Intel Celeron N4000 vs Intel Processor N250

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 Processor N250

The Intel Processor N250 is a mobile processor of the Twin Lake family which is mostly identical to Alder Lake-N, an architecture that will turn 4 in H2 2025. The chip is meant for entry-level laptops, tablets and mini PCs with no fans; it offers 4 Efficient (Gracemont) cores that run at up to 3.8 GHz, but no Performance cores. Compared to the N350, the N250 has a half as many CPU cores, resulting in a very significant (over 30%) performance loss. The iGPU is slightly slower here, too.

Gracemont E-cores do not support Hyper-Threading. No extra threads here.

Performance

Its multi-thread performance should be a few percentage points higher than older dual-core CPUs like the Core i3-10110U. Exact figures depend on the cooling solution and TDP settings of the system. Either way, this is a pretty slow chip that is only just fast enough for basic tasks.

Graphics

The SoC comes equipped with a Xe-architecture graphics unit with 32 EUs (Execution Units) running at up to 1.25 GHz. The iGPU can drive up to 3 UHD 2160p monitors and hardware-decodes AV1 among other popular video codecs. Due to the low number of Xe cores and the single-channel RAM restriction, gaming performance is only good enough for older games and fairly low resolutions. GTA V should be playable at 720p on Medium.

Architecture and Features

The integrated memory controller supports single-channel DDR4-3200, DDR5-4800 and LPDDR5-4800 RAM. PCIe NVMe SSD speeds are capped at 3.9 GB/s, corresponding to the PCIe 3 spec. There is no Thunderbolt / USB 4 support here, however, the latest Intel CNVi Wi-Fi 7 wireless networking modules are supported.

Its L3 cache is relatively small at 6 MB, and it has no proper NPU (and thus no Copilot+ branding).

Power consumption

The N250 is supposed to consume 6 watts when under longer loads. This is the Intel-recommended PL1 for the chip. No data on PL2 has been provided but values higher than 15 W are unlikely.

The SoC is manufactured using the second-generation 10 nm process marketed as Intel 7 meaning power efficiency isn't great here compared to the latest 3 nm silicon from the likes of Apple.
