Huawei Mate 70 RS Teardown: Kirin 9020 Chip Revealed
Since its launch, the Huawei Mate 70 series has received widespread attention for its outstanding performance and unique design. Recently, popular repair blogger @pcbdog conducted a teardown of the Huawei Mate 70 RS, revealing the phone's internal structure and secrets of the Kirin chipset.
During the teardown, the blogger encountered an unprecedented challenge—removing the back cover. The Huawei Mate 70 RS uses a unique Highlight Titanium Xuanwu Frame, which is known for its durability and resistance to drops. The titanium alloy frame is even harder than that of the iPhone, adding considerable difficulty to the teardown.
The blogger had to use multiple tools and considerable effort to make a tiny crack on the back cover. Despite this, the cover remained highly stable, fitting so snugly that it could be held in place without falling off. Eventually, the back cover could only be removed by prying it off, with the expectation that it might be damaged in the process.
Upon opening, it was clear that the adhesive around the back cover maintained a strong bond even when damaged or after being exposed to alcohol, ensuring the phone's robustness and sealing during everyday use.
Opening the back cover revealed the well-arranged internal components of the Huawei Mate 70 RS. The blogger described the orderly and integrated design as "like a carefully crafted work of art."
At the center of the back cover, there is a unique shockproof structure—a specially designed silicone pad that effectively reduces the risk of damage from drops, a feature not found in other smartphones.
The midframe of the device adopts an integrated design without even an antenna slot, maximizing the strength of the body and demonstrating Huawei's powerful communication technology. The metal frame extends throughout the motherboard area and connects closely with it, not only protecting internal components from damage but also enhancing the phone's heat dissipation.
To address potential overheating during prolonged use of large applications or games, Huawei Mate 70 RS includes an advanced cooling system. A large heat sink combined with a heat pipe effectively dissipates heat generated inside, ensuring consistent and stable operation.
The Huawei Mate 70 RS is equipped with a 6.9-inch ultra-high-definition OLED full-screen display, offering an excellent visual experience while being lighter in weight. The hydrogel cooling pad on the back of the screen is larger, and the materials have been significantly upgraded for better thermal conductivity. These improvements contribute to the outstanding performance and cooling of the Mate 70 RS.

The device also features second-generation Kunlun Glass, which is twice as drop-resistant as the first generation. The overall drop resistance of the phone is twenty times better compared to regular glass.
The Mate 70 RS's camera system has also been given significant attention, featuring a multi-camera setup that supports high-definition photos and video recording with multiple shooting modes to meet diverse needs.
The Huawei Mate 70 series features the Kirin 9010 chipset in the Mate 70 model, while the Mate 70 Pro/Pro+/RS debuts with the Kirin 9020 chipset.
The Kirin 9010 chipset, which debuted in the Huawei Pura 70 Pro/Ultra, consists of a 22.3 GHz, 62.18 GHz, and 41.55 GHz CPU core configuration, and uses the Maleoon 910 GPU at a frequency of 750 MHz.
The Kirin 9020 CPU cores are configured as 22.5 GHz, 62.15 GHz, and 41.6 GHz, with a Maleoon 920 GPU at 840 MHz. The benchmark scores of Kirin 9020 are higher compared to Kirin 9010.
The Kirin 9020 chipset has a significantly larger die size compared to the previous generation Kirin 9000S. The chip integrates the CPU, GPU, NPU, modem, and satellite modules, with increased width and thickness, suggesting performance improvements that may exceed a generational leap.
The Kirin 9020 retains the previous generation's 8-core, 12-thread design (software recognizes it as 12 cores), with clock speeds of 22.50 GHz, 62.15 GHz, and 4*1.6 GHz. The GPU is the Maleoon 920, with a frequency of 840 MHz.
From the teardown by the blogger, the Kirin 9010 chip in the Mate 70 also had the marking "2035," similar to the Kirin 9000S and Kirin 9020. A common explanation for "2035" is that since the 35th week of 2020, Huawei's chip orders have not been manufactured by TSMC or other foundries.
