TSMC has confirmed its 3nm production node is on track for full mass production in the second half of 2022, according to Chinese tech site ItHome (in Chinese). TSMC reckons its 3nm node will pack in somewhere north of 250 million transistors per square millimetre of silicon, making it at least two and half times more dense than Intel's latest 10nm node. In theory, TSMC's 3nm tech could enable a GPU three times more complex than AMD's new Radeon RX 6000 Series chips
TSMC, of course, makes all of AMD's high performance Ryzen CPUs and Radeon GPUs. Until recently, it also produced Nvidia's top graphics chips, too. Advances like TSMC 3nm tech matter because they allow for more complex, faster computer chips. Like, you know, CPUs and GPUs.
But just think about it. AMD's Navi 21 GPU, the chip inside the Radeon 6800 and 6900 Series boards, clocks in just under 27 billion transistors using 7nm. So a 3nm GPU of the same size could pack around 80 billion transistors if they really pushed it.
