However, on the 14nm node, Intel has been in use for more than four years since 2015, and the process will continue to be used until 2020. The hard-to-produce 10nm process will be first shipped in June this year, but the high-performance version of the desktop,The serverProcessors won't be available until next year.

Intel's dystocia at 10-nm nodes directly leads to a sharp problem: AMD's 7-nm Reylon 3000 processor, launched this year, will lead Intel in manufacturing technology for the first time, which has not happened for more than a decade. The last AMD technology lead will probably be pushed to the era of P4.

Today, AMD's 7Nm wafer manufacturer relies on TSMC, specifically the 7Nm HPC high-performance process. So can TSMC's 7Nm process pass the Intel process? This issue has been discussed for almost two years without any result, because there is no Taiji 7Nm HPC chip on the market, nor does Intel issue 10nm processor, so we can only talk on paper.

To solve this problem, AMD compared the 7Nm process of the old factory with the 10nm process of Intel at last year's New Horizon conference. The blue one is the process of the old factory, and the white one is the process of the friendly merchant or Intel.

As can be seen from the figure, AMD's current 12-nm process is worse than Intel's 14-nm process in performance per watt. There is no doubt that AMD's 7-nm process is better than Intel's 10-nm process in performance per watt, but it is not much higher than Intel's 10-nm process.

Intel has previously indicated that its 10-nm process is better than its rival's 7-nm process. They mainly compare the transistor density. The 10-nm process can achieve 100 million transistors per square millimeter, while the 7-nm transistor density of TSMC is slightly worse.

But considering the time point of the horizontal axis, AMD's 7Nm process has an advantage in the time to market. Intel previously said that only 10nm processors were released this Christmas shopping season, while AMD announced a 7Nm 64 core Roman processor at the end of last year.

But now things have changed. Intel will ship 10-nm processors in June, and AMD will release 7-nm Reyron processors at the end of this month, which will be officially launched in Q3 this year.
