Intel Atom N455 vs Rockchip RK2918 1.2 GHz vs HiSilicon Kirin 9000W

The Intel Atom N455 is a small and cheap entry level CPU for Netbooks and small laptops. In the package is an integrated memory controller for DDR3 main memory (the difference to the Atom N450) and the GMA 3150 graphics card. 

The performance of the whole system (Atom N455 and integrated GMA 3150) is only sufficient for basic tasks like surfing the web, or office working. HD video, video cutting, advanced photo editing, multitasking and of course gaming may overstrain the GPU and CPU. Compared to the previous Atom generation, the performance gain is only marginally above a similar clocked Atom N280 / GMA 950.

An advantage of the combination, is the small overall power consumption of the CPU, GPU and memory controller (only 6.5 Watt TDP). Intel states 20% power reduction and 60% package reduction. Therefore, the chip is ideally used in small Netbooks, MIDs, and thin laptops. Compared to the Z500 series combined with the US15W chipset (2.4+2.3 W), the power consumption is similar.

The HiSilicon Kirin 9000W is an SoC that can be used in smartphones and tablets based on Android and was first installed in the Huawei MatePad Pro 13.2.

Huawei does not reveal any information about the SoC. The little information that is available comes from benchmarks and system analysis tools. The CPU consists of three clusters with a total of 12 cores. The power-saving cluster has four ARM Cortex-A510 cores, each operating at up to 1,530 MHz, while six other cores use unspecified cores from HiSilicon (0x0D42) and clock at up to 2,150 MHz. The third cluster contains two HiSilicon cores (0x0D02), each with a maximum clock speed of 2,487 MHz. The performance cores could possibly be based on the TaiShan V120 architecture (as in the Kirin 9000S).

The single-core performance is correspondingly mixed, but the multi-core performance is at the level of a high-end SoC from 2022 due to the numerous cores.

A Maleoon 910 by HiSilicon is integrated as the graphics unit, similar to the 9000S (where it was clocked with up to 750MHz).

Nothing concrete is known about the manufacturing process or the architecture. The SoC will probably be manufactured in 7 nm at SMIC.
