The United States “will not tolerate” a de facto Chinese ban on the purchase of Micron Technology memory chips by Chinese companies and is working closely with allies to combat such “economic coercion,” U.S. Commerce Secretary Gina Raimondo said.

Raimondo told a press conference following a meeting of trade ministers as part of US-led Indo-Pacific Economic Plan talks that the US “strongly opposes” China’s move against Micron.

These actions are targeted at one American company without any factual basis and we see this as simple and simple economic coercion and we will not tolerate it and do not think that this initiative will be successful.

The Cyberspace Administration of China (CAC) said on May 21 that the products of US memory chip maker Micron have not passed security checks. Therefore, key infrastructure operators are prohibited from purchasing products from this company.

Raimondo added that “the move comes a day after the leaders of the G7 industrialized democracies agreed to new initiatives to counter Chinese economic coercion.”

As we spoke at the G7, and as we have repeatedly stated, we are working closely with partners who are tackling this particular issue and all the issues related to China’s non-market practices.

Honor today introduced the Honor 90 Pro smartphone, the main feature of which was the screen. It supports 3840Hz PWM and has been certified by TUV Rheinland to be flicker-free, which even people with very sensitive eyes will not notice. Yesterday we clearly showed that in this regard, it turned out to be Galaxy S23 Ultra and iPhone 14 Pro.

According to the international standard IEEE Std1789-2015, when the screen flicker frequency exceeds 3125Hz, stroboscopic flicker does not pose a danger to human eyes. The current PWM frequencies of 2160 Hz, 1920 Hz and 1440 Hz, which are widely used in flagships, are still noticeable.

The Honor 90 series screen has a contrast ratio of 5,000,000:1, supports 1.07 billion colors and 10-bit color depth. The Honor 90 Pro uses a 6.78-inch screen.

Honor 90 Pro is equipped with a 200-megapixel 1/1.4-inch optical format main camera that supports 16-pixel binning with an equivalent pixel size of 2.24 microns. It also features a 12MP ultra-wide-angle macro lens and a 32MP telephoto portrait lens with 1x, 2x and 2.5x modes.

On the front of the Honor 90 Pro is a 50MP portrait dual camera that supports 100° ultra wide-angle shooting. The minimum focusing distance can be as short as 2.5 cm.

The smartphone received a Qualcomm Snapdragon 8 Plus Gen 1 single-chip system, as well as a 5000 mAh battery that supports 90-watt charging.

Honor 90 received a 6.7-inch screen, Snapdragon 7 Gen 1, a 200-megapixel camera, the same battery and 66-watt charging.

Nvidia today announced a new class of high-memory AI-based supercomputers, the Nvidia DGX supercomputer powered by Nvidia GH200 Grace Hopper superchips and Nvidia NVLink switching system, designed to develop new generative AI applications, recommender systems, and big data processing.

The Nvidia DGX GH200 uses NVLink Switch System technology to combine 256 GH200 superchips, allowing them to operate as a single GPU. This delivers 1 EFLOPs of performance and 144TB of total memory—nearly 500 times more memory than the previous generation Nvidia DGX A100 introduced in 2020.

“Generative AI, large language models, and recommender systems are the digital engines of today’s economy,” said Jensen Huang, founder and CEO of Nvidia. “The DGX GH200 AI Supercomputer combines Nvidia’s most advanced accelerated computing and networking technologies to push the boundaries of AI.”

The GH200 superchips eliminate the need for traditional PCIe CPU-GPU connectivity by combining an Arm-based Nvidia Grace CPU with an Nvidia H100 Tensor Core GPU in a single package using Nvidia’s NVLink-C2C chip. This increases the throughput between GPU and CPU by 7x compared to the latest PCIe technology, reduces interconnect power consumption by more than 5x, and provides a 600GB Hopper architecture GPU building block for DGX GH200 supercomputers.

The DGX GH200 is the first supercomputer to combine Grace Hopper superchips with Nvidia’s NVLink switching system, which allows all the GPUs in the DGX GH200 system to work together as one. The previous generation system had only eight GPUs, which could be combined with NVLink into a single GPU without sacrificing performance.

The DGX GH200 architecture delivers 48 times the bandwidth of NVLink than the previous generation, delivering the power of a massive AI supercomputer with the ease of programming a single GPU.

Nvidia is building its own AI supercomputer based on the DGX GH200 to power its research and development teams. The supercomputer, called Nvidia Helios, will feature four DGX GH200 systems. Each will be connected to an Nvidia Quantum-2 InfiniBand network to increase data throughput for training large AI models. Helios will include 1,024 Grace Hopper superchips and is expected to be launched by the end of the year.
