MediaTek calls the C10 Max the “flagship of the lineup,” though we don’t have full specs on the chip, and not so much as a name for the other chips in the lineup. MediaTek is launching the CPU on the same day Googlebooks go on sale (September 21), and the company says it will power an upcoming Googlebook device. MediaTek hasn’t explicitly said that the chip is exclusive to Googlebook devices, though that seems likely given the company’s previous work with Google on Chromebooks.
The C10 Max is an “all big core” CPU, according to MediaTek, but not all eight cores are equal. MediaTek is using three different core types: one Cortex-X925 core, three Cortex-X4 cores, and four Cortex-A720 cores. The Cortex-X925 is the successor to the Cortex-X4, with higher clock speeds, a larger 10-wide decode, and larger L2 cache. The Cortex-A720 fits in a different range, though it was succeeded in 2024 by the Cortex-A725. This core split is identical to what MediaTek has used in its Dimensity 9400, 9400+, and 9500s mobile chips (though, presumably, the C10 Max will be afforded a larger power budget and higher boost clocks).
Perhaps more pressing, it’s identical to the core split in the Kompanio Ultra 910, MediaTek’s previous flagship in this category. The C10 Max features the same GPU and NPU, as well: the Arm Immortalis-G925 MC11 for the GPU and MediaTek NPU 890. The C10 Max also comes with the same 12MB of L3 and 10MB of system-level cache. The biggest difference, at least based on the specs MediaTek has shared, is memory speed. Both use LPDDR5X, but the C10 Max climbs up to 9,600MT/s from 8,533MT/s on the Kompanio Ultra 910.
On performance, MediaTek has two rather vague claims, which you can see in the slide below. It claims the C10 Max has up to 15% faster multi-threaded performance and 50% lower power in single-threaded workloads, though without any mention of performance, compared to the Snapdragon X Elite X1E-84-100. That chip is the second from the top of Qualcomm’s last-gen X Elite stack, sporting 12 cores (8+4) and a 4.2 GHz boost clock. MediaTek says it used Geekbench 6.5 and ran the multi-threaded tests at iso-power, that being 12W (the X1E has a base TDP of 35W, and MediaTek didn’t clarify what power usage it was referencing).
