According to recent industry reports, AMD would work with TSMC to develop an adapted version of the 5nm node specifically for their 2021 products. This would allow them to optimize the process for their products to reduce power consumption and maximize frequencies.
This is something Nvidia has been doing for several years and has proven to be very effective, exceeding the power consumption and performance of AMD GPUs by up to 100%. This is due to the use of Nvidia FinFet, a method developed exclusively for Nvidia, rather than using a generic method. Now AMD wants to do the same for both its processors and graphics cards and is trying to maximize the performance and frequencies of its chips to be as competitive as possible.
This new process would be used for the first time on the Zen 4 processors and RDNA3 graphics, which will be launched at the end of next year, allowing AMD to position itself in a solid way in both markets. It will be interesting to see the evolution of power consumption, especially in graphics, thanks to the use of a custom 5 nm process, although we’ll have to wait almost a year and a half.
There is no official confirmation yet, so this information must be taken with a pinch of salt. At the moment they are only rumours, although it would, of course, be good if they became reality.
