Samsung and TSMC are almost on equal footing when it comes to 5 nm production nodes, yet the Taiwanese foundries are still ahead as far as orders are concerned. Still, the Korean giant intends to pull ahead with the next die shrink, as its 3 nm GAAFET technique is ready to be tested out and could be released in 2021, while TSMC's 3 nm nodes would only come online in 2022.
Bogdan Solca,

One of the highlights of 2019 was the introduction of 7 nm production nodes that helped deliver advanced chips like AMD’s Ryzen 3000-series CPUs along with Navi GPUs and all the latest mobile SoCs including Apple’s A13 Bionic plus Qualcomm’s Snapdragon 855. In turn, 2020 will see the jump to 5 nm nodes, which will fire on all cylinders to fulfill Apple’s orders for the A14 Bionic SoCs that are epxected to power the iPhone 12 models. Still, the 7 nm tech will not be completely pushed aside since Nvidia already booked Samsung’s and TSMC’s foundries for its upcoming Ampere GPUs. Looking into the future, TSMC is planning to introduce 3 nm nodes in 2022, yet Samsung is hoping to pull ahead with a 2021 launch of its advanced 3 nm production technique.

A new report issued by Korean publication Maeil Economy states that Samsung completed research for the 3 nm nodes and prototypes for GAAFET (Gate-All-Around-FET) semiconductors are ready to be tested. This improved technique allows channels to be gated on all four sides, ensuring that the power leakage is kept to a minimum. The advantages over the 5 nm FinFET nodes would be a reduction of the total silicon size by up to 35% and increased performance by 33%, while power consumption is decreased by 50%. APUs and mobile SoCs are expected to benefit the most out of the jump to the GAAFET 3 nm semiconductors, as their performance should get closer to current mid-range desktop CPU + entry level GPU combos.

The report also mentions that Samsung will continue to heavily invest in cutting edge foundries in order to become the world’s largest semiconductor supplier by 2030.

I stepped into the wonderous IT&C world when I was around 7. I was instantly fascinated by computerized graphics, be them from games or 3D applications like 3D Max. I like to keep myself up to date with all the new technologies that get released at an ever increasing rate these days. I'm also an avid SciFi reader, an astrophysics aficionado and, as of late, a crypto geek.
