MediaTek: Dimensity 9200 features new Arm cores and ray tracing
8.11.2022 11:11 Nicolas La Rocco
With the Dimensity 9200, MediaTek is the first provider of a flagship SoC that uses Arm's new CPU cores and their new ray-tracing GPU. The chip, manufactured in the second generation TSMC N4, is ahead of Qualcomm, who are planning an announcement for next week, and should appear in the first smartphones by the end of 2022.
The new top model from MediaTek is called Dimensity 9200 and replaces the previous flagships Dimensity 9000 and Dimensity 9000+ (test).
Faster and more economical thanks to TSMC N4P
The biggest innovation of the system-on-a-chip is the use of Arm's latest IP, which the company presented in June of this year. In the Dimensity 9200, a single Cortex-X3 with a maximum of 3.05 GHz works as the prime core, while three Cortex-A715 with up to 2.85 GHz the performance and four Cortex-A510 refresh with up to 1.8 GHz that Form efficiency clusters. ComputerBase's coverage of the Arm Tech Day provides all the details about the new editions.
Compared to US media such as Android Police, MediaTek specifies 10 to 12 percent more raw power for the Dimensity 9200 with 25 percent less consumption compared to the Dimensity 9000. According to a first data sheet (PDF), the chip is manufactured in the "second generation" TSMC N4 alias N4P.
RAM changes to LPDDR5X-8533
For RAM, MediaTek goes from the dual interface that supports LPDDR5-6400 and LPDDR5X-7500 to LPDDR5X-8533, achieving a 14 percent higher bandwidth.
Immortalis-G715 supports hardware ray tracing
At the Tech Day, Arm also presented the Immortalis G715 as the company's first ray tracing GPU. Arm thus ranks behind developers such as Imagination Technologies with the CXT GPU and Samsung and AMD with the Xclipse 920 GPU based on RDNA 2. With the Immortalis-G715, Arm supports expansion stages with 10 to 16 shader cores, each of which has an RTU (Ray Tracing Unit) in its inner core for hardware-accelerated calculations of the bounding volume hierarchy.
More FPS with less consumption
MediaTek itself does not provide any information on the selected GPU configuration in the data sheet, but the note “MC11” can be found on the product page. This configuration was already in previous rumors. According to the previously published benchmarks, which were run with OpenGL ES 3.0 and 3.1 without ray tracing, the Immortalis-G715 MC11 should finish ahead of the current GPUs from Apple and Qualcomm. MediaTek itself names an increase of 32 percent with 41 percent less consumption for the GFXBench Manhattan 3.0.
For image output, MediaTek supports displays with Full HD+ at a maximum of 240 Hz, WQHD at up to 144 Hz and 5K or alternatively 2 × 2.5K at a maximum of 60 Hz - each with a dynamic refresh rate.
Dimensity 9200 is Wi-Fi 7 ready
Other features of the Dimensity 9200 include the image processor (ISP), which brings native support for RGBW sensors, videos in cinema mode, an unblur method and AI-based noise reduction. In terms of connectivity, MediaTek adorns itself with support for the new Wi-Fi 7 standard, which has not yet been fully adopted, as well as Bluetooth 5.3. A new 5G modem covers the sub-6 GHz and mmWave frequency ranges and supports dual SIM dual active.
As part of the "Dimensity Open Resource Architecture" (DORA) program, buyers of the chip can adapt it for market-specific local requirements.
Der Dimensity 9200 nutzt die neuen CPU-Kerne von Arm sowie deren neue Raytracing-GPU und soll Ende 2022 in ersten Smartphones erscheinen.
