MediaTek, the largest supplier of chipsets to the smartphone industry, released the Dimensity 9300 last year, and this flagship processor had no small, low-efficiency cores. After an early bump in the road with rumors of overheating, the chip has been a huge success for MediaTek, powering the Vivo X100 series as well as other devices.
The Dimensity 9400 application processor (AP) is expected to have a configuration consisting of one Cortex-X5 super CPU core running up to 3.4 GHz, three Cortex-X4 super CPU cores clocked at up to 2.96 GHz, and four Cortex-A720 efficiency and performance cores running up to 2.27GHz. Again, MediaTek will offer a flagship processor without any low-efficiency cores. It is expected that the chip will deliver a 30% improvement in performance compared to its predecessor.
According to the reliably delicious Digital Chat Station, the first phones powered by the Dimensity 9400 AP will be released in mid-October. This will beat the release of phones powered by the Dimensity 9400 chipset's main rival, the Qualcomm Snapdragon 8 Gen 4. The latter will not be presented until October 21, and if Digital Chat Station is correct, phones powered by the Dimensity 9400 AP will already be on the shelves.
Digital Chat Station's post is consistent with rumors that two phone series expected to be powered by the Dimensity 9400, the Vivo X200 series and the Oppo Find X8 series, could be released before the Xiaomi 15 series. The Xiaomi phones are rumored to be the first equipped with Snapdragon 8 Gen 4 AP.
Digital Chat Station expects the first Snapdragon 8 Gen 4 phones to debut in November or December, giving MediaTek's powerhouse a two-to-six-week lead over Qualcomm's upcoming flagship processor. MediaTek CEO Rick Tsai says he expects the success of the Dimensity 9400 to increase the company's revenue by 50%. The chip will be produced by the leading factory TSMC using their second generation 3nm process node (N3E).
Digital Chat Station's post also mentions a cheaper Dimensity 8400 chipset that will be used in phones in a slightly lower price range than the top-of-the-range models running the Dimensity 9400. The chip could be the largest application processor ever made for a smartphone and is rumored to include 30 billion transistors .
