Samsung's new HBM3E memory technology hits 1.2TB/s — you can bet that it will power Nvidia's next AI monster GPU, the GH200

Samsung’s latest memory technology has hit staggering speeds of 9.8Gb/s – or 1.2TB/s – meaning it’s more than 50% faster than its predecessor. 

The HBM3E memory standard, nicknamed Shinebolt, is the latest in a series of high-performance memory units Samsung has developed for the age of cloud computing and increased demand for resources.

Shinebolt is a successor to Icebolt, which comes in varieties up to 32GB, can reach speeds of up to 6.4Gb/s. These chips were designed specifically to be used with the best GPUs out there in AI processing and LLMs, with the firm ramping up production this year as the emerging industry gathers momentum.

Powering the next generation of AI chips

HBM3E will inevitably find its way into the components developed by the likes of Nvidia, with every suggestion it can find its way into the GH200, nicknamed Grace Hopper, in light of a recent deal it struck.

High-bandwidth memory (HBM) is much faster and more energy efficient than conventional RAM, and uses 3D stacking technology which lets the layers of chips to be stacked on top of each other.

Samsung’s HBM3E stacks layers higher than in previous iterations through the use of non-conductive film (NCF) technology, which eliminates gaps between the layers in the chips. Thermal conductivity is maximized, and it can ultimately hit much higher speeds and efficiency as a result. 

The unit will power the next generation of AI applications, Samsung claims, as it’ll speed up AI training and inference in data centers and improve the total cost of ownership (TCO). 

Even more exciting is the prospect that it’ll be included in Nvidia’s next-gen AI chip, the H200. The two companies struck an agreement in September in which Samsung would supply the chipmaker with HBM3 memory units, according to the Korea Economic Daily, with Samsung set to supply roughly 30% of Nvidia’s memory by 2024. 

Should this partnership continue, there’s every possibility HBM3E components will become part of this deal once they enter mass production.

Garmin's new radar-equipped tail light will keep you safe on your e-bike

Garmin's Varia bike radars are some of the most popular pieces of cycling tech around – and now the company has delivered its first rearview radar to have been specially designed for some of the best e-Bikes .   Garmin's Varia range mounts to the back of your bike and broadcasts a radar signal behind you, so you can get visual and audible alerts when something's overtaking you. Even better, the new Varia eRTL615 plugs directly into most e-bikes, with no battery required. Because the catchily-named Varia eRTL615 is also a tail light, it'll also make sure you're visible to other vehicles too, promising to emit a flashing or solid light that's visible from up to a mile away in daylight. To connect Garmin's new radar tail light to your e-bike, you'll need to pick the right Garmin adapter cable (which isn't included). You can buy power cables compatible with Bosch, Shimano, or USB-A terminals or connections, with more info on those available on Garmin...

Revolution Software is using their own AI technology to remake Broken Sword

TechRadar Gaming is reporting live from Gamescom 2023 on the latest and greatest developments in gaming and hardware. Revolution Software announced at Gamescom 2023 that Broken Sword would be coming back, with Broken Sword - The Shadow of the Templars getting a full remake while a sixth title in the series is coming in the future too, under the title Broken Sword - Parzival’s Stone .  Speaking to TRG ahead of the announcement, Cecil talked about the studio’s plans for a Broken Sword remake and the sixth title in the series. Cecil is a larger-than-life character, who is able to talk about the studio’s plans with enthusiasm. It even carries a pocketful of stones to illustrate the plans for Parzival’s Stone , but he also talks about how Broken Sword - The Shadow of the Templars would be using AI to upscale.  Cecil wasn’t shy about the studio’s use of AI technology, but he gave a fairly robust explanation of why the game was using it. The AI technology will be used to upda...

Hackers steal passwords, emails from hookup websites

Two gay hookup websites have been breached with sensitive and personal user data stolen and sold online, new reports have claimed. The databases, which are now being sold on dark web forums, were taken from platforms called TruckerSucker, and CityJerks. They contain enough personally identifiable information to engage in identity theft , such as usernames and passwords, email addresses, profile pictures, sexual preferences, birth dates, postal addresses, IP addresses, and bios. The passwords are encrypted, but according to TechCrunch, the algorithm is “weak” and could be broken by a more persistent hacker. The silent treatment HaveIBeenPwned founder Troy Hunt, who was tipped off on the leak, described the incident as a “typical forum breach, albeit with super sensitive content.”  However the content includes more than just identity data, as there are also messages users exchanged, including arranging meetings and describing their sexual preferences.  In total, more than...
