TSMC will produce 5nm in the first half of this year, this year’s production capacity will be almost by Apple A14 and Huawei’s Kirin 1020 processor package, other manufacturers to line up next year, AMD’s Zen4 is running for 2022. According to WikiChips’ analysis, TSMC’s 5nm gate spacing is 48nm, the metal spacing is 30nm, the fin spacing is 25-26nm, and the unit height is about 180nm, so the tSMc’s 5nm transistor density will be 171.3 million per square millimeter.
That’s up 88 percent from the 91.2 million square millimeters per square millimeter of the first generation, compared with 84 percent for TSMC.
In addition to the surge in transistor density, TSMC’s 5nm process will also improve performance, which is the next important node.
TSMC says it consumes 30 percent less power at the same 5nm process and 15 percent less power consumption at the same performance than the 7nm process.
In addition, TSMC has an upgraded version of the N5P process, which is 7% more powerful and 15% less power consumed than the N5 process.
TSMC’s 5nm process performance is also a good thing for AMD, as AMD’s Zen4 architecture, announced earlier this month, will also use 5nm, possibly as much as it is now, with the Zen5 on the 5nm and the next generation of Zen5 using the 5nm plus process.
Unsurprisingly, the desktop version of the 5nm Zen4 architecture is the Ryzen 5000 series, and although it is not known how much of the Zen4’s IPC performance has improved, AMD’s upgrade from Zen architecture is to maintain a 10-15% IPC boost, which means 5nm Zen4’s IPC is between 20 and 32% higher than the current 7nm Zen2.
In short, if all goes well, the 2022 Ryzen 5000 series processor performance will be a step up, coupled with a steady increase in frequency, the next generation of CPU performance really want to take off.
