AMD unveils next-gen AI chips as it takes on Nvidia: 'For the first time, we...' CEO Lisa Su says
AMD
has unveiled details about its
Instinct MI400 series
, the company's next generation of AI chips set to ship next year. CEO Lisa Su presented the chips at a launch event in San Jose, California, emphasising their design for "rack-scale" systems crucial for powering the massive AI computations of today and tomorrow. Su also claimed that AMD's MI355X can outperform
Nvidia
's Blackwell chips.
The MI400 series chips are designed to be assembled into a full server rack, dubbed Helios, which AMD described as a unified system capable of tying thousands of chips together, as per a report by CNBC.
"For the first time, we architected every part of the rack as a unified system," Su explained, highlighting Helios as "really a rack that functions like a single, massive compute engine."
OpenAI CEO Sam Altman endorses AMD chips
A significant endorsement came from OpenAI CEO Sam Altman, who appeared on stage with Su. Altman expressed confidence in the new chips
"When you first started telling me about the specs, I was like, there's no way, that just sounds totally crazy. It's gonna be an amazing thing," said Altman, whose company is a customer of Nvidia chips. OpenAI also confirmed it will be integrating the AMD chips.
What is different in AMD's newest AI chips
This "rack-scale" approach is vital for hyperscale AI clusters that span entire data centers, catering to the enormous power demands of cloud providers and developers of large language models, the report said. Su directly compared Helios to Nvidia's upcoming Vera Rubin racks, signaling AMD's intent to directly challenge its main rival.
AMD's rack-scale technology aims to put its latest chips squarely in competition with Nvidia's Blackwell chips, which already offer configurations integrating 72 graphics-processing units. Nvidia currently holds a near-monopoly in the market for big data center GPUs, partly due to its early lead in developing essential AI software like CUDA.
OpenAI, notably a significant Nvidia customer, has been providing feedback to AMD on its MI400 roadmap. AMD is positioning the MI400 chips, along with this year's MI355X chips, as a more cost-effective alternative to Nvidia's offerings.
Su also claimed that AMD's MI355X can outperform Nvidia's Blackwell chips, despite Nvidia's proprietary CUDA software advantage, saying that AMD's "really strong hardware" and the "tremendous progress" made by open software frameworks.

India to get new powerful super fighter jet which will destroy China, Pakistan within minutes, not US F-35, it's dangerous because...
Sukhoi Su-57 fighter jet- File image Sukhoi Su-57 fighter jet: In a significant development in India-Russia defence sector, Russia has reportedly offered India the export variant of its fifth-generation fighter jet, the Su‑57E. Additionally, Russia has also helped India with providing full source-code access, deep localization, and licensed production rights of the fighter jet. Here are all the details you need to know about the Russia-India Su-57E deal, which is bad news for Pakistan, China and the US. As per media reports, India has requested Russia to integrate indigenous systems like GaN-based AESA radars (e.g., Uttam) and mission computers in the Russian Su-57E fighter jet as a part of the deal, but the acceptance is under consideration. About Sukhoi Su-57 fighter jet The Sukhoi Su-57 is a twin-engine fifth generation stealth multirole fighter aircraft developed by Sukhoi. The Su-57E deal is very significant for India as India's indigenous AMCA program would need ateast a decade to produce the 5th generation fighter jet. Readers should note that US also reportedly offered its F-35 aircraft but India is likely to buy the Russian jet. India's 5th-generation stealth fighter jet gets key clearance In a major push towards Atmanirbharta (self-reliance), Defence Minister Rajnath Singh approved the Execution Model for the Advanced Medium Combat Aircraft (AMCA) programme on Tuesday. The project will be helmed by the Aeronautical Development Agency (ADA) of the Defence Research and Development Organisation (DRDO), said the Defence Ministry in a press release. India's answer to fifth-generation air power The AMCA, widely seen as India's answer to fifth-generation air power, will give a major boost to achieving 'Atmanirbharata' in the defence sector and will become a hallmark of India's growing defence capabilities. Being the fifth-generation stealth multirole fighter equipped with cutting-edge technology, it will be suited for all-weather operation. Designed with low radar cross-section and supercruise capability, the AMCA is seen as the successor to the frontline Sukhoi Su-30MKI fighter jets. Some reports suggest that its mass production is likely to commence by 2035. (With inputs from agencies)

Iran-Israel war escalation to impact India' s trade with West Asia, say experts
