AMD GPU Roadmap 2022-2024 confirms next-gen RDNA 4 "Radeon RX 8000" GPUs and CDNA 3 "Instinct MI300" APUs by 2024

AMD has confirmed its RDNA 4 “Radeon RX 8000” next-gen gaming GPUs and CDNA 3 “Instinct MI300” data center APUs in its latest roadmap.

AMD GPU Roadmap 2022-2024 confirms RDNA 3 for gaming chips “Radeon RX 8000” and CDNA 4 for “Instinct MI300” chips

While AMD unveiled the first details of its next-gen RDNA 3 GPUs, they also unveiled the generation of gaming GPUs that is coming after it, and surprisingly it’s called RDNA 4.

AMD RDNA 4 gaming GPUs are coming by 2024

Expected to launch in 2024, the new Navi 4x range will be based on an advanced process node. For its CPU lineup, AMD has announced both 4nm and 3nm nodes, so it could be any of those nodes, but I’d bet on the 4- set nm nodes which will make for some good marketing. AMD didn’t share numbers, but at least we know that RDNA 4 is a real thing and is coming after RDNA 3.

Rumor has it that RDNA 4’s MCM GPUs will include two different processing nodes similar to RDNA 3. The RDNA 4 architecture will power the Navi 4X line of GPUs, and the flagship chip, the Navi 41, was leaked a year ago. The information states that the RDNA 4 series, which will power the Radeon RX 8000 series graphics cards, will share a common architecture and will not split them into two different architectures as expected with RDNA 3.

There are reports that AMD’s RDNA 3 graphics architecture will only be featured on the Navi 31, 32 and possibly the Navi 33 GPU, while the rest of the lineup will be based on an RDNA 2 refresh. The top GPUs Navi 31 and Navi 32 RDNA 3 feature an MCM architecture and use a 5nm node for the GCD (Graphics Compute Die) and a 6nm node for the MCD (Multi-Cache/IO Die ). The RDNA 2 refresh GPUs are based on a 6 nm process node and are presented as a refresh within the new graphics family.

For RDNA 4, it looks like AMD plans to use the same graphics architecture across its Navi 4X lineup and no updates from older GPU architectures like RDNA 3 or RDNA 2. AMD will use two different nodes for its MCM chips, such as the Navi 41, namely 5nm and 3nm. The GCD is based on the 3nm process node while the MCD is based on the 5nm node. With RDNA 3 scheduled to launch in late 2022, the RDNA 4 lineup will launch sometime in 2024, competing against the successor to NVIDIA’s Ada Lovelace and Intel’s ARC Battle Mage or Celestial.

AMD’s next generation cDNA 4 “Instinct MI300 APU” by 2023

David Wang also announced the Compute GPU roadmap, which includes Instinct-class chips for the AI ​​and data center segments. It can now be confirmed that AMD is indeed working on a multi-chip and multi-IP Instinct accelerator that will not only feature the next generation of CDNA 3 cores, but also come with Zen 4 CPU cores of the equipped with the next generation. The Instinct MI300 GPU (technically an APU) is slated to launch by 2023.

As for the details, AMD will use the 5nm process node for its Instinct MI300 “CDNA 3” GPUs. The chip will be equipped with the next generation of Infinity Cache and features the 4th generation Infinity architecture, which enables the support of the CXL 3.0 ecosystem.

The Instinct MI300 accelerator will rock a unified memory APU architecture and new math formats that allow for a 5x performance per watt increase over CDNA 2, which is huge. AMD also predicts over 8x AI performance compared to the CDNA 2-based Instinct MI250X accelerators.

The CDNA 3 GPU’s UMAA connects the CPU and GPU to a unified HBM memory package, eliminating redundant memory copies while delivering a low total cost of ownership.
