AMD Ryzen 8000 “Zen 5” CPUs and Radeon RX 8000 “RDNA 4” GPUs Likely to Leverage TSMC’s 4nm Node

AMD’s Ryzen 8000 CPUs may be redesigned to fabricate TSMC’s 4nm node as the progress of the 3nm (N3) node forces chipmakers to alter their roadmaps. The primary architectures to take advantage of TSMC’s 3nm node include the Zen 4 CPU core (Ryzen 7000/8000), RDNA 4 (Radeon 8000), Intel ARC Battlemage, and the GPU chiplets for Meteor/Arrow Lake.

According to Greymon55, one of the most reliable sources on AMD’s future processors, the next-to-next-gen Ryzen 7000/8000 CPUs and Radeon RX 8000 GPUs may be downgraded to adopt TSMC’s 4nm (N4) node, a refinement of the 5nm (N5) node. Both these microprocessor families are expected to be a mild upgrade, much like Zen 3 and RDNA 2, bringing moderate performance and efficiency gains.

In comparison, the RDNA 3-powered Radeon RX 7000 GPUs, and the Zen 4-based Ryzen 7000 CPUs leveraging TSMC’s 5nm node will be a major update to AMD’s CPU/GPU cores, overhauling the architecture, I/O, and packaging. The switch to the AM5 platform and DDR5 memory facilitates much of these gains.

Zen 5 and RDNA 4, on the other hand, will both be incremental updates, refining the power, and clocks, in addition to the memory subsystem. It’s hard to predict the exact impact of a node downgrade on a generational upgrade, but the power efficiency is likely to take a hit.
