SEOUL, Jan 8 (Reuters) - Samsung Electronics ( SSNLF )

estimated on Wednesday a 131% jump in fourth-quarter operating

profit from a year earlier but missed analyst estimates by a

large margin as it lagged behind rival SK Hynix ( HXSCF ) in

supplying high-end chips to Nvidia ( NVDA ).

The world's largest memory chip, smartphone and TV maker

estimated an operating profit of 6.5 trillion won ($4.47

billion) for the three months ended Dec. 31, versus a 7.7

trillion won LSEG SmartEstimate.
