AMD Zen 4 CPU with 5.2GHz Boost Cores and RDNA 2 iGPU

AMD’s upcoming Ryzen 7000 (Raphael) processor has been revealed. Petykemano on Twitter discovered an unknown 5nm chip in the OpenBenchmarking database.

The Ryzen 7000 processor has eight Zen 4 cores with synchronous multithreading (100-000000666-20 Y) (SMT). A Zen 4 chip with a similar definition was seen in January. The eight-core, 16-thread part should be the Ryzen 7 7800X, the successor to the popular Ryzen 7 5800X. For Halo Infinite, AMD has teased the Ryzen 7000 CPU with an overall boost rate above 5GHz.

The OpenBenchmarking Zen 4 processor is an engineering prototype, but the 5.21GHz boost clock is impressive. It outperforms any mainstream AMD chip currently available. For example, the Ryzen 9 5950X beats at 4.9 GHz, while the Ryzen 7 5800X beats it at 4.7 GHz. Raphael also shows what AMD can do with Zen 4 on TSMC’s 5nm technology. According to the Taiwanese foundry, the N5 node is 30% more power efficient or 15% faster than the 7nm node used in AMD’s current Ryzen 5000 (Vermeer) series.

AMD’s next-generation Ryzen processors may include integrated graphics, particularly RDNA 2 graphics. The Zen 4 processor has a graphics engine dubbed “GFX1036” that runs between 1000 and 2000MHz. Clock speed seems reasonable, with potential for improvement. The Radeon 680M used in the Ryzen 6000 reaches 2400MHz.

AMD’s RDNA 2 graphics engine is used in Radeon RX 6000-series (Big Navi) and Ryzen 6000 (Rembrandt) processors. The GFX1036 obviously belongs to the RDNA 2 family. AMD has just added the GFX1036 and GFX1037 graphics IP blocks to the RadeonSI Linux driver, according to Voronex. AMD’s Van Gogh, Navi 24 (Beige Goby) and Rembrandt (Yellow Carp) mobile CPUs all get the same treatment. Splinter-RPL (WS22427N000 BIOS) may be the code name for the AM5 reference platform. Unfortunately, the story just mentioned 16GB. Various sources say that the AM5 platform will only support DDR5 memory, making it a premium platform given the high cost of early DDR5 memory clusters. With its 12th generation Alder Lake processors, Intel allows users to choose between DDR4 and DDR5.

AMD’s latest roadmap announced the Ryzen 7000 for release late in the year. But Raphael’s mobile counterpart, Dragon Range, won’t arrive until 2023.
