Intel Processor N100 vs Intel Celeron N3350

Intel Processor N100

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).

Intel Celeron N3350

The Intel Celeron N3350 is an Apollo Lake family, dual-core, ultra-low-power processor (SoC) that saw the light of day in 2016. Its two cores run at 1.1 GHz to 2.4 GHz; these are not Hyper-Threading-enabled meaning there are no additional threads. This chip has a fairly competent integrated graphics solution, the Intel HD Graphics 500, and eats very little (~6 W).

Amusingly enough, Intel keeps making and selling the Celeron as of late 2022, albeit the price has dropped from about $100 to about $20 per unit making the CPU even more popular with ultra-budget nettop and laptop makers.

Architecture & Features

Just like other Celeron N, Celeron J, Pentium N, Pentium J processors, this Celeron is notable for its small die size. It is easy to manufacture, lowering the costs and enabling Intel to compete with various ARM-based products (hello, Raspberry Pi).

The Celeron N3350 features the Goldmont CPU microarchitecture. This replaces the dated Silvermont (2013), bringing with it several welcome improvements and making for a double-digit IPC improvement. There is still no L3 cache to be found here, however, it now takes less cycles to perform many operations.

The Celeron is compatible with DDR3L-1866, LPDDR3-1866, LPDDR4-2400 RAM. Intel's guidelines state that up to 8 GB are supported; that being said, various forum users report that the CPU functions just fine if mated to 16 GB and even 32 GB of RAM. The chip features six PCI-Express 2.0 lanes for connecting various devices, meaning a four-lane NVMe SSD will not be able to deliver a data transfer rate of more than 2 GB/s. eMMC and SATA storage is supported natively, too.

This Intel CPU is Secure Boot-compatible; technically, it will have no issue running 64-bit Windows 11. However, Microsoft only allows Windows 11 to be installed on systems with CPUs released in 2017 or later, making 64-bit Windows 10 the only OS that the Celeron is officially compatible with.

Last but not the least, please keep in mind that this is not a user-replaceable CPU. It gets permanently soldered to the motherboard (BGA1296 socket interface).

Performance

The average N3350 in our database is just as fast as the Atom x5-Z8300 and the Core 2 Duo SU7300, as far as multi-thread benchmark scores are concerned. Which is not fast at all. In fact, the two cores of this Celeron trail behind a single core of any half-decent CPU such as Intel's very own Core i3-7130U. A proper x86 CPU, Celeron N3350 will let you run nearly any Windows app, the caveat being that you will have to wait for several seconds every time you click on something. Windows 10 takes nearly a minute to fully boot with this CPU.

Graphics

The Intel HD Graphics 500 (Apollo Lake) is the highlight of this little Celeron. As far as the feature set is concerned, the HD Graphics 500 is not much different from the HD Graphics 520 or any other graphics adapter that full-blown six-generation Intel Core i3/i5/i7 chips have. This iGPU is compatible with DX12; it will drive up to 3 monitors with resolutions as high as 2160p60. It will happily decode VP9 and AVC-encoded videos, too. These are the two codecs that YouTube mostly relies on, as of 2021.

It's not all roses and sunshine. To keep power consumption under control, the number of Execution Units was reduced to 12 (the HD Graphics 520 has 24 EUs at its disposal, for reference). Besides, the UHD Graphics runs at up to 650 MHz which is not a lot. Very few games will be playable on this graphics solution - mostly, ones that were released in the 2000s or even in the 1990s.

Power consumption

The Celeron's default TDP (also known as the Power Limit 1) is 6 W, making it a great option for passively cooled systems. Increasing the PL1 by one or two watts, which many systems built around Apollo Lake allow one to do, makes for a much more responsive user experience, speaking subjectively.

Energy efficiency isn't great here, as Intel's 14 nm processes are very old as of mid 2022.
