AMD Zen 4 will not support PCI Express 5.0

   PCIe 4.0 introduced in 2017, is the fourth generation of the protocol to connect peripherals to the motherboard (The most popular today is still PCIe 3.0) and doubles the bandwidth for graphics cards, HDDs , SSD, Wi-Fi and Ethernet vs. PCIe 3.0. However, it seems that this generation is starting to become obsolete as Intel prepares to introduce a PCIe 5.0 generation version, which will launch at the same time as the Alder Lake processors.
   Similar to the change from PCIe 3.0 to 4.0, the PCIe 5.0 standard will also double the magnetic transfer speed compared to the existing PCIe 4.0. The PCIe 5.0 standard supports speeds of 32 GT/s, which is about 4GB/s per lane, or 128GB/s total compared to the 16GT/s bit rate of PCIe 4.0 (64GB/s).
   In other words, the PCIe 5.0 protocol will work on a motherboard that supports PCIe 4.0, and the PCIe 5.0 protocol will also work on a PCIe 3.0 motherboard, but they are limited to the performance of the PCIe 3.0 protocol.
   According to leaked information from hackers infiltrating the server system of the world's largest component maker Gigabyte, AMD's upcoming processor line with the code name Raphael will not support the PCI Express version. Latest.
   AMD first introduced PCI Express 4.0 support on its Ryzen 3000 processors and was ahead of its competitor Intel. However, this will not happen again because the new generation of Alder Lake processors, Intel will introduce the PCIe 5.0 standard.    Meanwhile, leaked documents from Gigabyte show that the upcoming AM5 platform will still use PCI Express 4.0.
   The upcoming Zen 4 codenamed Raphael will offer 28 PCI Express 4.0 lanes, four more than the current Ryzen 5000 series. In contrast to AMD, Intel's upcoming Alder Lake processors have a total of 20 lanes, 16 of which use the PCI Express 5.0 standard.
Unlike PCI Express 4.0, when it is first introduced to the public, related products will be available for use, such as VGA or SSD.    With PCI Express 5.0 being introduced on Intel's upcoming microprocessor platform, it will be primarily dedicated to graphics cards, but there are currently no cards that support this interface.
