Faster broadband is on the way, and it won’t require network providers to overhaul their infrastructure.

nbn, the largest wholesale broadband provider in Australia, used Nokia’s Lightspan MF fiber platform, to deliver 10G, 25G, 50G and 100G broadband speeds over its existing fiber network. Nokia’s Lightspan delivers next-generation Passive Optical Network (PON) at scale.

PON is a type of fiber-optic network that combines point-to-multipoint fiber architecture with communications networking. The technology works by using a single fiber-optic connection that divides into many distinct fibers, allowing one line to serve multiple users. This is achieved through both active and passive splitters, hence the name. PON technology boosts the efficiency of a network because it reduces the number of active switching devices used. Furthermore, it requires less power and supports greater distances between users and their service providers.

A game-changer

There are a number of different types of PON technologies, including Gigabit Passive Optical Network (GPON), Ethernet Passive Optical Network (EPON), and next-generation PON like XG-PON (10 Gigabit PON) and NG-PON2 (40 Gigabit PON). Nokia’s Lightspan supports a full range of PON options.

Geert Heyninck, vice president of broadband networks at Nokia, said: “There is a huge opportunity for operators to leverage their existing fiber broadband networks to efficiently add advanced services which goes way beyond consumer services. Think enterprise, mobile backhaul, Smart City, industry 4.0. It’s important for service providers to have choices to match the right speed and cost points to meet the different use cases and market requirements they may have. As the industry’s first and only solution capable of supporting the full range of PON technologies from 10G to 25G, 50G, and even 100G, we can give operators the freedom and flexibility they need to meet their business needs while also helping to optimize network performance and reduce costs.”

The trial highlighted the ease with which operators can upgrade the 10G PON to a symmetrical 25G PON and subsequently to 50G PON or 100G, using identical passive and active fiber components. This network evolution could be game-changing in delivering an enhanced digital experience for users, but there’s currently no word on when we can expect it to become widely available.

Nvidia’s fastest AI chip ever could cost a rather reasonable $40,000 — but chances that you will actually be able to buy one on its own are very, very low and for a good reason

[ad_1]

In a recent interview with CNBC’s Jim Cramer, Nvidia CEO Jensen Huang shared details about the company’s upcoming Blackwell chip which cost $10 billion in research and development to create.

The new GPU, which is built on a custom 4NP TSMC process and packs a total of 208 billion transistors (104 billion per die), with 192GB of HMB3e memory and 8TB/s of memory bandwidth, involved the creation of new technology because what the company was trying to achieve “went beyond the limits of physics,” Huang said.

During the chat, Huang also revealed that the fist-sized Blackwell chip will sell for “between $30,000 and $40,000”. That’s similar in price to the H100 which analysts say cost between $25,000 and $40,000 per chip when demand was at its peak.

A big markup

According to estimates by investment services firm Raymond James (via @firstadopter), Nvidia B200s will cost Nvidia in excess of $6,000 to make, compared with the estimated $3320 production costs of the H100.

The actual final selling price of the GPU will vary depending on whether it’s bought directly from Nvidia or through a third party seller, but customers aren’t likely to be purchasing just the chips.

Nvidia has already unveiled three variations of its Blackwell AI accelerator with different memory configurations — B100, B200, and the GB200 which brings together two Nvidia B200 Tensor Core GPUs and a Grace CPU. Nvidia’s strategy, however, is geared towards selling million dollar AI supercomputers like the multi-node, liquid-cooled NVIDIA GB200 NVL72 rack-scale system, DGX B200 servers with eight Blackwell GPUs, or DGX B200 SuperPODs.

‘The fastest AI chip in the world’: Gigantic AI CPU has almost one million cores — Cerebras has Nvidia firmily in its sights as it unveils the WSE-3, a chip that can train AI models with 24 trillion parameters

Cerebras Systems has unveiled its Wafer Scale Engine 3 (WSE-3), dubbed the “fastest AI chip in the world.”

The WSE-3, which powers the Cerebras CS-3 AI supercomputer, reportedly offers twice the performance of its predecessor, the WSE-2, at the same power consumption and price.

The chip is capable of training AI models with up to 24 trillion parameters, a significant leap from previous models.

CS-3 supercomputer

The WSE-3 is built on a 5nm TSMC process and features 44GB on-chip SRAM. It boasts four trillion transistors and 900,000 AI-optimized compute cores, delivering a peak AI performance of 125 petaflops – that’s the theoretical equivalent to about 62 Nvidia H100 GPUs.

The CS-3 supercomputer, powered by the WSE-3, is designed to train next-generation AI models that are 10 times larger than GPT-4 and Gemini. With a memory system of up to 1.2 petabytes, it can reportedly store 24 trillion parameter models in a single logical memory space, simplifying training workflow and boosting developer productivity.

Cerebras says its CS-3 supercomputer is optimized for both enterprise and hyperscale needs, and it offers superior power efficiency and software simplicity, requiring 97% less code than GPUs for large language models (LLMs).

Cerebras CEO and co-founder, Andrew Feldman, said, “WSE-3 is the fastest AI chip in the world, purpose-built for the latest cutting-edge AI work, from mixture of experts to 24 trillion parameter models. We are thrilled for bring WSE-3 and CS-3 to market to help solve today’s biggest AI challenges.”

The company says it already has a backlog of orders for the CS-3 across enterprise, government, and international clouds. The CS-3 will also play a significant role in the strategic partnership between Cerebras and G42, which has already delivered 8 exaFLOPs of AI supercomputer performance via Condor Galaxy 1 and 2. A third installation, Condor Galaxy 3, is currently under construction and will be built with 64 CS-3 systems, producing 8 exaFLOPs of AI compute.

Rimac Nevera is the world’s fastest car in reverse

Rimac Nevera

Rimac already holds a number of world records for their Rimac Nevera supercar and now they have set another one. The Rimac Nevera is now the world’s fastest car in reverse and the video below shows the record being set.

The car managed an impressive top speed of 171.34 miles per hour or 2754.74 km/h in reverse, this is the same speed that was set by the Lamborghini Miura in 1969, although that car was going forward and not backward.

Witnessed by Guinness World Records and verified using data measured by Dewesoft, the Nevera now officially holds the GUINNESS WORLD RECORDS title for the fastest speed in reverse. Hosted at the Automotive Testing Papenburg facility in Germany, the Nevera returned to the place where – earlier this year – it had broken more than 20 acceleration and braking records in a single day, as well as the site of its record-breaking top speed run to 256mph (412km/h). Finished in the Time Attack Edition livery worn during earlier record-breaking runs – available to just 12 customers globally – the Nevera was driven to a top speed of 171.34mph (275.74km/h).

Unlike an internal combustion engine car, or even some electric cars, the drivetrain of the Nevera has no gears – the four individual motors either go backwards or forwards but it’s always one relentless wall of acceleration right the way from standstill. That means that the same powertrain capable of delivering 0-100mph in 3.21 seconds or 0-200mph in just under 11 seconds forwards could also deliver similar earth-shattering performance travelling backwards.
