Michael Frank, Fellow and Chief Architect at Arteris IP quoted in this new article in Semiconductor Engineering:
Have Processor Counts Stalled?
September 24th, 2020 - By Brian Bailey
Have chips reached a plateau for the number of processor cores they can effectively make use of? Possibly yes, until you change the programming model.
“The number of processors has stalled in platforms like PCs or portable devices,” says Michael Frank, fellow and system architect at Arteris IP. “This has less to do with Moore’s Law leveling out than the fact that it’s getting very hard, from a software point of view, to find enough work for more processors. Unless you have highly parallel workloads, it is really really hard to keep all these cores busy.”
