Most learn – Mediatek processor, Racks not chips, Google capex ⋆ Electronics Weekly

Contemplating solely the information articles written within the final week, the preferred ones on the positioning cowl Google’s ballooning datacentre capex, Imec demonstrating 22nm pitch on a single-print high-NA step and a semiconductor that adjustments its properties in response to mild.

And there’s additionally a narrative about worth in datacentres shifting from the chip to the rack, and Mediatek launching its 2nm Dimensity 9600 Professional with the goal of lowering reminiscence use…

As all the time, let’s take them in reverse order, in response to Google Analytics:

5. Google unworried by $200bn datacentre capex
A Google server pays for its price in two years and, if it’s operating on Google chips, pays for itself in a yr, in response to Google Cloud CEO Thomas Kurian. “The dimensions of our accelerator enterprise, our TPU enterprise, is greater than twice that of the next-largest hyperscaler,” Kurian, informed a Goldman Sachs convention. Google Cloud had Q2 revenues of $24.77 billion.

4. Imec demoes 22nm pitch on single-print high-NA step
Imec demonstrates the feasibility of patterning tight-pitch random logic buildings after a CAR-based single-print Excessive NA EUV lithography step. Logic buildings embody strains/areas all the way down to 22nm pitch, and vias at 28nm center-to-center distance. This reveals that CAR resist expertise can be utilized for the Excessive NA EUV single patterning of a number of layers of the A14/A10 logic expertise nodes.

3. Semiconductor programmed by mild
Researchers at Princeton create a semiconductor that may be a few molecules thick and might repeatedly change its properties in response to mild. The researchers have created a uniform piece of the semiconductor that’s 1-inch sq.. Subsequent, they’re working to create a circuit, a elementary constructing block for any complicated digital machine.

2. Datacentre efficiency now offered by the rack not the chip
The worth in datacentres is shifting from the chip to the rack, says Yole, with hyperscalers and AI labs co-designing their very own AI asics and with superior packaging, HBM4, co-packaged optics and energy (1MW racks, 800V, liquid cooling) setting the route. “AI has turned the datacentre right into a full-system drawback,” says Yole’s Eric Mounier, “efficiency is now offered by the rack, not the chip…”

1. Mediatek processor goals to go mild on reminiscence
Mediatek launches the 2nm Dimensity 9600 Professional with the goal of lowering reminiscence utilization at a time of excessive reminiscence price. “We’re working carefully with a number of clients on applied sciences that may assist cut back the reminiscence footprint whereas attaining the identical computing efficiency, and due to this fact assist alleviate among the strain from rising costs,” says Mediatek svp and gm for wi-fi comms, JC Hsu.
