Get Ready: AMD Navi 48 Hints at Powerful New GPUs

ROCm is an open-source software platform, crafted with a commitment to flexibility and high performance. It is designed for accelerated computing across various programming languages, empowering participants from the machine learning and high-performance computing communities to expedite code development through an array of open-source computing languages, compilers, libraries, and redesigned tools. It is particularly well-suited for large-scale computations and supports multi-GPU computing. In recent months, AMD has accelerated the pace of continuous updates to the ROCm software stack, introducing enhanced support and a broad range of optimization changes, especially aimed at boosting computational capabilities in the artificial intelligence (AI) sector.

Recently, enthusiasts have uncovered that AMD has introduced the first batch of patches for its next-generation GPUs, including build targets and initial configuration files, now integrated into the ROCm validation suite. The debut RDNA 4 architecture GPU is identified as “NV48”, shorthand for Navi 48. Unfortunately, specific details regarding its specifications were not disclosed. This is not the first instance where new GPU information has emerged through ROCm, as similar revelations occurred with the RDNA 3 architecture’s Navi 31/32/33.

It is understood that the RDNA 4 architecture will mark AMD’s first consumer-grade product to support the PCIe 5.0 interface, with a likelihood of featuring GDDR7 memory. Past rumors have suggested that the Navi 4x series GPUs, based on the RDNA 4 architecture, will not include high-end models, indicating an absence of Radeon RX 8000 series graphics cards akin to those equipped with Navi 21/31, and more reminiscent of past RDNA or Polaris architectures.

Rumors indicate that the RDNA 4 architecture GPUs will comprise only two chip models, with Navi 48 featuring 32 Workgroup Processors (WGP) and the lesser-spec Navi 44 boasting 20 WGPs.
