Huawei Memory Expansion Technology
On the afternoon of October 30, Huawei’s annual flagship release ceremony was held as scheduled, and its Mate 40 series was officially released in China. Yu Chengdong said Huawei Mate 40 series is equipped with a new memory expansion technology, physical memory 8GB is equal to the expanded equivalent memory 10GB, physical memory 12GB is equal to the expanded equivalent memory 14GB.
The memory capacity of Android phones are on 16GB, Apple iPhone 12 is still up to 6GB, but many people still feel that Android is stuck. Just at the Mate40 conference, Huawei announced a new memory expansion technology, 12GB of memory seconds into 14GB. Android stuck or not, memory is the key, frequent cleaning of the background will again lead to a reduction in resident apps, so on the Mate40 series of phones, Huawei introduced a new memory expansion technology, which can make the equivalent capacity of memory a quarter larger, 8GB equivalent 10GB, 12GB equivalent 14GB.
According to Huawei, this memory expansion technology uses dynamic packet compression, super memory flash fusion, and other technologies, but the specific principles were not announced, speculation is that some of the capacity of the flash memory as virtual memory. After supporting this technology, the Mate 40 even 8GB of memory, the number of background resident apps from the Mate ’30s 11 to 16.6, an increase of 50%, can accommodate more apps at the same time, without having to kill the background frequently.
In terms of other specifications, the three new models all use a dual-curved dug-out screen form, the Mate 40 is a single dug-out, not much curvature, Pro/Pro+ version is a double dug-out, curvature and close to the waterfall screen; the back continues the Mate axis of symmetrical design, the camera for the “starring” layout, the sense of identity.
The Mate 40 is available in secret silver, glazed white, glossy black, green, and yellow; the Mate 40 Pro is available in glossy black, glazed white, secret silver, autumn poplar (plain leather), and summer poplar (plain leather); the Mate 40 Pro+ is available in ceramic black and ceramic white.
The screen differences are that the Mate 40 has a 6.5-inch OLED screen with 2376×1080 resolution and supports 90Hz refresh rate + 240Hz touch sample rate, while the Pro and Pro+ have a 6.76-inch 88-degree Super Curved Surround screen with 2772×1344 resolution and supports 90Hz high refresh rate + 240Hz touch sample rate, DCI-P3 Color gamut.
The core configuration is also different, where the Mate 40 Standard Edition is equipped with a Kirin 9000E chip, compared to the Kirin 9000 cut two GPU cores, dual-core NPU; Pro/Pro+/RS Porsche Design is all equipped with 5nm process Kirin 9000 chip. The Kirin 9000 is the world’s first 5nm 5G SoC with 15.3 billion transistors, 30 percent more than the A14 Bionic, and the CPU part consists of one 3.13GHz A77 large core + three 2.54GHz A77 medium cores + four 2.04GHz A55 small cores, surpassing the Snapdragon 865 Plus’ 3.1GHz main frequency.
At the same time, the Kirin 9000 integrates a 24-core Mali-G78 GPU for the first time in the industry, claiming a 60 percent performance boost over the Kirin 990; the AI side integrates two large-core and one micro-core NPU for a 100 percent performance boost, as well as a quad-core ISP. Officials say the Kirin 9000 offers a 10 percent performance boost over the Snapdragon 865 Plus, with 140 percent more NPU and 52 percent more GPU, while the Snapdragon 865 Plus has 25 percent more CPU, 150 percent more NPU, and 50 percent more GPU for energy efficiency.
The camera remains one of the main highlights of the series, with a 50 megapixel’s large sensor (full pixel octa-core focus) standard across the range, with the Mate 40 backed by a 50 megapixel’s RYYB super-sensitive camera (23mm, f/1.9) + 16 megapixel’s ultra-wide-angle camera (17mm, f/2.2) + 8 megapixel’s telephoto camera (85mm, f/2.4, OIS optics) (anti-shake), supports 5x optical zoom range.
The Mate 40 Pro has a 50 megapixel’s RYYB (23mm, f/1.9 aperture) + 20 megapixel’s super-wide-angle cinema camera (18mm, f/1.8 aperture) + 12 megapixel’s telephoto camera (125mm, f/3.4 aperture, OIS Optical Image Stabilization) on the rear with support for 7x optical zoom range.
The Mate 40 Pro+ comes with a free-form camera to reduce deformation at the edges of the image, and a rear-mounted 50 megapixel’s super-sensitive camera (f/1.9 aperture, OIS optical image stabilization support) + 20 megapixel’s cinema camera (super wide-angle, f/2.4 aperture) + 12 megapixel’s telephoto camera (f/2.4 aperture, OIS optical image stabilization support) + 8 megapixel’s super-zoom. Camera (10x optical zoom, f4.4 aperture, OIS optical stabilization support) + 3D Deep Camera with 3x/10x optical zoom, 20x hybrid zoom, and 100x digital zoom support.
All three new models have a 13-million super-sensitive camera (wide-angle, f/2.4 aperture) on the front, but the Pro and Pro+ add a 3D depth camera with support for AI Air control, 3D face recognition, slow-motion selfies, distortion correction, and 4K video recording.
In terms of charging, the Mate 40 supports 40W wired fast charging and 40W wireless fast charging with a battery capacity of 4200mAh, while the Pro and Pro Plus versions support 66W wired super-fast charging and 50W wireless super-fast charging with a battery capacity of 4400mAh.
