AMD is out there living the good life right now. Zen has proven to be a formidable contender, it seems like a Zen 2 refresh is en route, and looking further down the road, Zen 3 will likely keep the party going. As it pertains to the latter, a new leak potentially sheds some light on what AMD has on tap, both for its upcoming CPUs and APUs. All indications point to Zen 3 being on track for a release later this year. It will leverage an enhanced 7-nanometer node, which AMD and TSMC are not referring to as 7nm+, and is expected to deliver a nice bump in IPC (instructions per clock) performance. We can also expect better power efficiency and some new features. Beyond those things, here is the supposed...

The USB4 spec is getting better and better with each new announcement from the Video Electronics Standards Association (VESA). The latest update from the standard body concerns the DisplayPort Alt Mode 2.0 spec, which is being implemented for USB4. As you might already know, USB4 continues the use of the USB Type-C connector that we've already grown accustomed to with current Thunderbolt 3 accessories and is featured on the bottom of nearly every new Android smartphone that has been announced over the past few years. Alt Mode 2.0 allows the USB-C connector to shuttle DisplayPort video data -- along 4 lanes -- at 80Gbps downstream. Previously, USB4 data speeds were capped at...

The USB Implementers Forum (USB-IF) has announced the USB4 specifications have been published. USB4 is hailed as a significant update that will deliver next-generation USB architecture that complements and builds upon the existing USB 3.2 and USB 2.0 architectures. USB4 is based on the Thunderbolt protocol specification that was contributed recently by Intel and the USB Promoter Group. USB4 promises to double the maximum aggregate bandwidth of USB and enables simultaneous data and display protocols. Development of USB4 specifications started in Q1 2019 and is now officially available for download here [ZIP]. USB4 offers two-lane operation using existing USB Type-C cables and supports...

The USB Promotors Group has just officially announced the arrival of the USB4 specification, which will supersede the newly formed (and highly confusing) USB 3.2 protocol. USB4 promises to double the transfer speeds of USB 3.2 thanks in part to a critical move made by Intel. Intel has made its Thunderbolt 3 protocol royalty-free, which will allow competing chipmakers to offer implement the standard at lower costs. It also means that USB4 is based on the underlying Thunderbolt 3 protocol. As a result, maximum speeds for USB4 double to 40 Gbps using existing certified cables, matching the speeds offered by Thunderbolt 3. “By collaborating with the USB Promoter Group, we’re opening the...
