MediaTek used to focus on cheap, entry-level chips, but it’s been slowly gaining ground on Qualcomm in the flagship space over the past few years. Now MediaTek has announced the Dimension 9200, which doesn’t compromise on power or connectivity. It debuts a new GPU, a new ARM core, and even a new Wi-Fi standard — Wi-Fi 7 to be precise. You probably won’t come across a Wi-Fi 7 network for a while, but the Dimensity 9200 is ready for the future.

While the Dimension 9200 has a lot of new technology, there’s nothing revolutionary about the basic design. It is a 4nm octa-core ARM system-on-a-chip (SoC) with three CPU islands. There is a group of four low-power Cortex-A510 cores at 1.8GHz, along with a set of three high-power Cortex-A715 cores at 2.85GHz. The final piece is a single Cortex-X3 CPU, which is faster than all other CPU cores and clocks at 3GHz. The Dimensity 920 is the first chip to feature X3, Arm Holdings’ latest Cortex-X custom design.

This chip is the first to have Arm’s Immortalis-G715 GPU. This component supports many high-end gaming features that are rare in mobile chipsets, including variable rate shading, ray tracing, and 5K resolution output. In fact, the Dimensity 9200 can handle two 5K displays, although the refresh rate is limited to 60Hz. At 1440p, you can get up to 144Hz and 1080p devices will be able to refresh at 240Hz. Arm says the new GPU features an improved execution engine that’s 15 percent faster than its last, making Immortalis Arm’s fastest reference GPU to date.

AI processing is all the rage these days, and the Dimension 9200 has you covered here too. This SoC features MediaTek’s sixth-generation APU 690 with a 25 percent improvement in the ETHZ5.0 AI benchmark. The 9200 has an iMagic 890 ISP with RGBW camera sensor support and 30 percent lower power consumption than the last-gen chip.

MediaTek has been slow to adopt some of the more advanced connectivity features that US carriers have demanded, but the Dimension has hit all the high points. As mentioned earlier, it has Wi-Fi 7 support – the first mobile chipset to offer it. When Wi-Fi 7 networks actually start appearing, devices with the Dimension 9200 will be able to transfer data at up to 6.5Gbps. It has both sub-6 and millimeter wave 5G, the latter of which can reach gigabit speeds if you’re close to the transmitter — even last year’s Dimension 9000 didn’t have that. This spectrum is currently only common in the US, but carriers like Verizon often require manufacturers to support it.

MediaTek Dimensity 9200 is already available to OEMs to build phones. Our first Dimension 9200-based devices should launch in late 2022.
