Early Talk on AMD's RDNA 5 / UDNA GPUs Show What Might Come
The first bits on AMD's fresh RDNA 5 (also called UDNA) graphic setups have come out by known leaker Kepler_L2. This leak shows plans for a three-level GPU set and hints at a move back to a single die design for the new series.
Talked-About RDNA 5 / UDNA GPU Builds
The core of the leak hints at three die setups that look like past AMD models yet use a new build. The planned specs are:
- Top-Level Die (Navi 5X) 96 Compute Units (CUs) with a 384-bit memory lane.
- Mid-Level Die (Navi 5X) 64 Compute Units (CUs) with a 256-bit memory lane.
- Base-Level Die (Navi 5X) 32 Compute Units (CUs) with a 128-bit memory lane.
Goals and Design Ideas
From the info, the highest RDNA 5 / UDNA GPU aims to hit power between an NVIDIA GeForce RTX 4090 and RTX 5080, likely in making images. This spot shows it as a top-end card but not a head-to-head rival to NVIDIA's top "90-class" items.
A key part in the rumor is AMD's said move back to a whole GPU die for this make, leaving the multi-chip setup (MCM) used in some past top cards. This change is seen as a big step for AMD's GPU area, aiming for a strong, simpler core design to start a new base.
The 384-bit memory lane on the best one could also let for bigger VRAM sizes, maybe up to 32 GB if 3 GB GDDR7 memory parts come into play.
Backstory and Likely Times
It's key to note that Kepler_L2 has given these setups as a "guess," meaning they are unsure and may change. This info is not an official word from AMD.
The plans for this fresh gaming build hint that mass making could start in the second part of 2026. This would set its launch in a tough field, with likely NVIDIA "SUPER" series updates and Intel's "Big Battlemage" GPUs.
