SANTA CLARA, California - Sept 24 (Reuters) - The
computing chips that power artificial intelligence consume a lot
of electricity. On Wednesday, the world's biggest manufacturer
of those chips showed off a new strategy to make them more
energy efficient: Using AI-powered software to design them.
At a conference in Silicon Valley, Taiwan Semiconductor
Manufacturing Co ( TSM ), the contract manufacturer that
fabricates chips for Nvidia ( NVDA ), showed off a range of ways
that it is hoping to boost the energy efficiency of AI computing
chips by about 10 times.
Nvidia's ( NVDA ) current flagship AI servers, for example, can
consume as much as 1,200 watts during demanding tasks, which
would be the equivalent of the power used by 1,000 U.S. homes if
run continuously.
The gains TSMC is hoping to achieve come from a new
generation of chip designs in which multiple "chiplets" -
smaller pieces of full computing chips - using different
technologies are packaged together to make one computing
package.
But to make use of those technologies, the firms that design
chips are increasingly relying on AI-powered software from
providers such as Cadence Design Systems ( CDNS ) and Synopsys ( SNPS )
, both of which rolled out new products on Wednesday
that had been developed in close coordination with TSMC.
For some of the complex tasks in designing chips, the tools
from TSMC's software partners found better solutions than TSMC's
own human engineers - and did so much faster.
"That helps to max out TSMC technology's capability, and we
find this is very useful," Jim Chang, deputy director at TSMC
for its 3DIC Methodology Group, said during a presentation
describing the findings. "This thing runs five minutes while our
designer needs to work for two days."
The current way of manufacturing chips is hitting limits, such
as the ability to move data on and off chips using electrical
connections. New technologies, such as moving information
between chips with optical connections, need to be made reliable
enough to use in massive data centers, said Kaushik
Veeraraghavan, an engineer in Meta Platforms' infrastructure
group who gave a keynote address.
"Really, this is not an engineering problem," Veeraraghavan
said. "It's a fundamental physical problem."
