MediaTek has launched the Dimensity 9300+, a new chipset designed for flagship smartphones. While a modest upgrade in specifications compared to the Dimensity 9300, the new chip focuses on improved on-device AI processing and broader support for large language models (LLMs).

The chip is compatible with various LLMs, including Google’s Gemini Nano and Meta’s Llama 2 and 3. MediaTek claims this broad LLM compatibility, coupled with its on-device LoRA (Low-Rank Approximation) Fusion technology, will foster a rich ecosystem of generative AI applications.

In fact, the Dimensity 9300+ is claimed to be the industry’s first to achieve high-speed operation for specific LLMs. MediaTek touts a speed of 22 tokens/second for Meta’s Llama 2 7B model. 

Beyond AI, the Dimensity 9300+ promises power efficiency improvements. It reportedly reduces power consumption by 20% for specific gaming scenarios. The chipset also integrates a “star speed engine” to optimize network connectivity and supports dual network concurrency.

Technical Specifications

Built on a 4nm process, the Dimensity 9300+ packs an octa-core CPU with one high-performance Arm Cortex-X4 core clocked at 3.4 GHz, three additional Cortex-X4 cores clocked at 2.85 GHz, and four Cortex-A720 cores running at 2.0 GHz.

The chipset features MediaTek’s new NeuroPilot technology for improved AI processing. The APU 790 AI engine allows for running LLMs with varying parameter sizes, from 1 billion to 33 billion. Notably, it is said to have double the speed of competing solutions for 7 billion parameter LLMs.

For gamers, the Dimensity 9300+ integrates a second-generation hardware raytracing engine with an Arm Immortalis-G720 GPU. 

The chipset also includes MediaTek’s Imagiq 990 ISP for improved camera capabilities and MiraVision 990 for improved visual content processing.

In terms of connectivity, the Dimensity 9300+ boasts a 5G R16 modem with support for Sub-6GHz networks and downlink speeds of up to 7Gbps.

Availability

The Vivo X100S will be the first device to use the Dimensity 9300+. Additionally, the upcoming iQOO Neo9S Pro, slated for release this month, will also be equipped with the new chipset.
