A few months remain until the Dimensity 9400 is unveiled, and MediaTek has officially announced the Dimensity 9300+, making it the more powerful variant of its 2023 flagship SoC, the Dimensity 9300. The Taiwanese fabless semiconductor manufacturer has improved upon its already impressive chipset, bringing various improvements to the table, which you will find out soon enough when we talk about the detailed specifications.
TSMC’s third-generation 4nm process was used for the Dimensity 9300+, with the silicon designed for taxing on-device AI operations
Like the Dimensity 9300, the Dimensity 9300+ features no efficiency cores, and its Cortex-X4 runs at a slightly higher 3.40GHz than the 3.25GHz clock speeds of MediaTek’s earlier release. The remaining seven Cortex-A720 cores operate at varying frequencies, with the Dimensity 9300+ featuring an 18MB L3 + SLC cache. MediaTek states that it worked closely with TSMC and leveraged the latter’s third-generation 4nm process to mass produce the latest silicon, allowing it to develop a more powerful version that delivers higher performance while exhibiting the same power efficiency.
The Dimensity 9300+ also touts enhanced AI processing over the previous version thanks to MediaTek’s new NeuroPilot Speculative Decode Acceleration technology present in the company’s latest generative AI engine. The highly capable APU 790 AI engine allows the latest chipset to support Large Language Models (LLMs) with 1B, 7B, and 13B parameters, with scalability up to 33B. With NeuroPilot Speculative Decode Acceleration enabled, the Dimensity 9300+ can run LLMs with seven billion parameters at 22 tokens per second, making it twice as fast compared to current solutions.
Coming to the GPU, the Dimensity 9300+ sports a 12-core ARM Immortalis-G720 GPU that implements a second-generation hardware-accelerated ray tracing engine that can deliver enhanced visuals while maintaining a solid 60FPS. MediaTek also boasts that its flagship SoC can play online games at 90FPS in HDR while operating at 20 percent improved efficiency. As for storage, the Dimensity 9300+ is compatible with the UFS 4.0 standard, and for memory, it can support up to the LPDDR5T standard with a maximum bandwidth of 9,600Mbps.
There are also efficiency improvements added to network connectivity, with MediaTek’s HyperEngine’s new Network Observation System (NOS) improving the Wi-Fi and cellular aspects, allowing up to 10 percent in power savings and up to 25 percent cellular data savings. The integrated 5G modem can reach a maximum throughput of 7Gbps, though it is slower than Qualcomm’s latest Snapdragon X70. The Image Signal Processor, or ISP, gets an upgrade too, with the Imagiq 990 supporting 18-bit RAW processing.
The new ISP also has an in-built AI Semantic Analysis Video Engine to support advanced AI videography with a 16-scene segmentation and real-time video capture to reduce noise, increase brightness, and enhance colors. Vivo has already announced that its X100s and X100s Pro will be powered by the Dimensity 9300+, meaning that MediaTek’s partners are wasting little to no time in bringing their new flagships to the market.
