SSDs and GPUs are making speed increases as the new standard doubles bandwidth
PCI Special Interest Group (PCI SIG) has announced the release of the PCI Express (PCIe) 6.0 specification, which promises doubling of bandwidth and PCIe 5.0 interface power efficiency in modern day CPUs. -today and solid state drivers (SSDs).
The main specification for the expansion bus used to connect CPUs and motherboards to graphics cards, Wi-Fi and SSDs is PCIe, and the PCIe Gen specification should be a new update to the bandwidth standard 5 doubled to a raw data rate of 64 Giga Transfers each. second (GT / s), according to PCI SIG.
PCIe 6.0 has a bandwidth of 128 Gygabytes per second (GB / s) in one direction on 16 lanes, which goes down to 8 GB / s on a single lane.

This release is a more important revision than PCIe 4.0 and 5.0 and is arguably the largest in the history of the 19-year phase, thanks to new signal technologies such as Pulse-Amplitude Modulation 4 (PAM4). ) and its flow control unit (FLIT). coding, according to AnandTech.
Like previous releases of the PCIe specification, PCIe 6.0 will be compatible with previous PCIe notifications, allowing older devices to work in newer hosts and vice versa.
Devices with a PCIe 6.0 interface will not be available in products for a few years and, at the very least, it is up to the hardware vendors to implement the new standard.
However, as an indicator, PCI SIG released PCIe 5.0 in 2022 and only started appearing in Intel's new 12th Alder Lake with up to 16 series of PCIe Gen 5 while Samsung launched first state-of-the-art hard drive (SSD) driver launched with the PCIe 5.0 interface in December. PCI SIG states in FAQ that it expects products with PCIe 6.0 to be available in product 12 to 18 months after the final specification is released.
The new release will initially target servers, artificial intelligence, data centers, high-performance computing, business, automotive, and military and aircraft applications. It may take several more years for it to reach consumer hardware.
