Apple's M1 processors are a big success. When Apple introduced the M1 processors in the MacBook lineup, everyone was impressed by the processor performance and the power efficiency it offered. Just a few days ago, Apple updated its Mac lineup to feature these M1 processors and made it obvious that custom silicon is the way to go in the future. Today, we have information coming from Nikkei Asia, that Apple's next-generation M2 chip has entered mass production and that it could be on the way for as early as July when Apple will reportedly refresh its products. The M2 chip is made inside TSMC's facilities on a 5 nm+ N5P node. While there is no more information coming from the report about the SoC, we can expect it to be a good generational improvement.

TSMC, the world leader in semiconductor manufacturing, has reportedly begun with plans to start volume production of the 4 nm node by the end of this year. According to the sources over at DigiTimes, Taiwan's leading semiconductor manufacturer could be on the verge of starting volume production of an even smaller node. The new 4 nm node is internally referred to as a part of the N5 node generation. The N5 generation covers N5 (regular 5 nm), N5P (5 nm+), and N4 process that is expected to debut soon. And perhaps the most interesting thing is that the 4 nm process will be in high-volume production in Q4, with Apple expected to be one of the major consumers of the N5 node family.

DigiTimes reports that Apple will use the N5P node for the upcoming Apple A15 SoCs for next-generation iPhones, while the more advanced N4 node will find itself as a base of the new Macs equipped with custom Apple Silicon SoCs. To find out more, we have to wait for the official product launches and see just how much improvement new nodes bring.

TSMC on Monday kicked off a virtual tech symposium, where it announced its new 12 nm N12e node for IoT edge devices, announced the new 3DFabric Technology, and detailed progress on its upcoming 5 nm N5 and 3 nm N3 silicon fabrication nodes. The company maintains that the N5 (5 nm) node offers the benefits of a full node uplift over its current-gen N7 (7 nm), which recently clocked over 1 billion chips shipped. The N5 node incorporates EUV lithography more extensively than N6/N7+, and in comparison to N7 offers 30% better power at the same performance, 15% more performance at the same power, and an 80% increase in logic density. The company has commenced high-volume manufacturing on this node.

2021 will see the introduction and ramp-up of the N5P node, an enhancement of the 5 nm N5 node, offering a 10% improvement in power at the same performance, or 5% increase in performance at the same power. A nodelet of the N5 family of nodes, called N4, could see risk production in Q4 2021. The N4 node is advertised as "4 nm," although the company didn't get into its iso-power/iso-performance specifics over the N5 node. The next major node for TSMC will be the 3 nm N3 node, with massive 25%-30% improvement in power at the same performance, or 10%-15% improvement in performance at same power, compared to N5. It also offers a 70% logic density gain over N5. 3DFabric technology is a new umbrella term for TSMC's CoWoS (chip on wafer on substrate), CoW (chip on wafer), and WoW (wafer on wafer) 3-D packaging innovations, with which it plans to offer packaging innovations that compete with Intel's various new 3D chip packaging technologies on the anvil.
