Apple M2 chip officially released

Apple officially released the M2 chip, the successor of the M1 chip.

Apple's new M2 uses the second-generation 5nm process, with 20 billion transistors, 25% more than the M1, 18% faster CPU and 35% faster GPU.

According to reports, Apple's new M2 uses an 8-core CPU + 10-core GPU . According to Apple, the M2 has 1.9 times the performance of "the latest 10-core PC laptop chips."

In other respects, Apple's new M2 supports unified memory with a bandwidth of up to 100GB/s and a capacity of up to 24GB, which is 50% more bandwidth than the M1.

The M2 also features a next-generation Neural Engine and a media engine that supports 8K H.264 and HEVC video, and will be able to play multiple 4K and 8K video streams simultaneously.

Apple's official interpretation:

"The M2 chip ushered in the second generation of the M-series chip and enhanced the outstanding capabilities of the M1 chip," said Johny Srouji, Apple's senior vice president of hardware technology. The processor and neural network engine have been significantly faster. Combined with higher memory bandwidth and new ProRes codec acceleration, the M2 chip continues our incredible pace of innovation for the Mac.”

The SoC chip of the M2 chip adopts an enhanced second-generation 5-nanometer process, which integrates a total of 20 billion transistors, an increase of 25% compared to the M1 chip. The new transistors improve all aspects of the chip's performance, including a memory controller that achieves a unified memory bandwidth of 100GB/s, which is as much as 50% higher than the M1 chip. And thanks to high-speed unified memory of up to 24GB, the M2 chip can handle larger and more complex tasks.

The central processing unit of the new chip uses a faster high-performance core and a larger cache, and the high-efficiency core has also been greatly increased, further improving performance. Therefore, the multi-threaded processing performance of the M2 chip is 18% higher than that of the M1 chip, and tasks that require a lot of CPU can be easily completed with very low power consumption, such as creating music with rich sound effects, or applying complex functions to photos. filter. Compared with the latest 10-core PC notebook chips, the central processing unit of the M2 chip can achieve nearly twice the performance at the same power consumption level. In addition, the M2 chip consumes only 1/4 the power of the aforementioned PC notebook chips at peak performance. Compared with the latest 12-core PC notebook chips, the M2 chip can reach nearly 90% of its peak level performance with only 1/4 the power consumption of the former, and the former must greatly increase the power consumption to achieve the performance improvement, resulting in The entire system is larger, generates more heat, makes more noise, and has shorter battery life.

The M2 chip also uses Apple's next-generation graphics processor with up to 10 cores, two more than the M1 chip. Thanks to the larger cache and higher memory bandwidth, the graphics performance of the 10-core graphics processor has been greatly improved, and the graphics performance at the same power consumption level is up to 25% higher than that of the M1 chip. At the highest power consumption level Its performance is up to 35% higher than that of the M1 chip. Compared to the integrated graphics processor of the latest PC notebook chips, the graphics processor of the M2 chip runs 2.3 times faster at the same power consumption level and requires only 1/5 the power consumption of the former to reach its peak level performance. The higher power consumption ratio of the M2 chip allows the system to achieve exceptional battery life while maintaining extremely low heat and noise, even when playing complex games or editing large RAW images.

The M2 chip brings Apple's latest custom technology to the Mac, unlocking new features, improving security, and more:

  • The neural network engine can perform up to 15.8 trillion operations per second, more than 40% higher than the M1 chip.
  • The media engine integrates a higher bandwidth video decoder, supporting 8K H.264 and HEVC video.
  • Apple's powerful ProRes video engine supports simultaneous playback of multiple 4K or 8K video streams.
  • Apple's latest Safe Enclave provides users with industry-leading security.
  • The latest Image Signal Processors (ISPs) further reduce image noise.
