After M1, M1 Pro, M1 Max and M1 Ultra, Apple finally introduced M2, the second generation of Apple Silicon’s own processors.
M2 is manufactured using an enhanced second-generation 5nm process and integrates over 20 billion transistors, an increase of 25% over M1.
Integrated up to 24GB LPDDR5 unified memory, 128-bit width, bandwidth over 100GB/s, 50% more than M1.
Eight new architecture CPU cores, four large and four small, of which four performance cores are ultra-wide execution architectures, each with 192KB instruction cache, 128KB data cache, and 16MB shared cache (increased by one-third).
Four energy efficient cores, still wide execution architecture, 128KB instruction cache for each core, 64KB data cache, shared 4MB cache, unchanged.
Compared with M1, the performance is improved by 18% under the same power consumption. Compared with the 10-core x86 notebook processor, the performance under the same power consumption (15W) is 90% better; Compared to a 12-core laptop processor, 25% power consumption translates into 87% performance.
10 GPU cores, two more than M1, with 25% performance improvement under the same power consumption and 35% performance improvement under the highest power consumption; Compared to the 10 core notebook processors, the same power consumption (15W) can achieve 2.3 times performance, only 35% of the power consumption can match the highest performance.
Of course, apple’s performance comparisons are pretty psychedelic, so just take a look, don’t take it too seriously.
Integrated with the new security isolation area and neural engine, it can perform 15.8 trillion operations per second, 40% more than M1.
The integrated new-generation media processing engine supports 8K H.264/H.265 videos, can play multiple 4K/8K videos at the same time, supports ProRes video codec, and supports external 6K display.
