 750 MHz, the performance should be roughly on par with the older HD Graphics 5300 and HD Graphics 505 (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 6 Watts (SDP 4.8 Watts – Scenario Design Power). The chip can therefore be cooled passively in theory, but SKUs with fans are possible as well.
