The Intel Processor N100 is an entry-level mobile CPU for thin and light laptops from the Alder Lake-N series. It was announced in early 2023 and offers no performance cores and 4 of the 8 efficient cores (E-cores, Gracemont architecture). The chip does not support HyperThreading and clocks with 1 to 3.4 GHz. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 6 MB L3-cache.
Performance
The average N100 in our database delivers unimpressive multi-thread benchmark scores that are most similar to those of the Core i3-1115G4. The chip is fast enough for many day-to-day tasks, but not much more than that; the other thing to keep in mind is that of the two N100-toting systems tested by us as of October 2023, both have rather high CPU power limits. The chip will be noticeably slower if limited to just six or seven Watts.
Features
The Alder Lake-N chips only support single channel memory with up to DDR5-4800, DDR4-3200 or LPDDR5-4800. The chip also supports Quick Sync and AV1 decoding (most likely same engine as in Alder Lake). Furthermore, Wi-Fi 6E and Bluetooth 5.2 are partly integrated (but no Thunderbolt). External chips can be connected via PCIe Gen3 x9 (via the PCH).
The integrated graphics adapter is based on the Xe-architecture and offers only 24 of the 32 EUs (Execution Units) operating at only 450 - 750 MHz. Due to the single channel memory, low clock speeds, and low shader count, the gaming performance of the iGPU is very limited.
Power consumption
The N100 has a base power consumption of only 6 W and is therefore suited for fanless cooling. The CPU is built with a further improved 10nm SuperFin process at Intel (called Intel 7).
The Intel Celeron N4120 is a quad-core SoC primarily for inexpensive notebooks and was announced late 2019. It runs at 1.1-2.6 GHz (Single Core Burst) and is based on the Gemini Lake platform. Compared to the predecessor, the Celeron N4100, the refresh offers a 200 MHz higher Boost clock. 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 SoC 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 average N4120 in our database is not much faster than AMD's Zen-based, affordable Athlon Silver 3050e, as far as multi-thread benchmark scores are concerned, with the Intel Celeron 6305 and the Core i5-7Y54 found close nearby as well. It's a very basic CPU that we're talking about here. While it does have four cores, these are some seriously slow cores, dashing hopes of anybody looking to get a Core i3-like performance for cheap.
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 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
Just like most other N-class Intel processors, Celeron N4120 has a default TDP of 6 W (also known as PL1), making it a good option for passively cooled laptops, tablets, mini-PCs. It's manufactured on a very old (as of late 2022) 14 nm process, though, making for poor energy efficiency.
The Intel Celeron N4020 is a slow 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 an integrated UHD 600 graphics adapter.
Architecture & Features
Just like Apollo Lake family products, the ever-popular N3350 included, the N4020 is manufactured on a really old, as of late 2023, 14 nm process. What makes the newer Celerons different are the slightly improved processor cores with double the L2 cache and also, somewhat counterintuitively, a reduction in physical size.
The Goldmont Plus microarchitecture is not much different from what was used in Gemini Lake processors like the N4000. A relatively large 4 MB L2 cache features prominently on the rather short list of N4020's strong sides, allowing for a marginal increase in performance-per-MHz figures compared to processors of previous generations. Still, Gemini Lake refresh processors are a clear step down from Core i3/i5/i7/i9 series processors, both in performance and in features.
The 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 to the motherboard for good (BGA1090 socket interface).
Performance
While slightly faster than the outgoing Celeron N4000, the average N4020 in our extensive database only just manages to match the N6211, as far as multi-thread performance is concerned. These three chips deliver multi-thread CB R15, CB R20 and CB R23 scores that are so low, they lag behind a single-thread score of any half-decent CPU such as an i5-1135G7. In other words, these Celeron N chips are good enough for basic tasks only such as word processing and Web browsing with two or three tabs open at a time.
The Celeron N4120, a quad-core chip with a similar name, has little trouble leaving the N4020 behind in most workloads - which is not to say it is a fast CPU.
Jacking the long-term power limit value up to something like 9 W will help improve system responsiveness noticeably.
Graphics
The UHD Graphics 600 is based on Intel's Generation 9 architecture, much like the HD Graphics 520 or the UHD Graphics 615 or other widespread Intel iGPUs found in Core i3/i5/i7/i9 processors of generations six to ten.
Just like the HD Graphics 500, the UHD Graphics 600 is DX12 compatible. The iGPU's 12 EUs can run 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 as far as its talents go.
Perhaps more importantly, this graphics solution can drive up to 3 monitors with resolutions as high as 4096x2160@60. Furthermore, it will have no trouble HW-decoding AVC, HEVC and VP9-encoded videos. The newer AV1 codec will be decoded via software, with the limited CPU horsepower imposing a limit on video resolutions that can be played back without stuttering. 1080p60 videos are out of reach while 720p25 videos run fine, to give you an example.
Power consumption
The low 6 W TDP (also known as the long-term Power Limit) makes it easy for laptop makers to ditch the fan. Performance sustainability will be poor 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 Celeron N4020 is built with one of the old 14 nm Intel processes for poor, as of mid 2023, energy efficiency.
