Intel Celeron N4120 vs Intel Core i5-1235U
Intel Celeron N4120
► remove from comparison
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.
Intel Core i5-1235U
► remove from comparison
The Intel Core i5-1235U is a mid-range mobile CPU for thin and light laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 2 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 12 supported threads when combined with the E-cores. The clock rate ranges from 1.3 to 4.4 GHz on the performance cluster and 0.9 to 3.3 GHz on the efficient cluster. 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 12 MB L3 cache. Compared to the i5-1245U, the 1235U offers lower base clock speeds and only "Essentials" vPro management features. Compared to the P-series (28W) or H-series (45W), the 15W TDP may limit the sustained performance.
Performance
The average 1235U in our database is in the same league as the Ryzen 5 PRO 5650U and also, surprisingly enough, the i7-1250U and the i7-1260U, as far as multi-thread benchmark scores are concerned. This is a very respectable result, as of mid 2023.
Thanks to its decent cooling solution and a long-term CPU power limit of 27 W, the Beelink SEi12 is among the fastest systems built around the 1235U that we know of. It can be twice as fast in CPU-bound workloads as the slowest system featuring the same chip in our database, as of August 2023.
Architecture
The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).
The integrated graphics card is based on the Xe-architecture and offers 80 of the 96 EUs (Execution Units) operating at up to 1.2 GHz.
Power consumption
This ULV processor has a Base power consumption of 15 W (also known as the long-term power limit), with 55 W being its maximum Intel-recommended Turbo power consumption. Both values are too high to allow for passively cooled designs.
Core i5-1235U is manufactured on Intel's fourth-gen 10 nm process marketed as Intel 7 for decent, as of mid-2022, energy efficiency.
