MediaTek Dimensity 8400 announced with big performance, efficiency boosts

MediaTek has been making some really interesting pieces of hardware this year, and as 2024 comes to an end, it seems there’s one last chip announcement that the brand wants to get out – the new MediaTek Dimensity 8400. Unlike most chips you know, the new upper mid-range chipset comes with only performance cores, and no efficiency cores.

This means the MediaTek Dimensity 8400 doesn’t have dedicated low-output cores that it can switch to during times of low workloads (something most chipsets do to save power during low workload times). More importantly, the chip does this without basically dying out in record time.

This makes the chip a watered-down Dimensity 9400, which also follows a similar architecture, and works with only performance cores.

How does this work?

The new Dimensity 8400 comes with an octa-core structure with eight Cortex-A725 cores, each of which comes with a 3.25GHz clock speed. But the trick is in the performance metrics of these cores. MediaTek claims the new cores offer 41 per cent improved multi-core performance while offering 44 per cent reduced power consumption.

This is what allows the chip to offer sustained performance, and not lose battery life rapidly while keeping the cores running. This also applies to the new Mali-G720 GPU, which comes with 24 per cent faster performance while being 42 per cent more power efficient.

Other improvements in the chip include the new NPU 880 and the MediaTek Imagiq 1080 ISP for better image processing with HDR. The chip also supports speeds of up to 5.17Gbps and seamless switching between Wi-Fi and 5G networks.

No phones with the new MediaTek Dimensity 8400 chip have been announced so far, but expect quite a few models to sport the chip early next year.
