The Globe and Mail reports in its Wednesday edition that Advanced Micro Devices forecast fourth-quarter revenue above Wall Street estimates on Tuesday, buoyed by strong demand for its chips as its multibillion-dollar effort to challenge Nvidias dominance of the AI semiconductor market gains momentum. A Reuters dispatch to The Globe says shares of the company jumped more than 8 per cent in extended trading. AMD, which nearly doubled its data-centre revenue in the third quarter, is benefiting as a shift in artificial-intelligence workloads toward running models in real-world applications drives demand for its graphics processing units and central processors. This has enabled AMD to capture market share from rival Intel, which last week forecast quarterly revenue well below estimates and triggered a global sell-off in chip stocks. "The AMD numbers provide a greatly needed boost both for AI infrastructure and even, to a smaller degree, the PC market," said Bob O'Donnell, chief analyst at TECHnalysis Research. AMD expects Q4 revenue of about $17-billion (U.S.), plus or minus 3 per cent, above analysts' average estimate of $16.23-billion (U.S.). AMD has stepped up AI product rollouts, moving beyond stand-alone chips.
