When AMD officially unveiled the Ryzen 9000 series processors last month at Computex 2024, I was surprised not because of the announcement itself – it was already an open secret that AMD will be launching new desktop processors – but that it will be launched as soon as this month, July. Much sooner than many of us had anticipated.
At the recent Zen 5 Tech Day held in Los Angeles, AMD took a deep dive with selected members of the media including HardwareZone into their upcoming Zen 5 architecture – the fifth generation of AMD’s Zen CPU architecture that powers its next-gen processors for desktops, mobiles and servers, including the Ryzen 9000 series and the mobile-focused Ryzen AI 300 processors.
The new Zen 5 architecture, which I got to see in action promises to be a significant leap forward. According to AMD’s chief technology officer, Mark Papermaster, Zen 5 is a foundational shift, much like the original Zen architecture. This isn’t just marketing fluff – there are some substantial changes under the hood.
One of the standout improvements is the new branch prediction system that features dual decode pipes. AMD says this enhancement boosts the throughput for the branch prediction engine, reducing latency and increasing accuracy. AMD has also expanded the number of dispatch and execution engines to an 8-wide design, allowing the processor to handle more instructions per clock cycle.
