At its Executive Summit in Laguna Beach, California, MediaTek was the first company to announce a processor that could run on 4nm. from TSMC Semiconductor process. New processes enable chip manufacturers to accommodate more computing power in a given space and are usually faster and more energy-efficient.
In the heart of it System on a chip (SoC) there is a powerful heterogeneous CPU cluster that includes Ultra, Super, and Efficiency cores in MediaTek terminology. As the names suggest, each core type has different speed and performance characteristics. The cluster scheduler and the OS thread scheduler work together to automatically distribute the work to the most appropriate core type.

Heterogeneous CPU clusters are not a new concept, but this implementation is exciting to have an ARM Cortex X2 Core as “ultra” core, three Cortex A710 “Super” cores and four Cortex A510 Cores for “efficiency”.
These are all modern CPU core designs that should bring noticeably higher performance and energy efficiency across the board. If anything, I expect more SoC vendors to adopt these new CPU cores, and we’ll have to see if some of them even have custom versions. Right now, MediaTek’s CPU cluster looks really nice.
“MEDIATEK’s CPU CLUSTER LOOKS REALLY GOOD”
The CPU cores access fast LPDDR5 RAM, which offers excellent potential if OEMs opt for the highest type of memory supported. There is a gigantic one 14 MB aggregated CPU cache Memory to stay on the chip as much as possible.

The graphics processor is a ARM Mali G710, a GPU Design released in May 2021. On paper, it should bring 20% more graphics and 35% to GPU-based machine learning apps. Overall, the architecture should achieve an energy efficiency of 20%.
“20% BOOST IN GRAPHICS AND 35% FOR GPU-BASED MACHINE LEARNING APPS”
The Mali G710 also offers Hardware ray tracing (RT), which could be interesting from a developer’s point of view. For consumers, it remains to be seen what kind of ray tracing performance this GPU can achieve (in rays / second) and the quality of the RT noise reduction, two critical points for practical hardware ray tracing.
RT speed determines what game developers do with it and how it ultimately penetrates games. In the short term, legacy rasterization rendering performance remains the most important metric to consider.
This graphics processor supports a 180Hz refresh rate, and maybe that’s an indication of where the displays are going. But this could also be useful for gaming and VR apps, especially since the G710 has a new architecture change to reduce internal latency.
The Dimensity 9000’s image signal processor (ISP) can go nuts 9 billion pixels per second and could support a 320MP camera. The 320 MP number is not to be taken literally, but recording with multiple cameras is “the” real application today.
“THREE-EXPOSURE HDR: ONE OF THE BETTER THINGS FOR CAMERA SOFTWARE”
Recording with all cameras on the phone (rear, ultra wide, zoom, selfie) at the same time is very convenient for content creators. The high-speed ISP enables this with maximum quality. the Noise reduction with three exposures Tech MediaTek talked about is one of the better things that can be done on the software side of photography.

Interestingly, the ISP and the APU (AI processor) Have access to the same storage. Hence, the APU can process images efficiently, which opens the door to more image processing and filtering. This is especially true because the new APU is 4x faster than the previous generation.
“5G NR RELEASE 16: FUTURE-PROOF YOUR PURCHASE”
Dimension 9000 is integrated 5G modem based on the 5G NR 3GPP 16. release Specifications. There are many improvements for networks and carriers to make the transition from 4G to 5G smoother.
5G functions such as updated MIMO protocols and 5G NR without a license in Release 16 increase the speed and capacity of the network and increase the yield a better average network experience for all users. Of course, the network has to be on Release 16, but a compatible device is one way to future proof your purchase.
The Dimensity 9000 supports WLAN 6E and Bluetooth 5.3, the latest enhancement to the popular BT protocol. From the consumer’s point of view, the Bluetooth improvements are mostly in the background. However, the efficiency and optimizations can have a small impact on the battery life.
Overall, the new MediaTek Dimensity is 9000 a real “flagship” platform with which MediaTek will keep up at the very top. It is the culmination of the Dimensity line of products and we look forward to bringing the first devices to market.
Rick Tsai., CEO of MediaTek and its executives attended the introductory event via video (from Taiwan) and gave an excellent overview of the progress made over the past few years. In retrospect, the Dimensity family has climbed every step to the top.
During the Q&A session, some asked what he thought of NVIDIA’s acquisition of ARM. He replied that he believed that “NVIDIA’s technology will continue to improve the capabilities of the CPU and GPU,” and that it was “positive”.
