SEOUL, July 29 (Reuters) - South Korean chipmaker SK ​Hynix (000660.KS), opens new tab reported a more than sixfold ‌increase in quarterly operating profit to a record high on Wednesday, driven by robust demand for advanced ​memory chips as big technology firms ramped ​up spending on AI data centres.

The Nvidia (NVDA.O), opens new tab ⁠supplier reported an operating profit of 60.5 ​trillion won ($41.62 billion) for the April-June period, ​compared with 9.2 trillion won a year earlier. But it missed a 64 trillion won forecast by LSEG ​SmartEstimate, which is weighted toward analysts who ​are more consistently accurate.

"Driven by sustained demand growth from expanding ‌AI ⁠infrastructure investments, high-performance products for AI servers led price increases, enabling the company to surpass its previous record set in the prior ​quarter," SK ​Hynix said ⁠in a statement.

SK Hynix missed analysts' forecasts because its higher exposure to ​high-end memory chips used in AI ​data ⁠centres than rivals meant it benefited less from a stronger price rally in conventional memory ⁠chips.

The ​company said its quarterly revenue ​rose 257% to 79.3 trillion won.
