AMD Zen 3 based processors which would be arriving next year and utilize TSMC's next-generation 7nm+ process node could feature higher transistor density than Zen 2 that arrives this year. AMD's Zen 3 architecture would be featured across a wide variety of Ryzen, Ryzen Threadripper and EPYC series processors, utilizing the advanced TSMC 7nm+ node that takes advanced of the EUV tech.

AMD Zen 3 Based CPUs Could Feature 20% More Transistors Than Zen 2 - Arrives in 2020

In a report published by PCGamesN, it is mentioned that AMD's Zen 3 architecture is going to get a major transistor density boost thanks to the TSMC 7nm+ process node. Unlike the Zen 2 CPUs that utilize the TSMC 7nm node, the 7nm+ node utilizes the advanced EUV technology which would be ready for volume production in the second quarter of 2019, as reported by DigiTimes.

Taiwan Semiconductor Manufacturing Company (TSMC) is set to move 7nm EUV process technology to volume production in the second quarter of 2019, according to a recent Chinese-languageCommercial Times report.

Currently, the TSMC N7+ node is occupied for the production of HiSilicon's flagship mobile SOC and a custom version of the process, known as N7 Pro, would be utilized in the production of Apple's A13 processor for their upcoming iPhones. It is likely that AMD would like to wait out and not jump on the 7nm EUV bandwagon this early considering they are in the process of launching their Zen 2 (TSMC 7nm) processor lineup but we can expect production on the new Zen 3 chips to start at the beginning of next year.

Now according to TSMC themselves, the 7nm+ process node allows an increase of 20% in overall transistor density while increasing power efficiency by 10%. AMD could take full advantage of the process node and we could see a density boost of up to 20% in the Zen 3 architecture while having 10% better power efficiency. These changes are in addition to the architecture revamp which one should expect from the Zen 3 CPUs which will be introduced on the Ryzen and EPYC platforms in 2020 and beyond.
