Toasted golden, schmeared with insight. Top of the rack.
Summary
The article discusses RF (Radio Frequency) over fiber technology as a solution for improving data center efficiency, particularly for AI model training. It explains the concepts of 'scaling out' (linking more AI computers together) and 'scaling up' (packing more GPUs into each computer), and how these approaches require different physical connections. The article highlights how innovative radio-based connectivity solutions from startups could potentially outperform traditional copper cables in data centers, enabling faster data transfer rates for AI workloads.
Key quotes
· 5 pulledHow fast you can train gigantic new AI models boils down to two words: up and out.
In data-center terms, scaling out means increasing how many AI computers you can link together to tackle a big problem in chunks.
Scaling up, on the other hand, means jamming as many GPUs as possible into each of those computers, linking them so that they act like a single gigantic GPU.
The two domains rely on two different physical connections.
Point2's cables are made up of eight e-Tube fibers, each carrying more than 200 gigabits of data per second.
