MediaTek has made the Dimensity 6400 official as the successor to last year’s Dimensity 6300 but it only sports a slightly boosted main core. In this short piece, let us take a look at the MediaTek Dimensity 6400, its specs and features, comparisons, and availability details.
MediaTek Dimensity 6400
CPU Architecture
Just like its predecessor, the Dimensity 6400 is fabbed on a 6nm node from TSMC. It has a 2+6 configuration with two ARM Cortex A76 cores running at (up to) 2.5 GHz complemented by six ARM Cortex A55 efficiency cores at 2 GHz. If you look at the spec sheet, it’s only a modest 100MHz jump in prime clock speed over the 6300 so performance is likely going to be very similar. The faster main core might result in slightly improved single-threaded performance but full load capabilities are going to be pretty much the same.
It’s the same as before
Things look even more boring on the GPU end with the exact same Mali-G57 MC2 unit as before with support for up to a 2520 x 1080 120Hz output. This CPU+ GPU combo is not exclusive to the Dimensity 6400 (or even the 6300) though as we have been seeing the same thing since the days of Helio G99 and Dimensity 6100+. It’s somewhat disappointing to see yet another rebrand without any noticeable innovation or improvement.
Other Features
The Image Signal Processor (ISP) also seems pretty much the same with support for up to a 108MP camera, or dual camera setup at 16+16 MP. The chip also includes support for color management but we don’t know much detail in that regard.
In terms of memory, the Dimensity 6400 can be equipped with up to LPDDR4X RAM (2133MHz) and UFS 2.2 storage.
For connectivity, the 6400 is a 5G capable chipset with support for carrier aggregation and Voice over New Radio (VoNR) (basically a 5G version of VoLTE) for improved call quality on 5G networks. There’s support for both NSA and SA 5G with download speeds of up to 3.3 Gbps alongside WiFi 5, Bluetooth 5.2, and various GNSS services (GPS, Galileo, BeiDou, Glonass, QZSS, and NavIC).

MediaTek Dimensity 6400 Availability
We can expect to see the Dimensity 6400 powering lower-end midrange devices in 2025. One of the first phones to launch with this chipset will be the Realme P3x 5G that will be available from the 18th of February.
