Zotac unveiled the VR GO 4.0 backpack computer based on Intel Tiger Lake and NVIDIA RTX A4500

Zotac announced the VR GO 4.0, its fourth generation gaming backpack computer.
The manufacturer is positioning the unusual device as a gaming system for virtual reality.
Externally, VR GO 4.0 has not changed from the previous version, but its stuffing has become more powerful.Image source: ZotacIn the basis of VR GO 4.0 offers a mobile Intel Core i7-11800H generation Tiger Lake processor.
For graphics processing here is responsible professional gas pedal NVIDIA RTX A4500 with 7168 CUDA cores and 20 GB of memory GDDR6.
The previous version of the device was equipped with a Core i7-9750H chip and GeForce RTX 2070 graphics.On the one hand, it may seem a strange choice in favor of not quite a gaming graphics card.
But the NVIDIA RTX A4500 is far more powerful than any entry-level gaming gas pedal.
For example, it has 1024 more CUDA cores than the GeForce RTX 3070 Ti gaming model.
At the same time, the NVIDIA RTX A4500 consumes 200 watts of power.
For comparison, for the same GeForce RTX 3080 the claimed power consumption is 350W.
For VR GO 4.0, the power consumption level is very important for autonomy, because the backpack computer runs on battery.The novelty offers 16 GB of DDR4 RAM.
If desired, you can install up to 32 GB of memory.
Moreover there is an opportunity to install an NVMe SSD in M.2 format and a 2.5\" SSD or a SATA III hard drive.
The set of external connectors consists of four USB 3.1 Type-A, one USB 3.1 Type-C, two USB 3.0, two DisplayPort and one HDMI.
There are also a pair of 3.5mm audio outputs and an SD card reader.
In standalone mode, the Zotac VR GO 4.0 is powered by a dual 86.4Wh hot-swappable battery.
The company did not provide information about the VR GO 4.0's release date or cost.
The previous version of the hiking computer was offered closer to $2,000.
Given the use of the professional NVIDIA RTX A4500 as part of the new generation of the device, its price could be even higher.

DARPA has ordered VR glasses for U.S.military medics

The American agency DARPA, known for its defense contracts, commissioned one of the leading developers with whom the agency cooperates, to invent and present a design of augmented reality glasses with artificial intelligence support under the working name \"MagicAI\".advertisementThese glasses will be profiled for military doctors, who can use them effectively help the wounded on the battlefield.
According to the Americans, their military doctors are good specialists, but generalists.
The augmented reality system in the new glasses will teach them how to perform more than 50 different medical operations and procedures in the field.
The \"MagicAI\" augmented reality goggles are ordinary VR glasses that are equipped with a set of sensors integrated with an artificial intelligence system that helps the doctor monitor what is happening around him on the battlefield.The \"doctor glasses\" AI gives the military doctor advice on how to proceed.
Contractors explained that the delivery to the army of such a device will be possible only after the augmented reality glasses will be sent to an in-depth machine learning course.
In the course of such training it is expected to instill in the new glasses the skills of medical care on the basis of a specialized database of military doctors collected during most conflicts.
This database consists of two and a half thousand videos and about 50 million images.It is believed that once this model goes to the troops, it will become a kind of \"prompter\" for military medics, who will receive voice prompts and at any time can refer to the video technique for even the most complex operations.The device will not only help doctors navigate the battlefield, but also offer them different treatment plans for patients, indicating the specific time of procedures and the required doses of medication.For the post accrued in
