Sure, there are many PC users out there pining for a hard-to-find AMD Ryzen 5000 series desktop CPU to build a new system around, and on the mobile front, AMD's latest generation Zen 3 stack is brand new as well. But even so, the rumor mill remains in full swing regarding what sits further down the road. Specifically Zen 4, along with a codename we have never seen attached to an AMD product before. That would be "Phoenix," which according to software engineer and prominent leaker Partick Schur, is the codename for AMD's next round of APUs (accelerated processing units).

It may seem hard to believe, but storage makers are already approaching the limits of the PCI Express 4.0 bus in a typical NVMe drive, with the latest controller designs pushing transfer speeds in the neighborhood of 7 gigabytes per second (GB/s). That being the case, Silicon Motion is already at work developing controllers that leverage the PCI Express 5.0 bus. Before we get to that, let's go over the bandwidth limits of each PCI Express specification to date, starting with PCI Express 1.0... PCIe 1.0: 2.5GT/s transfer rate, 250MB/s per lane bandwidth, 4.0GB/s x16 bandwidth PCIe 2.0: 5.0GT/s transfer rate, 500MB/s per lane bandwidth, 8.0GB/s x16 bandwidth PCIe 3.0: 8.0GT/s transfer rate, 1GB/s...
