AMD vs Intel in the CPU market battle

The competition between AMD and Intel remains intense, despite Intel’s larger market share. In recent years, AMD has emerged as the preferred choice for gamers, often topping sales charts, including Amazon’s CPU best-sellers list.

Just yesterday, AMD dominated the top 15 spots instead of Intel. Surprisingly, the top processor was AMD’s Ryzen 7 9800X3D, a high-end gaming chip, priced at $480, despite its occasional stock shortages.

The top 15 list featured a mix of older and newer AMD processors, such as the Ryzen 5 5500 and Ryzen 5 5600X, indicating that AMD has successfully kept older hardware relevant and in demand.

However, today’s best-seller list paints a slightly different picture, as Intel has managed to secure several spots, with older models like the Alder Lake chips offering more affordable alternatives to current AMD processors.

Interestingly, Intel’s latest Arrow Lake processors did not make it to the top 50 best-sellers on Amazon. This suggests that many customers prefer the more affordable Intel options or turn to AMD, which has shifted the market dynamics significantly in recent years.

MIT advances scalable quantum computing networks

MIT researchers have developed a breakthrough quantum interconnect device that could significantly advance quantum computing by enabling direct communication between multiple quantum processors.

Unlike point-to-point architectures, which suffer from compounded error rates, their new ‘all-to-all’ communication system allows superconducting quantum processors to exchange quantum information efficiently using microwave photons.

By successfully demonstrating remote entanglement between two quantum processors, the researchers have taken a crucial step toward building large-scale quantum computing networks.

Their method involves using superconducting wires to shuttle photons, allowing quantum processors to remain entangled even when physically separate. However, this advancement paves the way for scalable quantum computing with higher flexibility and reduced error rates.

To maximise efficiency, the team employed reinforcement learning algorithms to optimise photon absorption, achieving over 60% absorption efficiency—enough to confirm successful entanglement.

Future improvements may involve refining photon pathways and integrating modules in 3D to further enhance performance. The research, supported by multiple US agencies and AWS, brings quantum computing closer to practical, large-scale implementation.

Data centre surge exposes vulnerabilities in the US grid

A recent incident in Data Center Alley, a region outside Washington DC housing over 200 data centres, exposed a new vulnerability in the US power grid.

Last summer, 60 data centres unexpectedly disconnected from the grid and switched to on-site generators, causing a surge in excess electricity. However, this triggered the need for grid operators to scale back power output to avoid cascading outages.

The disconnection event, caused by a failed surge protector, forced regulators to address the growing risk of power imbalances due to the rapid expansion of data centres, especially those involved in AI and crypto mining.

As these centres consume increasing amounts of energy, grid operators face new challenges in maintaining stability.

Federal regulators like the North American Electric Reliability Corporation (NERC) are now studying the impact of such events and the risks posed by unannounced data centre disconnections.

The power consumption of data centres has tripled over the last decade and is projected to continue rising, prompting calls for updated reliability standards.

Industry stakeholders, including major tech companies, have expressed concerns about the potential costs and risks of requiring data centres to remain connected during voltage fluctuations.

With the growing presence of large data users, grid operators face a tough balancing act to ensure power stability while accommodating the demands of the data centre industry.

Ofcom backs broadband competition to expand full-fibre coverage

Britain should maintain competition in the broadband market to boost full-fibre coverage to 96% of premises by 2027 while capping prices on slower-speed services, UK telecoms regulator Ofcom announced on Thursday.

The cap would limit what BT’s Openreach can charge for connections up to 80Mbit/s, an increase from the current 40Mbit/s limit.

Ofcom’s previous measures, including encouraging new providers to use Openreach’s infrastructure, have helped increase full-fibre coverage from under 25% to nearly 70% of homes.

It now proposes keeping high-speed broadband prices free from regulation until 2031 while ensuring affordability for those relying on older copper-fibre connections.

In rural areas where commercial networks are less viable, Ofcom plans to support Openreach in expanding full-fibre access. The regulator’s consultation on these proposals will run until June 12, with final decisions expected in March 2026. BT shares rose 0.5% following the announcement.

Nvidia holds back on optical technology for GPUs

Nvidia’s CEO, Jensen Huang, has stated that a promising new chip technology, co-packaged optics, is not yet reliable enough for use in the company’s flagship GPUs.

The technology, which uses laser beams to transfer data via fiber optic cables instead of traditional copper, is more energy-efficient and faster.

However, Huang emphasized that copper connections remain ‘orders of magnitude’ more reliable than today’s optical alternatives, making them the preferred choice for now.

Speaking at Nvidia’s annual developer conference in San Jose, Huang announced that the company will use co-packaged optics in two upcoming networking chips designed for server switches, increasing their energy efficiency by three and a half times.

These switch chips will be released later this year and into 2026, marking a gradual technological step forward. However, Huang clarified that Nvidia currently has no plans to implement optical connections between GPUs, as reliability remains a key priority for its AI-focused customers like OpenAI and Oracle.

Silicon Valley startups such as Ayar Labs, Lightmatter, and Celestial AI have invested heavily in co-packaged optics, seeing it as essential for building more powerful AI systems. Nvidia itself has backed some of these ventures, despite Huang’s cautious approach.

While optical connections could eventually help AI models process complex tasks more efficiently, Nvidia is prioritizing proven technology for its near-term roadmap, ensuring stability in an industry preparing to invest hundreds of billions in AI infrastructure.