Any further escalation of the ongoing war between Iran and Israel will have wider implications for India 's trade with West Asian countries, including Iraq, Jordan, Lebanon, Syria, and Yemen, say experts. They said that the war has already started impacting India's exports to Iran and Israel. The US attacked three sites in Iran early Sunday, inserting itself into Israel's war aimed at destroying the country's nuclear programme in a risky gambit to weaken a longtime foe that prompted fears of a wider regional conflict as Tehran accused Washington of launching "a dangerous war". by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Many Are Watching Tariffs - Few Are Watching What Nvidia Just Launched Seeking Alpha Read Now Undo "We are in for big trouble now because of this war. It will have a cascading effect on India's trade with West Asian countries," Mumbai-based exporter and founder chairman of Technocraft Industries India Sharad Kumar Saraf said. Saraf said that his company is also holding back consignments to both these countries. Technocraft Industries manufactures drum closures, nylon and plastic plugs, capseal closures, and clamps. Live Events "There will be a cascading effect of this war," he added. Another exporter said that the Indian traders community is already reeling under the impact of the Israel-Hamas conflict and involvement of Yemen-backed Houthis' attack on shipping vessels in the Red Sea. Due to that, shipping lines from India were taking consignments from the Cape of Good Hope, encircling the African continent. Now, because of the Iran-Israel war, another key trading route - the Strait of Hormuz - is getting affected. "This route will hit the movement of oil tankers. I have a feeling that oil tankers will find new routes but that will push crude oil prices. It will have implications on inflation as crude oil prices are the mother of all prices," Saraf said. Think tank Global Trade Research Initiative (GTRI) said that a wider regional escalation could threaten India's much larger trade with the broader West Asian region, including Iraq, Jordan, Lebanon, Syria, and Yemen, where Indian exports total USD 8.6 billion and imports stand at USD 33.1 billion. "Any disruption to shipping lanes, port access, or financial systems in this corridor would severely impact India's trade flows, inflate freight and insurance costs, and introduce fresh supply chain risks for Indian businesses," GTRI Founder Ajay Srivastava said. India's exports to Iran stood at USD 1.24 billion in FY2025, with key items including Basmati rice (USD 753.2 million), banana (USD 53.2 million), soya meal (USD 70.6 million), Bengal gram (USD 27.9 million), and tea (USD 25.5 million). Imports stood at USD 441.8 billion last fiscal. With Israel, India's exports stood at USD 2.1 billion and USD 1.6 billion in imports in 2024-25. He said that the ongoing US-Israel strikes on Iran and the threat of wider conflict could significantly disrupt this trade. Payment channels already strained by US sanctions may face further blockages, while heightened shipping risks in the Gulf could drive up insurance costs and delay shipments. "Perishable exports like rice, bananas, and tea are especially vulnerable. A prolonged conflict could dampen Iranian demand and squeeze Indian exporters, particularly in the agricultural sector," Srivastava said. GTRI said that a key concern is the potential disruption to the Strait of Hormuz, through which roughly 60-65 per cent of India's crude imports transit. "Any blockade or military escalation in this vital maritime corridor would severely impact India's energy security, drive up oil prices, and trigger inflationary pressures at home," it added. India enjoys deep historical, cultural, and economic ties with Iran, once a major crude oil supplier and views Iran's Chabahar Port as a strategic gateway to Afghanistan and Central Asia, providing crucial connectivity while bypassing Pakistan. Yet India also maintains robust relations with the US, Israel, and Gulf Arab states, each now directly or indirectly involved in the unfolding confrontation, Srivastava said. India's crude oil and half of its LNG imports pass through the Strait of Hormuz, which Iran has threatened to close. This narrow waterway, only 21 miles wide at its narrowest point, handles nearly a fifth of global oil trade and is indispensable to India, which depends on imports for over 80 per cent of its energy needs. The Strait of Hormuz, which lies between Iran to the north and Oman and the United Arab Emirates to the south, serves as the main route for oil exports from Saudi Arabia, Iran, Iraq, Kuwait, and the UAE. Many liquefied natural gas (LNG) shipments, especially from Qatar, also pass through the strait. According to the Delhi-based economic think tank, any closure or military disruption in the Strait of Hormuz would sharply increase oil prices, shipping costs, and insurance premiums, triggering inflation, pressuring the rupee, and complicating India's fiscal management. The present conflict that began with an attack on Israel on October 7, 2023, has brought cargo movement through Red Sea routes to a halt due to attacks by Houthi rebels on commercial shipping. Last year, the situation around the Bab-el-Mandeb Strait, a crucial shipping route connecting the Red Sea and the Mediterranean Sea to the Indian Ocean, escalated due to attacks by Yemen-based Houthi militants. Around 80 per cent of India's merchandise trade with Europe passes through the Red Sea, and substantial trade with the US also takes this route. Both these geographies account for 34 per cent of the country's total exports. The Red Sea Strait is vital for 30 per cent of global container traffic and 12 per cent of world trade. Based on the tariff war impact, the World Trade Organisation ( WTO ) has already said that global trade will contract 0.2 per cent in 2025 as against the earlier projection of 2.7 per cent expansion. India's overall exports had grown 6 per cent on year to USD 825 billion in 2024-25. This year it is expected to cross USD 900 billion. Snapping the two-month rising trend, India's exports declined by 2.17 per cent year-on-year to USD 38.73 billion in May due to a fall in petroleum goods' shipments.
