Intel Processor N150 vs Intel Celeron N5105

Intel Processor N150

The Intel Processor N150 is the slowest mobile processor of the Twin Lake family. Twin Lake is mostly identical to Alder Lake-N, an architecture that will turn 4 in H2 2025. The N150 is meant for entry-level laptops, tablets and mini PCs with no fans; it offers 4 Efficient (Gracemont) cores that run at up to 3.6 GHz, but no Performance cores. Compared to the N250, the N150 has a significantly slower iGPU and slightly lower CPU clock speeds.

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

Performance

Its multi-thread performance should be about as good as 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 24 EUs (Execution Units) running at up to 1.0 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 very old games and low resolutions such as XGA 1024 x 768.

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 N150 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.

Intel Celeron N5105

The Intel Celeron N5105 is a quad-core SoC of the Jasper Lake series that is primarily intended for inexpensive desktops and was announced in early 2021. The four Tremont CPU cores clock between 2 and 2.9 GHz (single core Burst) and offer no HyperThreading (SMT). The N5105 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).

CPU 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 450 - 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

The average N5105 in our database is in the same league as the Core i3-1005G1 and the Ryzen 3 3250U, as far as multi-thread benchmark scores are concerned. Your mileage may vary depending on how high the CPU power limits are.

Power Consumption

Similar to the predecessor, Intel specifies the TDP with 10 Watts (mobile and lower clocked N5100 6W). The chip can therefore be cooled passively in theory, but SKUs with fans are possible as well.
