AMD's upcoming Ryzen 7000 (Raphael) processor is exposed. On Twitter Petykemano discovered the unknown 5nm chip in the OpenBenchmarking database.



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

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

AMD's next-generation Ryzen processors may include integrated graphics, notably RDNA 2 graphics. The Zen 4 processor contains a graphics engine dubbed "GFX1036" that runs between 1,000 and 2,000 MHz. The clock speed appears reasonable, with potential for improvement. The Radeon 680M used in Ryzen 6000 reaches 2,400 MHz.

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

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