Chip Buyer's Guide M1 Vs. M2: How much better is M2 really? Listen to this article

This month, Apple introduced the M2 chip, a second-generation custom silicon chip for Macs. After the M1 chip revolutionized the Mac starting in November 2020, how much better is the M2 really?

M1 vs M2
Apple says the m2 chip takes the M1’s performance per watt even further with an 18% faster CPU, 35% more powerful GPU, and 40% faster Neural Engine. There are other big improvements as well, such as more memory bandwidth and support for up to 24GB of integrated memory.

As Apple’s second major iteration of silicon, it may not be clear how significant the improvements in ‌M2′ are, especially since it sticks to a 5nm manufacturing process, contrary to some rumors that suggest it’s an improvement in performance. Big leap and potential. In store. The 13-inch MacBook Pro and the redesigned MacBook Air debut the ‌M2‌ chip, so how much better the ‌M2‌ is than its predecessor can be an important consideration when shopping for a new Mac. difference between the two chips.

  • 8 GB, 16 GB, or 24 GB integrated memory support
  • 100 Gb/s memory bandwidth
  • Neural Engine 40 percent faster
  • Media Engine for Hardware Accelerated H.264, HEVC, ProRes and ProRes RAW
  • High Bandwidth Video Decoding Engine
  • video encoding engine
  • ProRes encoding and decoding engine
  • “New” Image Signal Processor (ISP)

Manufacturing process and transistors

Like the A14 Bionic, the ‌M1 chip is fabricated using TSMC’s first-generation 5nm manufacturing process. On the other hand, the m2 uses TSMC’s second generation 5nm process as the A15 Bionic chip. The M2 adds an additional four billion transistors for a total of 20 billion, which is 25 percent more than the M1. An improved 5nm manufacturing process is at the heart of many of the M2’s performance and efficiency improvements.

cpu

The M1 and M2 have four high-performance and four low-power cores, but while the M1 has “Firestorm” and “Icestorm” cores from the A14 Bionic chip, the M2A15 offers “Avalanche” and “Blizzard” from the Bionic chip . .. According to Apple, this results in 18 percent higher multithreaded performance compared to the M1.

शुरुआती गीकबेंच बेंचमार्क में, ‌M1 के लिए 3.2 GHz की तुलना में 3.49 GHz पर चलने वाले ‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌-1707 का 13-इंच मैकबुक ‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌-1‌‌‌‌‌‌‌‌‌‌‌‌‌‌-1]‌‌‌‌‌‌‌‌‌‌‌‌‌‌–कोर]स्कोर 1919, का एक-कोर स्कोर 1919 था। , Pro. The M2 achieved a multi-core score of 8,928, which is 20% higher than the M1’s score of 7,419. This is in line with Apple’s claim that the M2 chip is up to 18 percent faster than the M1.

Both chips have high-performance cores with 192 KB L1 instruction cache and 128 KB L1 data cache. The energy efficient core has 128 KB L1 instruction cache, 64 KB L1 data cache and 4 MB shared L2 cache. The only difference here is that the shared L2 cache is larger on the M2 chip: 16MB instead of 12MB on the M1.

GPU

The M2 has two more GPU cores than the M1, resulting in a slight increase in graphics performance. Apple says that the M2 has 25% better graphics performance than the M1 at the same power level, and up to 35% better performance at its maximum power. In the initial Geekbench Metal benchmark, the m2 chip scored 30,627, which is a marked improvement from the m1 score of 21,001.

M1 vs M2 GPU Performance

media engine

Both the M1 and ‌M2‌ have dedicated hardware-accelerated H.264 and HEVC video encoding and decoding engines, but the 2M2 video engine can also accelerate ProRes and ProRes RAW to enable playback of multiple 4K video streams and 8K. Additionally, the m2’s media engine includes a high-bandwidth video decoder, supporting 8K H.264 and HEVC video.

integrated memory

The m1 and m2 come in configurations with either 8GB or 16GB of integrated memory, but the m2 adds an additional top-tier 24GB configuration. The M2’s memory controller can offer an integrated memory bandwidth of 100 Gb/s, which is a substantial improvement over the M1’s 68.25 Gb/s memory bandwidth.

Other improvements

The M2 features improvements to many of Apple’s custom silicon technologies. For example, the Neural Engine can process 15.8 trillion operations per second, which is 40 percent more than the M1. The m2 also includes Apple’s latest Secure Enclave and a new Image Signal Processor (ISP) for better image noise reduction.

final thoughts

Overall, the M2 chip offers moderate improvements over the M1, even though most M1 users are unlikely to notice significant improvements when upgrading to the M2. The progress of the m2 is generally worth it, if not transformational, and the chip is sure to provide a more up-to-date experience with lower-spec Apple silicon machines, especially those coming from an Intel-based machine.

While the m2 delivers improvements across the board thanks to its improved 5nm process, updated cores, and additional GPU cores, the major updates come for users who need to work with video, as well as those with workflows that They make heavy use of memory. The m2’s high-bandwidth video decoder and dedicated engine for ProRes and ProRes RAW provide significant improvements for video editors, while the 24GB of integrated memory tier and 100GB/s of memory bandwidth enhance the ability of ‌M2 Machines‌ to handle memory-intensive applications. Increases significantly. and intense multitasking.
