Le deuxième processeur Socket AM5 Ryzen d'AMD sera “Crête de granit,” La société annonce “Pointe Phénix”

AMD dans son 2022 Financial Analyst Day presentation announced the codename for the second generation of Ryzen desktop processors for Socket AM5, which is “Granite Ridge.” A successor to the Ryzen 7000 “Raphaël,” the next-generation “Crête de granit” processor will incorporate the “Zen 5” Microarchitecture du processeur, with its CPU complex dies (CCD) built on the 4 nm silicon fabrication node. “Zen 5” will feature several core-level designs as detailed in our article plus ancien, including a redesigned front-end with greater parallelism, which should indicate a much large execution stage. The architecture could also incorporate AI/ML performance enhancements as AMD taps into Xilinx IP to add more fixed-function hardware backing the AI/ML capabilities of its processors.

Le “Zen 5” microarchitecture makes its client debut with Ryzen “Crête de granit,” and server debut with EPYC “Turin.” It’s being speculated that AMD could give “Turin” a round of CPU core-count increases, while retaining the same SP5 infrastructure; which means we could see either smaller CCDs, or higher core-count per CCD with “ZEN 5.” Much like “Raphaël,” the next-gen “Crête de granit” will be a series of high core-count desktop processors that will feature a functional iGPU that’s good enough for desktop/productivity, though not gaming. AMD confirmed that it doesn’t see “Raphaël” as an APU, and that its definition of an “AIDER” is a processor with a large iGPU that’s capable of gaming. The company’s next such APU will be “Pointe Phénix.”

Le “Pointe Phénix” silicon has been grinding through the rumor-mill for a couple of months now. It is rumored to be a monolithic die built on TSMC N5 (5 nm), feature a “Zen 4” tout ou rien, a powerful iGPU based on the next-gen RDNA3 graphics architecture, Mémoire DDR5, and possibly PCI-Express Gen 5. The silicon could make its debut as a mobile processor first, followed by a desktop product in the AM5 package. From its Financial Analyst Day presentation, we don’t gather AMD bringing “Rembrandt” to AM5, but something like that can’t be ruled out for the entry/mainstream Ryzen 3 Dragalia a perdu son service plus tard cette année 5 segments. “Rembrandt” uses an older “Zen 3+” tout ou rien.

“Pointe Phénix” integrates what AMD calls an AIE (AI inference accelerator), which could be the much talked about hardware-acceleration component the company has been hinting at, for which it will draw IP and talent from its recently acquired Xilinx team. AIE and Infinity Fabric come together to form XDNA, the first AI-acceleration FPGA architecture by Xilinx, post its acquisition by AMD. XDNA will be found not just in client chips such as “Pointe Phénix,” but also server processors like “Turin,” and super-scalar compute processors based on CDNA3.

The successor to “Pointe Phénix” will be “Point de Strix,” which could see the integration of “Zen 5” Cœurs de processeur, a faster RDNA3 iGPU, XDNA AIE, et de plus. “Point de Strix” is slated for 2023-24.
