We are still waiting for AMD to formally release its B550 chipset, though based previous leaks, we know its hardware partners have several planned B550 motherboard models. There's now even a picture of an actual B550 motherboard that is out in the wild. Not to be confused with AMD's B550A chipset for OEMs, B550 is a bit of a different beast and a true upgrade over the previous generation chipsets. Some background information is in order here. The B550A chipset is really an extension of the previous generation B450 chipset. It is only for OEM system builders, so you are not going to mosey over to Amazon or Newegg and find any B550A motherboards for sale. Technically, B550A offers support for PCI... Read more...
Are you getting tired of all the Comet Lake-S leaks and rumors? An official launch is presumably coming soon, and will put those to rest. For now, however, let's go ahead and switch things up by looking past Comet Lake-S. As in, way past it. A fresh leak points to Intel's eventual Alder Lake launch with some interesting details. Alder Lake is a few generations out. Intel is currently cranking out 10th generation Ice Lake and Comet Lake processors on mobile, and soon will launch 10th generation Comet Lake parts on the desktop. Then if past leaks pan out, we will have Tiger Lake and Rocket Lake, both likely to be labeled as 11th gen, and then finally Alder Lake, which we can assume (for now) will... Read more...
In a matter of speaking, Samsung is dipping its newest solid state drives in the fountain of youth with the promise of software that ensures these drives "never die." They are also being offered in ultra-high capacities up to 30.72 terabytes, with smaller versions cranking up the speed to 8,000MB/s for sequential reads and 3,800MB/s for sequential writes. There are a few things going on here. For one, Samsung is building new SSDs for servers that utilize the PCI Express Gen 4 (PCIe 4.0) bus, which enables much faster performance. We have already seen this in the consumer category—there are several PCIe 4.0 SSDs that promise sequential read speeds of around 5,000MB/s, when paired with an... Read more...
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.... Read more...
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... Read more...
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... Read more...
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... Read more...
