AMD recently confirmed that Zen CPU architecture for Ryzen processors is expected to last four years. The Ryzen microprocessor took AMD four years to progress and it is the same length the company expects it to survive in its ongoing war with Intel.

Mark Papermaster, AMD's chief technology officer, confirmed the four-year lifespan in a conversation with PCWorld at CES 2017 in Las Vegas. The CTO, however, declined to discuss the specifics. He added that AMD would not shadow Intel's Tick-Tock model and instead go for Tock, Tock, Tock. This means that the company is planning to pursue plans of future revisions of Zen with an enhanced architecture to better performance and efficiency. These planned revisions will be applied on Zen, on their consumers, and on their workstation processors.

AMD's Ryzen, the CPU brand that is the public image of Zen chip microprocessors, arrives at a particularly unexpected time. Competitor Intel recently launched its conventional quad-core Kaby Lake microprocessors, and the chips met mixed reviews from the tech press. In some way, that is because Intel's famous tick-tock manufacturing model faltered, which resulted in a third 14nm chip, Kaby Lake, instead of the previously anticipated two.

Meanwhile, AMD toiled hard creating a fresh method, targeting and apparently hitting a 40 percent performance enhancement target, compared to its previous chip architecture, Excavator. The combination of a comparatively mild Intel launch and a sweeping new architecture has AMD executives and enthusiasts talking over PC processor competition market for the first time in years.

AMD does not see any principal threats from Intel that may directly affect Zen's launch. The PC gaming and enthusiast community met Zen positively. Ryzen is preparing to be the processor series that AMD and PC gaming fans have long been anticipating. Wccftech notes that the coming Zen+ cores will ensure that the performance of Zen-based chips keeps progressing and will deliver the best possible efficiency.
