AMD unveils Zen 4 for laptops, timeline for Zen 5, RNDA 3 and 4 launches. AMD has announced a roadmap to launch new GPU and CPU architectures in the coming years. This includes the transition to more advanced manufacturing nodes , and covers desktop, laptop and server components (both GPU and CPU).
The brand new Ryzen series 7000 is expected to use the forthcoming Zen 4 architecture. It is expected to provide over 15% more single-thread performance , and 8-10% more IPC (Instruments per Clock (IPC). Performance per Watt is expected to see “significant generational” improvements (25 percent or more) and a higher bandwidth for memory will increase due to the switch to DDR5. The first server and desktop components made using 5nm technology are scheduled to be launched later in the year.
The laptop chips will be produced using TSMC’s 4nm process. The new Phoenix Point will be feature Zen four CPU cores and RDNA 3 GPU CPU cores (more about this in a subsequent post). Phoenix Point is expected to be released this year. This will then be followed by Strix Point, which will make use of Zen 5 cores and RDNA 3+.

It will be built using an advanced node, which has yet to be specified.Zen 5 will be described as an “all-new microarchitecture”, but the details are not available. The company did announce that the processors will be built on both 3nm and 4nm processes.
The 4nm node at TSMC is an improved model of 5nm’s one, but the 3nm node is entirely different. First Zen 5 chips are expected by 2024. Therefore, additional details about the technology will have to be waited for.
In terms of AMD’s GPU products the next major architecture, RDNA 3, will be manufactured using 5nm technology and is the first GPU to be built using chipset designs (similar to CPUs). RDNA 2 parts were made using 7nm and 6nm processes which means that these new GPUs receive the benefits of a brand new node.
It will also include the most efficient graphics pipeline as well as improved computing units, and the latest generation of the on-die Infinity Cache. Overall, AMD expects to see the power-per-watt performance of RDNA 3 improve by 50% in comparison to RDNA 2.
