The USB Promoter Group has announced the pending release of the USB4 specification, a major update of USB architecture that builds on the existing USB 3.2 and USB 2.0. It doubles the bandwidth of USB and enables multiple simultaneous data and display protocols. The USB4 architecture is based on the Thunderbolt protocol specification recently contributed by Intel.
The new USB4 architecture defines a method to share a single high-speed link with multiple end device types dynamically. This ensures that the connections best serve the transfer of data by type and application. As the USB Type-C connector has evolved into the role as the external display port of many host products, the USB4 specification provides the host
“The primary goal of USB is to deliver the best user experience combining data, display and power delivery over a user-friendly and robust cable and connector solution,” said Brad Saunders, USB Promoter Group Chairman. “The USB4 solution specifically tailors bus operation to further enhance this experience by optimizing the blend of data and display over a single connection and enabling the further doubling of performance.”
Key characteristics of the USB4 solution include:
- Two-lane operation using existing USB Type-C cables and up to 40 Gbps operation over 40 Gbps-certified cables
- Multiple data and display protocols to efficiently share the total available bandwidth over the bus
- Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3
With over 50 companies actively participating in the final stages of review of the draft specification, the USB4 specification is on track to be published around the middle of 2019. Coincident with the release of the USB4 specification, the release of an updated USB Type-C Specification will be made to comprehend USB4 bus discovery, configuration and performance requirements.
USB Developer Days 2019, in the second half of this year, will include detailed technical training covering the USB4 specification and the latest for USB Type-C, USB Power Delivery, and other exciting topics.
This update is part of the USB performance roadmap and is specifically targeted to developers at this time. Branding and marketing guidelines will be established after the final specification is published.
“Releasing the Thunderbolt protocol specification is a significant milestone for making today’s simplest and most versatile port available to everyone,” said Jason Ziller, general manager of Client Connectivity at Intel. “By collaborating with the USB Promoter Group, we’re opening the doors for innovation across a wide range of devices and increasing compatibility to deliver better experiences to consumers.”
“USB4’s high throughput and advanced features enable new scenarios in consumer, enterprise, and intelligent edge markets, while maintaining interoperability with existing USB and Thunderbolt 3 devices,” said Roanne Sones, Corporate Vice President, Microsoft OS Platforms. “We are excited to work with our partners in the ecosystem to bring USB4 to market and showcase its benefits.”
ASUS puts more screen into gaming
While others battle over the thinnest bezel for maximizing screen space, ASUS released a dual screen laptop that uses the space where one’s palms would usually rest, writes BRYAN TURNER
When one imagines dual screen, it’s usually two screens side-by-side on a desk, providing a horizontally long desktop experience. There have been clunky dual screen laptops in the past, some that folded out horizontally, but these never really caught the attention of the consumer.
Enter Asus with the ROG Zephyrus Duo 15. Like the Asus ZenBook Pro Duo, the ROG Zephyrus Duo features two screens – the main screen on the top panel (as we’re all used to) and another screen just below that, where the top of the keyboard would usually be. The main difference is the secondary screen pops out at a 13-degree angle to bridge the gap between the two screens, and to give better viewing angles.
That ZenBook Pro Duo is also a pretty good machine for gaming, because it features Nvidia GeForce RTX 2060 graphics, but it doesn’t have the latest graphics. With the new machine, Asus is one of the first manufacturers to release a laptop featuring Nvidia’s latest RTX 2080 Super Max Q GPU for mobile devices. This is a momentous feat, considering that not only are the external features cutting edge, but also the internals.
The main panel is configured to be either 4K 60Hz or 1080p 300Hz. The former is most likely going to be picked up by video editors and photoshop gurus, because it covers 100% of the Adobe RBG colour space, and the latter will appeal to gamers who want to see their high frame rates in action. Both panels are Pantone Colour Calibrated for high colour accuracy.
