AMD Zen 5 CPUs Leaked: Granite Ridge Specs Revealed

AMD is poised to unveil its groundbreaking Zen 5 series architecture in 2024, progressively phasing out the Zen 4 series. The Zen 5 lineup, dubbed “Granite Ridge,” will succeed the Ryzen 7000 series, codenamed “Raphael,” and will continue to be compatible with the AM5 platform.

Recent discoveries by tech enthusiasts have unveiled a shipment list for the engineering sample of Granite Ridge, revealing two new AMD product codes (OPN) for models with six and eight cores, respectively:

  • 100-000001290-21: 6-core, 105W, A0 stepping
  • 100-000001404-21: 8-core, 170W, B0 stepping

While AMD has not yet announced a release date for its next-generation desktop processors, it’s highly anticipated that Dr. Lisa Su, the CEO, will shed light on the Zen 5 series architecture during her keynote at COMPUTEX 2024 on the morning of June 3rd. Rumors suggest that compared to the Zen 4 architecture, Zen 5 could offer a 10% to 15% increase in instructions per cycle (IPC).

The Ryzen series, based on Granite Ridge, closely resembles the existing Ryzen 7000 series, with configurations up to 16 cores and 32 threads. These processors have a thermal design power (TDP) range from 65W to 170W and are equipped with up to 16MB of L2 cache and 64MB of L3 cache. The specific manufacturing process for the Granite Ridge CCD remains under wraps, though there are indications it might utilize a 4nm process. It’s expected to inherit the I/O die (IOD) from Raphael, which includes 28 PCIe 5.0 lanes, a DDR5 memory controller, USB functionality, and integrated graphics based on the RDNA 2 architecture, manufactured using TSMC’s 6nm process.
