'ZDNet Recommends': What exactly does it mean?
ZDNet's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNet nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNet's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via this form.
Apple has been designing its own ARM-based silicon since 2020 when it moved away from Intel chips. As David Gewirtz wrote for ZDNet earlier this year, "By removing its reliance on Intel's innovation teams, Apple can engineer to its specific priorities. The result is apparent." For almost all activities, Apple's Silicon-based Macs far surpass their equivalent Intel-based Macs in terms of performance, battery life and heat.
The system-on-a-chip (SoC) design of M2 is built using second-generation 5-nanometer technology. It consists of 20 billion transistors, a 25% increase over the M1.
Compared to the M1, the M2 delivers 18% greater multi-core CPU performance. M2's CPU yields nearly 2x faster performance compared to the latest PC laptop chip at the same power level, according to Apple. Underscoring the power-efficient performance of its own silicon, Apple said the M2 delivers nearly 90% of the peak performance of the latest 12-core PC laptop chip while using just a quarter of the power.
The M2 also features Apple's next-generation GPU, which now has up to 10 cores. Combined with a larger cache and higher memory bandwidth, the M2 GPU delivers a big boost in graphics performance. It delivers up to 25% higher graphics performance at the same power level as M1 and up to 35% higher performance at its max.
Compared to the integrated graphics in the latest PC laptop chip, the M2's GPU delivers 2.3x faster performance at the same power level. Additionally, M2 delivers the peak performance of the PC chip using just one-fifth of the power.
M2 also features Apple's latest custom SoC technologies, including its next-generation Secure Enclave and neural engine.
It also features Apple's next-generation media engine, including a higher bandwidth video decoder that supports 8K H.264 and HEVC video.
