In the mobile phone market in the first half of this year, MediaTek is a dark horse that has suddenly emerged. Leifeng.com
In the combination of “Fa Ge”, compared with the flagship Dimensity 9000, the “little brother” Dimensity 8100 with better energy efficiency performance is more popular with consumers, becoming the “generation god” in the mid-to-high-end mobile phone market in the first half of the year. U”.
Now, with the release of Dimensity 8200, the sub-flagship “Shen U” is also ushered in an upgrade again.
Compared with the Dimensity 9200 nine-item “first” halo gathering just released last month, the Dimensity 8200 is a bit low-key.
Compared with the previous generation Dimensity 8100, the Dimensity 8200 CPU core number and basic architecture have not changed much. It still uses 4 A78 large cores + 4 A55 small core architectures, but the frequency has been slightly increased. One of the A78 large cores has a main frequency of 3.1GHz, which is 250MHz higher than the main frequency of Dimensity 8100, and has gained nearly 10%. promote.
The GPU follows the highly acclaimed high-efficiency GPU Mali-G610 in the previous generation Dimensity 8100, and supports four-channel LPDDR5
The main frequency is increased to 3.1GHz, an increase of 9%.
The reason why Dimensity 8100 can rise suddenly is mainly because of its excellent energy efficiency performance. The balance between high performance and low power consumption has always been a difficult problem for SoC manufacturers. In the past two years, many SoCs failed to handle the balance between the two when designing, which made the smartphone market once “hot”. It is the excellent energy efficiency performance that made Dimensity 8100 recognized by consumers.
The well-received energy efficiency performance of Dimensity 8100 has also been further upgraded in Dimensity 8200.
Chen Junhong, deputy general manager of MediaTek’s wireless communication division, said: “The Dimensity 8200 continues the high-performance, high-energy-efficiency platform advantages of the Dimensity 8000 series, and at the same time, the performance is further upgraded, which will help the terminal to obtain more stable and smooth high frame rate games. performance, meeting users’ expectations for high performance and long battery life.”
The Dimensity 8200’s process has been upgraded from 5nm to TSMC’s latest 4nm process. Thanks to the process upgrade, the energy efficiency of the Dimensity 8200 has been comprehensively improved, with the CPU energy efficiency increased by 6%, the GPU energy efficiency increased by 8%, and the APU energy efficiency increased by 13%.
Gaming experience is the focus of this Dimensity 8200 upgrade. Dimensity 8200 is equipped with MediaTek HyperEngine 6.0 game engine, which can keep the game full frame for a long time under heavy load conditions.
At the press conference, MediaTek showed the frame rate curve of the open world game suspected of “Yuan Shen” at 60 frames with extremely high quality. Run at full frame. This marks that after the flagship chip has conquered “Yuan Shen”, “Yuan Shen” and other mobile games with high configuration requirements have taken a solid step in the “civilianization” of mobile games.
The energy efficiency performance in the game scene is the highlight of the Dimensity 8200. The Dimensity 8200 optimizes the energy efficiency performance in the game through a number of technologies.
Dimensity 8200 supports CPU multi-threaded intelligent optimization technology (GLT), which can disassemble game tasks into multi-threaded collaborative processing, reduce single-core operating time, reduce load, and effectively reduce load. MediaTek said that after GLT optimization, the average power consumption of CPU execution rendering in the game scene is optimized by about 5%.
The AI variable rate rendering intelligently recognizes the characteristics of the current scene, so as to dynamically adjust the surprise level of the current scene rendering.
For example, in half of the scenes of an FPS game, the surrounding environment will be rendered in detail, and after being hit by a smoke bomb or a flash bomb and the field of view is covered, it will be recognized as being in a non-key scene, reducing the coverage of the covered area Rendering scale, thus reducing power consumption.
In addition, although Dimensity 8200 failed to inherit its own “big brother” hardware ray tracing black technology because it did not use the G715 GPU of Dimensity 9200, Dimensity 8200 still supports mobile ray tracing Vulkan SDK, which can realize software ray tracing. Effect.
Network connectivity is also an important part of the gaming experience. In terms of connection, Dimensity 8200 uses the same generation demodulator as Dimensity 9200, and supports 5G Sub-6GHz full-band network and three-carrier aggregation. In addition, Dimensity 8200 also supports Wi-Fi 6E, which can provide a faster network transmission rate, and also provides a fast channel for multi-app scheduling in game scenarios, and can prioritize the network connection and data packets of game apps and designated apps , up to 85% lower network latency for game apps.
At the same time, Dimensity 8200 is also equipped with Wi-Fi Bluetooth HyperCoex super connection technology. When using Bluetooth headsets or game peripherals, Bluetooth and Wi-Fi can achieve efficient parallel transmission, enabling Wi-Fi to work with Bluetooth headsets and other peripherals at the same time. The delay when used is reduced by up to 60%.
The imaging system has also been enhanced on the Dimensity 8200.
The Dimensity 8200 uses the Imagiq 785 image processor, which increases the maximum supported pixels from 200 million pixels to 320 million pixels, and supports movie mode, which enables real-time focus tracking through simultaneous recording of multiple cameras.
The mediocre night image effect of the previous generation has also been innovated on the Dimensity 8200. Thanks to the AI computing power provided by the high-efficiency APU 580, the Dimensity 8200 can get clearer and less noisy videos when recording in dark light conditions. .
At the press conference, MediaTek announced that the Dimensity 8200 will be launched on today’s IQOO Neo7SE. At the same time, Lu Weibing, general manager of the Redmi brand, also announced on Weibo that the K60E, a new member of the K60 series, will be the first to be equipped with the Dimensity 8200 chip.
