MediaTek Dimensity 8300 4nm SoC official; Dimensity 8300-Ultra to power Redmi K70E

MediaTek just announced Dimensity 8300, the company’s latest 8000 series SoC for premium 5G smartphones, as the successor to Dimensity 8200. It uses second-generation TSMC’s 4nm process tech.


The Octa-Core processor has 4 x Cortex-A715 performance cores with a maximum frequency of 3.35GHz and 4 x Cortex-A510 energy efficiency cores with a maximum frequency of 2.2GHz. The performance is improved by 20% compared with the previous generation, and the power consumption is reduced by 30%, said the company.

The 6-core Mali-G615 GPU promises 60% improved peak performance, and the power consumption is reduced by 55% compared to the previous generation, says the company.


The Dimensity 8300 is the first in its class to support full generative AI, thanks to APU 780 AI processor integrated into the chipset. This enables the Dimensity 8300 to provide support to developers to build innovative applications that leverage large language models (LLMs) up to 10B, as well as stable diffusion.

The APU 780 features the same architecture as the flagship Dimensity 9300 SoC, resulting in 2x improvement in INT and FP16 computation and a 3.3x boost in AI performance over the Dimensity 8200.


It has MediaTek’s 14-bit HDR-ISP Imagiq 980. It promises sharper, clearer videos at 4K60 HDR, and record for longer thanks to the Dimensity 8300’s extremely power efficient design.

The HyperEngine adaptive game technology offers advanced power savings enhancements. The chip intelligently adapts to computing demands and monitors device temperature, keeping devices cool while optimizing gameplay, so users can enjoy full FPS, low lag, and seamless rendering, according to the company.


The Dimensity 8300 supports ultra-fast speeds with a built-in 3GPP Release-16 standard 5G modem. The modem supports 3CC carrier aggregation, with up to 5.17Gbps downlink speeds.

MediaTek said that the Dimensity 8300 SoC will power 5G devices launching in the global market before the end of 2023.

Redmi K70E with Dimensity 8300-Ultra

Xiaomi Civi3 and Redmi Note 12T Pro were introduced earlier this year with Dimensity 8200-Ultra, a custom chip for Xiaomi.

Today, Xiaomi has confirmed that Redmi K70E that will launch later this month will be powered by the Dimensity 8300-Ultra SoC, a custom chip for Xiaomi. It also revealed that the phone has over 1.52 million points on AnTuTu 10.

Dr. Yenchi Lee, Deputy General Manager of MediaTek’s Wireless Communications Business Unit, said:

With MediaTek’s optimized Dimensity 8000 series, consumers don’t have to pick and choose between accessibility and premier experiences like flagship-grade memory or accelerated AI capabilities—they can have it all. The Dimensity 8300 unlocks new possibilities for the premium smartphone segment, offering users in-hand AI, hyper-realistic entertainment opportunities, and seamless connectivity without sacrificing efficiency.
