Intel Celeron J4005 vs Intel Celeron N5095A

Intel Celeron J4005

Der Intel Celeron J4005 ist ein sparsamer 2,0 GHz schneller Dual-Core-Prozessor auf Basis der neuen Gemini-Lake-Architektur und wurde Ende 2017 vorgestellt. Viele Features wie, AES, SHA und auch die Turbo Boost Funktionen bietet der kleine Einstiegs SoC. Im Turbo kann der Intel Celeron J4005 mit bis zu 2,7 GHz getaktet werden. Der SoC wird im 14-Nanometer-Prozesses mit FinFETs gefertigt und ist fest im System verbaut.

Die Änderungen im Vergleich zur Vorgängerserie zeigen sich auch beim L2-Cache, welcher nun mit 4 MB statt 2 MB, doppelt so groß ist. Alle neuen Gemini-Lake-SoCs unterstützen DDR4-RAM mit maximal 2.400 MHz (auch Low Power RAM).

Zum Einsatz kommen die neuen SoCs vor allem im Einstiegssegment. So werden günstige Mini-ITX Mainboards und Mini-PCs im zu finden sein, welche die neuen stromsparenden Prozessoren beheimaten. Aber auch om Destktop-Segment wird Intel die aktuellsten NUC mit den heuen SoCs ausstatten.

Mit der Intel UHD Graphics 600 bietet der Prozessor eine integrierte Grafikeinheit. Beim Intel Celeron J4005 bietet die Intel UHD Graphics 600 12 EUs und taktet mit 250 MHz bis 700 MHz.

Architektur

Die Prozessor-Architektur der Gemini Lake SoCs wurde im Vergleich zum Vorgänger leicht weiterentwickelt. Intel nennt sie nun Goldmont Plus Kerne und verdoppelt den Level 2 Cache von 2 auf 4 MB. Trotzdem sollte die Pro-MHz-Leistung noch deutlich hinter den aktuellen Kaby-Lake Prozessoren bleiben.

Intel Celeron N5095A

The Celeron N5095A is an inexpensive quad-core SoC of the Jasper Lake product family designed for use in affordable SFF desktops and laptops. It features four Tremont CPU cores running at 2 GHz that Boost to up to 2.9 GHz with no thread-doubling Hyper-Threading technology in sight. A pretty basic iGPU is present as well.

The only difference between the N5095A and the N5095 is that the former comes with support for more proprietary Intel technologies such as the Smart Sound DSP, Wake on Voice and HD Audio.

Architecture and Features

Tremont brings many improvements over Goldmont Plus, the architecture that we know from the N5030 and myriads of other N-class CPUs. An up to 30% boost in single-thread performance is to be expected thanks to smarter prefetchers, branch prediction improvements and other refinements, according to Intel. These new chips are physically larger than their immediate predecessors as a result. Either way, this is still a "small" core rather than a "big" one according to ChipsAndCheese.

The Celeron has 1.5 MB of L2 and 4 MB of L3 cache and is compatible with DDR4-2933 and LPDDR4x-2933 memory or slower. Support for Intel CNVi Wi-Fi 6 modules is baked into the chip, as are 8 PCIe 3.0 lanes for NVMe SSD speeds up to 3.9 GB/s. USB 4 or Thunderbolt aren't supported however.

Please also note that the Celeron gets soldered to the motherboard (BGA1338 socket interface) for good and is thus not user-replaceable.

Performance

While we haven't tested a single system featuring the N5095A as of Sep 2024, we have done several reviews of computers/laptops powered by the N5095. CPU performance should be pretty much identical between the two. Therefore, we fully expect the chip to be about as fast as the Core i3-10110U, Core i3-1005G1, Celeron N5105 and also the Ryzen 3 3200U in multi-threaded workloads. Which is just enough for the most basic of tasks in late 2024.

Performance will get a significant hit if the power target is set to 10 W or 6 W instead of the Intel-recommended 15 W value.

Graphics

The DirectX 12.1-capable 16 EU UHD Graphics runs at up to 750 MHz and is in many respects similar to what Ice Lake CPUs come equipped with. This graphics adapter is capable of driving up to 3 SUHD displays simultaneously; HEVC, AVC, VP9, MPEG-2 and other popular video codecs can all be hardware-decoded. AV1 and VVC can't.

As far as gaming is concerned, it is reasonable to expect playable framerates in really old games (like Dota 2 Reborn) provided one sticks to lower resolutions such as HD 720p.

Power consumption

While most N-class chips have a 6 W long-term power target, the Celeron N5095A has a 15 W TDP to mimic much faster U-class Core processors. This isn't a great CPU for passively cooled designs.

The N5095A is built with the same 10 nm Intel process as Ice Lake-U processors for pretty unimpressive power efficiency, as of late 2024.
