Dell said its sales in the quarter ended 3 February were $20.1 billion, up 53 percent from the year-earlier period, which was before Dell purchased data storage tech firm EMC.
It reported adjusted net income of $1.1 billion for the quarter.
Revenue in Dell's client solutions group, which includes PCs and displays, rose 11 percent year over year to $9.8 billion. That is its best performance in more than eight quarters.
Dell did not give April-quarter guidance, but Wall Street thinks January-quarter's results have better implications for the PC businesses of PC-exposed companies. This includes HP, Intel, Western Digital and Seagate.
Dell shipped 11 million PCs in the fourth quarter, its largest volume since the fourth quarter of 2011. Its personal computer shipments were up 8.2 per cent year over year.
Dell's infrastructure solutions group generated $8.4 billion in revenue in the fourth quarter. That included $3.6 billion from servers and networking and $4.8 billion from storage. VMware revenue for the fourth quarter was $1.9 billion, Dell reported.