The secondary panel features a 32:9 resolution, which is equal to putting two standard 16:9 widescreen panels together. The touchscreen panel outputs a 3840 x 1100 resolution at 60Hz.
The combination of these panels will be ideal for portable gamers. The main game can be on the main panel, while Discord and game streaming software can be on the secondary panel, all at a glance. Not to mention the game developers that have support for two screens, where the second screen highlights stats and other components that had to be crammed into the main screen’s space.
On the inside, the laptop features liquid metal cooling, which lowers the temperatures by 8°C and allows the computer to function with less fan noise. Asus has also slipped some very interesting cooling tech behind the secondary panel, when it pops open, to maximise airflow into the computer from both the bottom and the top of the device.
The laptop features the biggest battery Asus has yet put in a computer, at 90Wh. This is incredibly close to the Transportation Security Administration (TSA’s) limit of 100Wh batteries being allowed on flights to the US. Fortunately, this computer can be taken around the world if necessary.
These computers will come in two variants of 10th Generation Intel processors, namely the i9-10980HK or i7-10875H. They support up to 2 M.2 NVMe PCIE 3 slots for SSDs.
The new ROG gaming range from Asus will be available later this year. The price of the computer has not yet been confirmed
Vodacom, Discovery launch free virtual COVID-19 tests
Vodacom and Discovery have teamed up to launch free virtual COVID-19 testing for all South Africans – not only for their customers.
Vodacom and Discovery have partnered to deliver a powerful online healthcare platform for the benefit of all South Africans during the COVID-19 pandemic. This platform provides easy access to a COVID-19 risk tool for all South Africans, to help understand your personal risk for COVID-19. Where needed, it assists immediately to schedule virtual healthcare professional consultations and get advice.
Globally, telemedicine has proved to be vital in the management of this disease, with many governments and healthcare systems advocating for digital healthcare tools and virtual consults to be the first step and primary means of healthcare support during the COVID-19 outbreak. The risk assessment and virtual healthcare tools can help to identify people who need health professional engagement and a potential referral for testing or to a hospital.
The online healthcare platform therefore makes it possible for South Africans to access a healthcare professional without them having to travel to a healthcare facility.
This reduces overcrowding at clinics and doctors’ rooms where there is greater risk of the virus spreading. It also protects healthcare professionals from potential repeated exposure to COVID-19.
It is free to use and available on any web browser or mobile phone to facilitate a full consultation with a doctor, either through video calls, voice calls, or by text. The service can be accessed by visiting either the Discovery or Vodacom websites. Vodacom customers can get additional information and do a self-assessment via USSD by dialling *111#.
Through a partnership with Vodacom, Discovery’s existing DrConnect platform, which was previously available only to Discovery clients, is now accessible to all South Africans. Vodacom and Discovery have also jointly created a fund to pay doctors for approximately 100,000 consultations, making them free to any South African.
There are seven easy steps to use an online doctor consultation:
- Start the process by visiting Discovery’s COVID-19 information hub or Vodacom’s website. Members of Discovery Health Medical Scheme can access the service through the Discovery app. Vodacom customers can get additional information and do a self-assessment via USSD by dialling *111#.
- Utilise the COVID-19 self-screening risk assessment tool, by answering a few easy questions.
- If you are confirmed as high risk of having COVID-19, a short registration and consent process on the DrConnect app will follow.
- Book a virtual consultation with a doctor who is available to assess the need for COVID-19 testing.
- If the doctor recommends testing, a photo of the completed pathology form will be sent to you by SMS, WhatsApp or email. The same process will apply to scripts for medicine.
- Testing and collecting of medicine will be facilitated by the relevant essential healthcare service providers that you must visit.
- Doctors will receive test results electronically and can then advise if you should schedule follow-up appointments to discuss results and next steps.
The Vodacom COVID-19 information hub contains other up-to-date information for consumers about COVID-19.
With virtual consultations, the location of the doctor or the location of the patient will not restrict access to fast and effective healthcare. All doctors can register to help.
