One of the exciting things that AMD's third-generation Ryzen processor family and accompanying X570 chipset will usher in is support for PCI Express 4.0. This offers double the bandwidth of PCI Express 3.0, paving the way for faster graphics and speedier storage drives. To help measure the impact that PCie 4.0 can have, UL Benchmarks is adding a new test to its 3DMark suite. It's actually a PCI Express feature test, meaning users will be able to run it on any modern platform, including existing PCie 3.0 motherboards. Users who dive into a newfangled Ryzen setup using the latest processors and motherboard options, however, will obviously see a better benchmark score, for whatever that is worth....

Companies are getting a jump on Computex by announcing a spattering of upcoming products ahead of the event, which gets underway on Tuesday, May 28. Count Gigabyte among them. One of the things Gigabyte plans to show off is a new solid state, though it's not like any SSD that is currently available. How so? According to Gigabyte, it's the world's first PCI Express 4.0 M.2 SSD. There is a bit to unpack among all that technobabble, so lets get started. M.2 refers to the form factor. Unlike 2.5-inch SSDs that require a power cable and SATA cable, M.2 drives are those gum stick-sized SSDs that plug directly into the motherboard, provided it has an M.2 slot. These can be either SATA or NVMe. An example...

The dust has barely had time to settle on AMD's X470 chipset, which launched alongside its second-generation Ryzen processors. Looking ahead, however, X570 is now right around the corner, or so the latest leak says. One thing that's interesting about the upcoming chipset is that it supposedly will offer PCI Express Gen 4 support. If the X570 does indeed end up supporting PCIe 4.0, as the latest leak indicates, it will be AMD's first chipset to do so, and the first consumer platform in general. It also stands to reason that AMD's upcoming Zen 2 processors (Ryzen 3000 series) will support PCIe 4.0 too. Whether the leaked information is accurate or not, it's impossible to say (AMD doesn't talk about...

The PCI standards group PCI-SIG (Special Interest Group) comprised of AMD, Intel, NVIDIA, and other technology bigwigs announced it has finalized the specifications for the PCI Express 4.0 standard. It has previously announced in June at the group's DevCon event that the spec was feature complete and undergoing review. Now several months later PCI Express 4.0 is finalized, and fast. PCIe 4.0 offers a transfer rate of 16GT/s with flexible lane width configurations. That is double the raw bitrate of PCIe 3.0 and more than triple the bitrate of PCIe 2.0. In full duplex mode, that translates to around 64GB/s of bi-direction x16 bandwidth, whereas PCIe 3.0 topped out at around 32GB/s, and PCIe 2.0...
