Apple’s 5nm self-developed chip M1 officially debuts, three new Mac products take the lead


In the early morning of the 11th, Apple held its third online product launch conference this year. Apple Silicon’s first self-developed chip, the M1 processor based on the ARM architecture, was officially released. The first batch of MacBook Air, 13-inch with M1 chip. MacBook Pro and Mac Mini also appeared simultaneously.

At WWDC2020 held in June this year, Apple announced the Apple Silicon plan, which is expected to take about two years to migrate the Mac product line to the self-developed processor platform. At that time, Apple CEO Tim Cook stated that “users will be able to purchase computers with Apple Silicon built-in before the end of this year.” Now it is coming as scheduled.

In the early morning of the 11th, Apple held its third online product launch conference this year. Apple Silicon’s first self-developed chip, the M1 processor based on the ARM architecture, was officially released. The first batch of MacBook Air, 13-inch with M1 chip. MacBook Pro and Mac Mini also appeared simultaneously. It can be said that this is a crucial integration node in Apple’s ecology. So far, Apple has completed the entire software and hardware ecological chain, and has super-strong control capabilities that are difficult to replicate by other companies in the industry.

Apple’s M1 chip is manufactured using TSMC’s 5nm process, integrating 16 billion transistors, and because it is based on the ARM architecture and uses SoC design ideas, it is not just a processor. The eight CPU cores are composed of four high-performance large cores and four high-efficiency small cores. The large cores are based on ultra-wide execution architecture. Each core integrates 192KB L1 instruction cache and 128KB L1 data cache. The four cores share 12MB L2 cache; the small core is a wide execution architecture, each core integrates 128KB L1 instruction cache, 64KB L1 data cache, and four cores share 4MB L2 cache. It is also equipped with a three-level cache that all cores can share, but the specific capacity has not been announced.

The GPU specifications are also surprising. It also uses an eight-core design, including 128 execution units, supports up to 24576 concurrent threads, floating-point performance up to 2.6TFlops, texture filling rate of 82 billion per second, and pixel filling rate of 41 billion per second. . Apple said this is the world’s fastest integrated GPU, which can provide up to twice the performance of existing notebook chips at 10W power consumption.

In addition, M1 also integrates 16 core neural engines with a computing power of 11 trillion times per second. The M1 chip adopts a unified memory architecture. The CPU, GPU, neural engine, cache, and DRAM memory are all connected together through the Fabric high-speed bus, which can bring higher bandwidth and lower latency. At the same time, M1 also integrates Thunderbolt/USB4 controller, PCIe 4.0 controller, Secure Enclave security module, machine learning accelerator, high-performance NVMe storage, high-efficiency audio processor, HDR video processor, etc.

Apple said that thanks to the highly integrated design and unified memory architecture, on the optimized macOS Big Sur operating system, M1 can bring a smooth experience comparable to iOS devices, compared with the previous generation MacBook Air equipped with x86 architecture. , The new product replaced with M1 has a speed increase of 3.9 times in high-load video transcoding scenes, a speed increase of 3.6 times in a programming project construction scene, and a 2.3 times performance of x86 processor when exporting Lightroom photos .

Apple said that the MacBook Air with M1 chip can provide 3 times the CPU performance of the previous generation, 5 times the GPU performance of the previous generation, and 9 times the ML deep learning performance of the previous generation. At the same time, the performance is greatly improved while providing super Long battery life, up to 18 hours. In addition, the new M1 version of MacBook Ai also provides Tunderbolt 4 and USB4 connections. In terms of price, the 8+256GB version is 7999 yuan, and the 8+512GB version is 9799 yuan. The specific release date has not yet been determined.

Apple’s 13.3-inch MacBook Pro equipped with M1 processor has also received a huge performance improvement. CPU performance is 2.8 times that of the previous generation, GPU performance is 5 times that of the previous generation, and ML deep learning performance is up to 11 times higher. The battery life has also been increased to 20 hours, an amazing improvement. In terms of price, the 8+256GB version is priced at 9999 yuan, and the 8+512GB version is 11,499 yuan. The specific release date has not yet been determined.

The last is the Mac mini with M1 chip. The appearance design has not changed much, and the weight has been reduced. The back interface part is provincial Thunderbolt 3/USB4. Of course, the most important part is the performance part. Apple said it is equipped with a quad-core x86 compared to the previous generation The processor (i3-8100) Mac mini has a CPU performance up to 3 times and GPU performance up to 6 times. In terms of price, the 8GB+256GB version is 5299 yuan, and the 8GB+512GB version is 6799 yuan. The specific release date has not yet been determined.
