TSMC will mass produce 5nm technology in the first half of this year. This year's capacity will be almost guaranteed by Apple A14 and Huawei's Kirin 1020 processor. Other manufacturers will queue up until next year. AMD's zen4 is in 2022 anyway.According to wikichips, the grid spacing of TSMC 5nm is 48nm, the metal spacing is 30nm, the fin spacing is 25-26nm, and the cell height is about 180nm. According to this calculation, the transistor density of TSMC 5nm will be 171.3 million per square millimeter.
Compared with 91.2 million per square millimeter of the first generation 7Nm,That's up 88%, compared with 84% for TSMC。
In addition to the increase of transistor density, the performance of TSMC 5nm process will also be improved, which is the next important node.
Compared with the 7Nm process, TSMC,At the same performance, the power consumption of 5nm process is reduced by 30%, and at the same power consumption, the performance is improved by 15%。
In addition, TSMC has the upgraded n5p process,7% higher performance and 15% lower power consumption than N5。
Not surprisingly, the desktop processor of 5nm zen4 architecture is the Ruilong 5000 series, although it is not known how much the IPC performance of zen4 has improved,But the upgrading of AMD from Zen architecture is to maintain 10-15% IPC improvementThat means that the IPC of 5nm zen4 is higher than that of 7Nm zen2 at present20-32%Between.
In a word, if the progress is smooth, the performance of the sharp dragon 5000 series processor in 2022 will reach a new level, and with the steady improvement of frequency, the performance of the next generation CPU will take off.
