Intel Celeron N4100 vs Intel Celeron N5100

Intel Celeron N4100

The Intel Celeron N4100 is a quad-core SoC primarily for inexpensive notebooks and was announced late 2017. It runs at 1.1-2.4 GHz (Single Core Burst, Multi Core Burst max 2.3 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, 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 permanently 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 N4100 in our database directly competes with AMD's 3020e and 3050e, as far as multi-thread benchmark scores are concerned. The Intel Core m3-8100Y and the Celeron 6305 are close nearby as well. Routinely described as "entry-level" in 2019 and 2020, the Celeron N4100 is a slow processor that is good for the most basic tasks only such as Web browsing with no more than two or three tabs open at a time.

The LapBook Pro is among the fastest systems built around the N4100 that we know of. It can be around 50% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

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 700 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

Celeron N4100 has a default TDP of 6 W (also known as PL1), making it a great option for passively cooled setups.

The fairly old 14 nm process this Celeron is built with makes for so-so, as of mid-2022, energy efficiency.

Intel Celeron N5100

The Intel Celeron N5100 is a quad-core SoC of the Jasper Lake series that is primarily intended for inexpensive notebooks and was announced in early 2021. The four Tremont CPU cores clock between 1.1 and 2.8 GHz (single core Burst) and offer no HyperThreading (SMT). The N5100 uses 1.5 MB L2 and 4 MB L3 cache. The chip is manufactured in 10nm at Intel (most likely in the same process as Ice Lake).

Architecture

The processor architecture is called Tremont and a complete redesign compared to the old Golmont Plus cores in the predecessor. According to Intel, the single thread performance of a core could be improved by 30% on average (10 - 80% in all tests of SPECint and SPECfp).

Features

In addition to the quad-core CPU block, the SoC integrates a 24 EU Intel UHD Graphics GPU clocked from 350 - 800 MHz and a LPDDR4(x) dual channel memory controller (up to 16 GB and 2933 MHz). The chip now also partly integrates Wi-Fi 6 (Gig+), 8 PCIe 3.0 lanes, 14 USB 2.0/ 3.2 ports and two SATA 6.0 ports. The package got bigger and measures 35 x 24 mm (compared to 25 x 24 mm for the N5030 e.g.). The SoC is directly soldered to the mainboard (BGA) and can't be easily replaced.

Performance

While we have not tested a single system powered by the N5100 as of August 2023, it's safe to expect the chip to be 10% to 20% slower than the N6000, as far as multi-thread performance is concerned. In other words, this is a fairly slow processor that is unlikely to make anybody happy.

Power Consumption

Like most other N-class Intel processors, this Celeron has a 6 W default TDP (also known as the long-term power limit). This is rather low; a small metal plate is all it takes to dissipate heat generated by such a CPU.

The Celeron N5100 is manufactured on Intel's first-generation or second-generation [no exact data available] 10 nm process for average, as of early 2023, energy efficiency.
