Manufacturing course of and transistors

Just like the A14 Bionic, the ‌M1‌ chip is constructed utilizing TSMC’s first technology 5nm manufacturing course of. However, the M2‌ makes use of TSMC’s second technology 5nm course of just like the A15 Bionic chip. The M2 provides 4 billion further transistors for a complete of 20 billion – 25 p.c greater than the M1. An improved 5nm manufacturing course of is on the coronary heart of lots of the M2‌’s efficiency and effectivity enhancements.

CPU

The ‌M1‌ and ‌M2‌ have 4 high-performance cores and 4 energy-saving cores, however whereas the ‌M1‌ options the “Firestorm” and “Icestorm” cores of the A14 Bionic chip, the ‌M2‌ gives the “Avalanche” and “Blizzard” of the A15 Bionic chip. . In accordance with Apple, this ends in 18 p.c extra multithreaded efficiency than the M1.

CPU performance m1 vs m2


in Early Geekbench Benchmarks, the M2‌, which runs at 3.49 GHz in comparison with 3.2 GHz for the M1‌‌, had a single-core rating of 1,919, which is roughly 12 p.c quicker than the 1,707 single-core rating of the 13-inch MacBook Professional M1. The M2‌ has a multi-core rating of 8,928, a rise of about 20 p.c from the 7419 rating for the M1‌ mannequin. That is totally consistent with Apple’s declare that the M2‌ chip is as much as 18 p.c quicker than the M1 chip.

Each chips have high-performance cores with 192KB of L1 instruction cache and 128KB of L1 knowledge cache. Power-saving cores include a 128KB L1 instruction cache, a 64KB L1 knowledge cache, and a 4MB L2 shared cache. The one distinction right here is that the shared L2 cache is bigger on the M2‌ chip — 16MB as an alternative of 12MB on the M1‌.

GPU

The ‌M2‌ options two extra GPU cores on the ‌M1‌, which leads to a average improve in graphics efficiency. Apple says the M2‌ has as much as 25 p.c greater graphics efficiency than the M1 on the similar energy degree, and as much as 35 p.c higher efficiency at its most energy. Within the early Geekbench Steel benchmarks, the ‌M2‌ chip scored 30627, a marked enchancment over the 21,001 rating obtained by the ‌M1‌.

GPU Performance M1 vs M2

media engine

Each ‌M1‌ and ‌M2‌ have devoted video encoding and decoding engines for hardware-enhanced H.264 and HEVC, however ‌M2‌ video engines are additionally able to ProRes and ProRes RAW acceleration to allow playback of a number of streams of 4K and 8K video. As well as, the ‌M2‌ media engine features a greater bandwidth video decoder, supporting 8K H.264 video and HEVC.

consolidated reminiscence

The ‌M1‌ and ‌M2‌ are available in configurations with both 8GB or 16GB of unified reminiscence, however the ‌M2‌ provides an extra 24GB first-class configuration. The ‌M2‌ reminiscence controller can even present 100GB/s of mixed reminiscence bandwidth, a major enchancment over the M1‌’s 68.25GB/s reminiscence bandwidth.

Different enhancements

The ‌M2‌ options enhancements to a number of customized silicon applied sciences from Apple. For instance, the Neural Engine can course of as much as 15.8 trillion operations per second — greater than 40% greater than the ‌M1‌. The ‌M2‌ additionally has Apple’s newest Secure Zone and a brand new Picture Sign Processor (ISP) for higher picture noise discount.

final ideas

Total, the ‌M2‌ chip gives average enhancements over the ‌M1‌, even when most M1 customers aren’t more likely to discover vital enhancements when upgrading to ‌M2‌. The developments within the M2‌ are typically noteworthy, if not transformative, and the chip is bound to offer a extra trendy expertise with Apple’s low-spec silicon {hardware} — particularly people who come from an Intel-based machine.

Whereas the ‌M2‌ gives enhancements throughout the board because of an improved 5nm course of, up to date cores, and extra GPU cores, the main upgrades come for customers who must work with video, in addition to these with memory-intensive workflows. The high-bandwidth ‌M2‌ video decoder and devoted engine for ProRes and ProRes RAW video present helpful enhancements for video editors, whereas a unified 24GB reminiscence layer and 100GB/s reminiscence bandwidth enormously improve the power of M2‌ {hardware} to deal with Purposes that devour a number of reminiscence and intensive multitasking.
