Nvidia has created an exclusive H800 accelerator for China, slowing down the top H100
Nvidia has unveiled its fastest and most sophisticated graphics accelerator, the H100 NVL, with 188 GB of memory for training language models, but such a product cannot be shipped to China due to US sanctions. Therefore, Nvidia created a separate accelerator for the Chinese market – H800.
The H800 is a slowed down version of the regular H100 (not the H100 NVL). The fact is that US regulations were introduced last year to prevent many manufacturers from importing and exporting goods to China. Therefore, Nvidia developed a legal version of the H100, intended exclusively for export to Chinese companies.
It is known that the H800 has halved the data transfer rate, and it is not very clear what speed we are talking about. It probably means the bandwidth of the interface. Whether there are any other restrictions is unknown. In any case, the H800 should be a very capable product.

Microsoft has released a major Windows 11 update for all users – installation optional
Microsoft has made a major update to the Windows 11 operating system, also known as Moment 5, available to all users as an optional update KB5035942.
Users can optionally install KB5035942 through Windows Update. Previously, the company allowed enthusiasts to manually activate new features from an update. Moment 5 is now available to everyone directly from Windows Update.
Windows 11 Moment 5 brings quite a lot of innovations. Among them are an improved Copilot AI assistant function with new plugins and skills, improved “Photos” with a smart “eraser”, an improved Clipchamp video editor (possibly removing “awkward pauses”), closer integration with Android smartphones (can now be used in as a webcam), and much more.

Space meteorologists predicted a new geomagnetic storm: the Sun is approaching maximum activity
Space meteorologists have issued a forecast for this week warning of a possible geomagnetic storm caused by the release of plasma from a solar flare. This could affect radio transmissions on Earth and contribute to the observation of the “northern lights.”
According to an alert issued March 23 by NOAA’s Space Weather Prediction Center in Boulder, Colorado, the public has no reason to be concerned.
Mainly, solar storms can disrupt high-frequency radio transmissions, such as communications between aircraft and remote towers. Jonathan Lash, a forecaster at the center, noted that many commercial aircraft can use satellite communications as a backup option.
Satellite operators may also have problems tracking their spacecraft, and the power grid may detect induced current in its lines.
“For the general public in high latitudes, with clear skies, this will be a great opportunity to see the ‘northern lights,'” Lash said.
Every 11 years, the Sun’s magnetic field changes and its north and south poles switch places. During this cycle, solar activity also changes and is now approaching its peak, which is called solar maximum.
During solar maximum, geomagnetic storms like the one observed last Sunday can occur on Earth several times a year, according to Lash. During periods of solar minimum, several years may pass between storms.
Last December, the largest solar flare in recent years disrupted radio communications.

BYD cuts prices on 100 models to beat Toyota and Volkswagen
BYD is going to beat Toyota and Volkswagen by offering modern cars at very low prices. According to Bloomberg, the Chinese automaker has reduced prices on more than 100 of its electric and hybrid models.
For example, BYD’s new generation-changing Seagull hatchback now costs less than $10,000, while the manufacturer’s best-selling electric sedan, the Qin Plus, costs less than $11,000.
BYD announced the beginning of an era called “electricity is cheaper than oil”, when hybrid and pure electric models become as affordable as traditional models with internal combustion engines, or even cheaper.
In total, BYD has already relaunched more than 70 models with lower prices. According to Bloomberg, only the newest Yangwang supercar worth 233 thousand dollars has not fallen in price so far.
By lowering prices, BYD wants to convince drivers to ditch gasoline cars and switch to electric vehicles and hybrids. This aggressive pricing policy poses a real threat to Toyota, Volkswagen, Nissan and other manufacturers.
Previously, BYD Auto officially announced the production of its 7 millionth new energy vehicle, which turned out to be the Denza N7.
