AMD updates CPU architecture roadmap, and previews the RDNA 3 architecture GPU

AMD released a new generation of Ryzen 7000 series desktop CPUs based on the Zen 4 architecture, manufactured using a 5nm process, in the live event of “together we advance_PCs” recently. The new AM5 platform supports PCIe 5.0 and DDR5 memory, and AMD promises to support the new platform until at least 2025.

At the event, AMD shared a new CPU architecture roadmap, with ticked parts indicating completed projects. In addition to the existing Zen 4 architecture that will be based on the 5nm process, there will also be a 4nm process CCD in the future. It is reported that the mobile SoC and the Zen 4c architecture CPU for cloud computing will use the 4nm process. Whether it is 5nm or 4nm, they belong to the same process node, similar to 14/12nm and 7/6nm. Probably in late 2023 or early 2024, it is possible to see the first Zen 5 architecture products, continue to use the 4nm process, and then move to the 3nm process.

Like the Zen 3 architecture, the Zen 4 architecture will also have a version with 3D Vertical Cache (3D V-Cache) technology. It was previously reported that the Zen 4 architecture uses the second-generation 3D V-Cache technology, which will have higher bandwidth and improved latency. It is likely to be fabricated on a 6nm process, which also brings an additional 64MB of cache to each Zen 4-based CCD.

In addition to the CPU, AMD will also make a big move in GPU this year, launching the Radeon RX 7000 series based on the RDNA 3 architecture. AMD didn’t reveal much at the event, but said it would provide more than 50% performance-per-watt improvement over the current RDNA 2 architecture. AMD used a platform built with a new generation of graphics cards to demonstrate, with the latest Ryzen 9 7950X. In addition, the hazy photos of the public version of the graphics card show that a black-based color scheme will be used in the design, but it is unclear which model and external power supply configuration.
