MediaTek has introduced Dimensity 7400, another 7000 series chipset, as the successor to last year’s Dimensity 7300. Similar to last year, there is also Dimensity 7400X designed for flip-style foldable devices with support for dual displays.
Both these octa-core SoCs pack 4X Arm Cortex-A78 cores at up to 2.6 GHz paired with 4X Arm Cortex-A55 cores. There is a slight increase in clock speed for the performance cores, otherwise the specifications remain almost the same.
With TSMC’s 4nm process node, these use between 14% to 36% less power when gaming compared to competitive chipsets, said the company. These still feature MediaTek’s NPU 6.0, but these promise a 15% upgrade in performance over the Dimensity 7300.
These retain Imagiq 950 ISP, 5G R16 modem with 3CC carrier aggregation (3CC-CA), Tri-band Wi-Fi 6E support.

Dimensity 6400
There is also Dimensity 6400 with octa-core CPU with 2X Arm Cortex-A76 cores operating up to 2.5GHz and 6X Arm Cortex-A55 cores up to 2.0GHz, a slight increase in clock speed for the performance cores compared to 6300. It is still based on TSMC’s 6nm process node, and the company says that it uses 19% less power when gaming compared to competitive chipsets.
There is MediaTek Bluetooth Wi-Fi HyperCoex Technology, which reduces gaming latency by up to 90% for a smoother gaming experience, according to the company.
It also offers support for billion-color displays with real 10-bit images and videos for vivid visuals and supports True Color Accuracy for improved color correction, generating more accurate and lifelike visuals.
