Mediatek Kompanio Ultra 910

Mediatek Kompanio Ultra 910

The MediaTek Kompanio Ultra 910 is a high-end ARM based SoC for Chromebooks. The Chip is similar to the Mediatek Dimensity 9400 for smartphones, but without a 5G modem and a deactivated GPU core.

The CPU no longer uses classic energy-saving cores, but the second generation of the "all big core design". In this case, there is one ARM Cortex-X925 with up to 3.62 GHz, three Cortex-X4 with up to 3.25 GHz and four Cortex-A720 with up to 2 GHz. The manufacturer has also increased the level 3 and SLC cache compared to its predecessor, which now has a capacity of 22 MB (12 MB L3 + 10 MB system cache).

The integrated ARM Immortalis-G925 with 11 cores is responsible for graphics calculations. Performance and energy efficiency are said to have improved by up to 44%.

The performance in Geekbench 6.4 is comparable with the Mediatek Dimensity 9400. Compared to a current notebook processor from Intel such as the Core Ultra 5 135U the single-core performance is slightly better, but the multi-thread performance is slightly worse.

The MediaTek NPU 890 is responsible for AI calculations.

The SoC is manufactured using the 3-nanometer process at TSMC (N3E).
